Odoo

The videos:

could to try it

Usefully commands

python odoo-bin -d odoo -r odoo -w odoo

python odoo-bin scaffold om_hospital addons\

git commit -am "git commit -a --allow-empty-message -m ''"

Notes from the playlist

1. `manifest.py` file

"application": True,
"sequence": -100,

2. Adding the icon

create a directory "static"
create a directory "description"
add the image with name "icon" the image will automatically added

3. Creating Database Tables

each model is a table in the database contain whatever data, customer, sales history...etc

create a directory "models"
create the "__init__.py" file
create a file "patient.py"
in the main "__init__.py" add from . import models
in the models/__init__.py add from . import patient

In the patient.py:

from odoo import api, fields, models

class HospitalPatient(models.Model):
  # that will create a table with name "hospital_patient"
  _name = "hospital.patient"
  _description = "Hospital Patient"

  name = fields.Char(string="Name")
  age = fields.Integer(string="Age")
  # list with tubules (key,value)
  gender = fields.Selection([('male','Male'),('female', 'Female')], string="Gender")

Too see the changes:

in Apps, install/upgrade the model
in settings -> technical -> database structure -> modules
search for the table name

Another way

psql –U postgres
\c odoo the database name
select * from hospital_patient the model name

Note: add a space at the begging of select statement

4.Create Menu

create dir. views

inside views dir. create menu.xml file

<?xml version="1.0" encoding="utf-8"?>
<odoo>
  <menuitem id="menu_hospital_main" name="Hospital" action="" />
  <menuitem id="menu_patient_main" name="Patient Details" action="" parent="menu_hospital_main" />
  <menuitem id="menu_patient_details" name="Patients" action="" parent="menu_patient_main" />
</odoo>

import the menu file in the manifest file by
```
'data' :['views/menu.xml']
```

Too see the changes:

upgrade the model
more info about the model
installed features/ created menus

5.Create Window Action

create a patient.xml file

<?xml version="1.0" encoding="utf-8"?>
<odoo>

  <record id="action_hospital_patient" model="ir.actions.act_window">
    <field name="name">Patients</field>
    <field name="type">ir.actions.act_window</field>
    <field name="res_model">hospital.patient</field>
    <field name="view_mode">tree,form</field>
    <field name="context" eval="{}" />
    <field name="help" type='html'>
      <p class='o_view_nocontent_smiling_face'>
        Create your first patient!
      </p>
    </field>
  </record>

</odoo>

import it in the manifest file

'data' :['views/menu.xml','views/patient.xml']

Too see the changes:

upgrade the model
settings>technical>Window Actions
search for Name of your action

6. Link Menu And Actions

edit the menu to be :

<menuitem id="menu_patient_details" name="Patients" action="action_hospital_patient" parent="menu_patient_main" />

from the debugging icon, became a superuser
now u can see the hospital in the main menu

NOTE: to get an existing action go for it works and from the debugging icon, edit action

Important: must create any menuitem that uses an action, after their action. So the Patients menuitem will be moved to patient.xml, because the execution start in manifest in the data object, executing them one by one, so when it executes the menu.xml will find a menuitem that has an action that still didn't created, causing an error.

7. security rights

search in the logs for the access rules in custom_addons\hospital\security\ir.model.access.csv

id,name,model_id:id,group_id:id,perm_read,perm_write,perm_create,perm_unlink
hospital.access_hospital_patient,access_hospital_patient,hospital.model_hospital_patient,base.group_user,1,1,1,1

add access path to the manifest file

8. set menu icon

install web_responsive and add int to custom_addons

in custom_addons\hospital\views\menu.xml edited to be

<?xml version="1.0" encoding="utf-8"?>
<odoo>
  <menuitem id="menu_hospital_main" name="Hospital" sequence="0" web_icon="hospital,static\description\icon.png" />
  <menuitem id="menu_patient_main" name="Patient Details" sequence="0" parent="menu_hospital_main" />
</odoo>

then uninstall the model in the app list not the custom_addons

9+10. create tree and form view

NOTICE that here we will add here a filed called ref in the patient model, copy name filed and change its name to ref with string value Reference. (in custom_addons\hospital\models\patient.py)

ref = fields.Char(string="Recreance")

in custom_addons\hospital\views\patient_view.xml add this after <odoo>

  <record model="ir.ui.view" id="view_hospital_patient_tree">
    <field name="name">hospital patient</field>
    <field name="model">hospital.patient</field>
    <field name="arch" type="xml">
      <tree>
        <field name="name" string="Patient Name" />
        <field name="ref" />
        <field name="age" />
        <field name="gender" />
      </tree>
    </field>
  </record>


  <record model="ir.ui.view" id="view_hospital_patient_form">
    <field name="name">hospital patient</field>
    <field name="model">hospital.patient</field>
    <field name="arch" type="xml">
      <form>
        <sheet>
          <group>
            <group>
              <field name="name" />
              <field name="age" />
            </group>
            <group>
              <field name="gender" />
              <field name="ref" />
            </group>
          </group>
        </sheet>
      </form>
    </field>
  </record>

11. add search view

in custom_addons\hospital\views\patient_view.xml add this after form view

  <record model="ir.ui.view" id="view_hospital_patient_search">
    <field name="name">hospital patient</field>
    <field name="model">hospital.patient</field>
    <field name="arch" type="xml">
      <search string='test'>
        <field name="name" string="Patient Name" filter_domain="['|',('name', 'ilike', self),('ref', 'ilike', self)]" />
        <field name="age" />
        <field name="gender" />
      </search>
    </field>
  </record>

NOTES:

in filter_domain to have more than oen or condition,'|', add another '|' and add the condition
- filter_domain="['|','|',('name', 'ilike', self),('anotherValue', 'ilike', self),('ref', 'ilike', self)]"

12. add filter TO search view

NOTES:

separator to not allow the or operation, when u select more than one filter
< means less than,'<'.

  <record model="ir.ui.view" id="view_hospital_patient_search">
    <field name="name">hospital patient</field>
    <field name="model">hospital.patient</field>
    <field name="arch" type="xml">
      <search string='test'>
        <field name="name" string="Patient Name" filter_domain="['|',('name', 'ilike', self),('ref', 'ilike', self)]" />
        <field name="age" />
        <field name="gender" />
        <filter string="Male" name="filter_male" domain="[('gender','=','male')]" />
        <filter string="Female" name="filter_female" domain="[('gender','=','female')]" />
        <separator />
        <filter string="Kids" name="filter_kids" domain="[('age','&lt;=','5')]" />
        <group expand="0" string="Group By">
          <filter string="Gender" name="group_by_gender" context="{'group_by':'gender'}" />
        </group>
      </search>
    </field>
  </record>

13. archive and not

in custom_addons\hospital\models\patient.py add active filed

    active = fields.Boolean(string="Active", default=True)
    age = fields.Integer(string="Age")
    # list with tubules (key,value)
    gender = fields.Selection(
        [('male', 'Male'), ('female', 'Female')], string="Gender")
    name = fields.Char(string="Name")

in custom_addons\hospital\views\patient_view.xml add active filed

in form record

<group>
  <field name="gender" />
  <field name="ref" />
  <field name="active" invisible="1" />
</group>

in search record

<separator />
<filter string="Kids" name="filter_kids" domain="[('age','&lt;=','5')]" />
<separator />
<filter string="Archive" name="filter_archive" domain="[('active','=',False)]" />

14. Apply domain for a menu/view

model will be from patient.hospital

view:

 <?xml version="1.0" encoding="utf-8"?>
 <odoo>

   <record id="action_hospital_female_patient" model="ir.actions.act_window">
     <field name="name">Female Patients</field>
     <field name="type">ir.actions.act_window</field>
     <field name="res_model">hospital.patient</field>
     <field name="view_mode">tree,form</field>
     <field name="context">{}</field>
     <field name="domain">[('gender','=','female')]</field>
     <field name="help" type='html'>
       <p class='o_view_nocontent_smiling_face'>
             Create your first patient!
       </p>
     </field>
   </record>

   <menuitem id="menu_female_patient_details" name="Female Patients" action="action_hospital_female_patient" parent="menu_patient_main" />
 </odoo>

add it to the custom_addons\hospital_manifest_.py

'data': [
      'security/ir.model.access.csv',
      'views/menu.xml',
      'views/patient_view.xml',
      'views/female_patient_view.xml',
  ],

15. Set Default Value Using Context

in view, custom_addons\hospital\views\female_patient_view.xml

<field name="context">{"default_gender":"female","default_age":"20"}</field>

rather than keeping it empty

16. Set Default filter Using Context

in view, custom_addons\hospital\views\patient_view.xml

<field name="context">{'search_default_filter_male':1,'search_default_group_by_gender':1}</field>

17. Adding chatter

in custom_addons\hospital_manifest_.py
```
'depends': ['mail'],
```

in custom_addons\hospital\models\patient.py

 _name = "hospital.patient"
 _inherit = ['mail.thread', 'mail.activity.mixin']
 _description = "Hospital Patient"

in custom_addons\hospital\views\patient_view.xml in form view under the sheet tag

</sheet>
<div class="oe_chatter">
  <field name="message_follower_ids" widget="mail_followers" />
  <field name="activity_ids" widget="mail_activity" />
  <field name="message_ids" widget="mail_thread" />
</div>

18. Enable Tracking For Fields to show in the chatter

in custom_addons\hospital\models\patient.py add tracking attribute

active = fields.Boolean(string="Active", default=True)
age = fields.Integer(string="Age", tracking=True)
# list with tubules (key,value)
gender = fields.Selection(
    [('male', 'Male'), ('female', 'Female')], string="Gender", tracking=True)
name = fields.Char(string="Name", tracking=True)

19. Add searchpanel

in search tag in patient_view.xml in search view

<searchpanel>
  <field name="gender" icon="fa-user" enable_conter="1" />
</searchpanel>

20. Add Many2one Field

create model file, custom_addons\hospital\models\appointment.py

from odoo import models, fields, api

 class HospitalAppointment(models.Model):
     # that will create a table with name "hospital_appointment"
     _name = "hospital.appointment"
     _inherit = ['mail.thread', 'mail.activity.mixin']
     _description = "Hospital Appointment"

     patient_id = fields.Many2one('hospital.patient', 'Patient')

add it to init in model dir, custom_addons\hospital\models_init_.py

from . import models
from . import patient
from . import appointment

crete view (where we add the many2one field), custom_addons\hospital\views\appointment_view.xml

<?xml version="1.0" encoding="utf-8"?>
<odoo>

  <record model="ir.ui.view" id="view_hospital_appointment_tree">

 hospital.access_hospital_patient,access_hospital_patient,hospital.model_hospital_patient,base.group_user,1,1,1,1
 hospital.access_hospital_appointment,access_hospital_appointment,hospital.model_hospital_appointment,base.group_user,1,1,1,1

21+22. add date and datetime with default value

carful: Date and Datetime not date and datetime, Case sensitive

in custom_addons\hospital\models\appointment.py

appointment_time = fields.Datetime(
        string="Appointment Time", default=fields.Datetime.now)
booking_date = fields.Date(
    string="Booking Date", default=fields.Date.context_today)

in custom_addons\hospital\views\appointment_view.xml under the patient_id

<!-- form view -->
<field name="appointment_time" />
<field name="booking_date" />

23. Add Related Field

in custom_addons\hospital\models\appointment.py

gender = fields.Selection(related="patient_id.gender", readonly=True)

notice: readonly if False will allow to make change to the value and it is by default True in the related field

in custom_addons\hospital\views\appointment_view.xml under the patient_id

<!-- form view -->
<field name="gender" />

24. Add Computed Field, age

edit the age field
add date of birth field(dob)
crete the compute function
comment the age filter, because the computed field does not store in the DB

in custom_addons\hospital\models\patient.py

dob = fields.Date(string="Date of Birth")
age = fields.Integer(string="Age", tracking=True, compute='_compute_age')
# age = fields.Integer(string="Age", tracking=True, compute='_compute_age', store=True)

@api.depends('dob')
    def _compute_age(self):
        print("self................", self)
        for rec in self:
            today = date.today()
            if rec.dob:
                rec.age = today.year - rec.dob.year
            else:
                rec.age = 1

notice: we can store the age by adding the store attribute like the commented one. we can not track a field that is not stored in the database

in custom_addons\hospital\views\patient_view.xml

<!-- form view -->
<field name="dob"/>

<!-- search view -->
<!-- <separator /> -->
<!-- <filter string="Kids" name="filter_kids" domain="[('age','&lt;=','5')]" /> -->

25.onchange field

add field that will show the change, in model file
create the onchange function, in model file
add it in view

in custom_addons\hospital\models\patient.py

    ref = fields.Char(string="Reference")

    @api.onchange('patient_id')
    def onchange_patient_id(self):
        self.ref = self.patient_id.ref

in custom_addons\hospital\views\patient_view.xml

<field name="ref"/>

From NOW on KEEP appointment_view.xml and appointment.py opens

26. _rec_name, for appointment

it is what we see in the navigation bar!!
what will be seen if we used this value in many2one field

by default it is _rec_name = 'name'

in custom_addons\hospital\models\appointment.py

    _rec_name = "ref"

in custom_addons\hospital\models\patient.py

    appointment_id = fields.Many2one('hospital.appointmentg', 'Appointment', tracking=True)

in custom_addons\hospital\views\patient_view.xml

<field name="appointment_id"/>

27. notebook

at the end of the sheet tag add <notebook><page><group><field/>

in custom_addons\hospital\views\appointment_view.xml

  <!-- notebook -->
  <notebook>
      <page string="Prescription" name="prescription">
          <group>
              <field name="booking_date"/>
          </group>
      </page>
      <page string="Pharmacy" name="pharmacy">
      </page>
  </notebook>
</sheet>

notice: the name attribute is important because we will need it when we do an inhabitance

28. HTML field, prescription field

add it in the model
add it in the view
add placeholder attribute

in custom_addons\hospital\models\appointment.py

    prescription = fields.Html(string="Prescription")

in custom_addons\hospital\views\appointment_view.xml

<field name="prescription" placeholder="Enter your prescription"/>

29. Remove Create, Edit, Delete and Duplicate Options From Views

in from or tree tag add crete='0'

example:

<form
        create="0" 
        edit="0"
        delete="0"
        copy="0"
>

45. show sample data in the background when there is no data

in tree field add sample='1'

in custom_addons\hospital\views\appointment_view.xml

<tree decoration-success="state =='done'" decoration-info="state =='draft'" decoration-danger="state=='in_consultation'" sample='1'>

46. enable editing form tree view

after selecting the record in the tree view we can edit it

add to the tree view multi_edit='1'

<tree decoration-success="state =='done'" decoration-info="state =='draft'" decoration-danger="state=='in_consultation'" sample='1' multi_edit='1'>

47. change the state in the statusbar via a button

u could search in odoo for, action_done, action_cancel... etc

add buttons in the view with type object
create their object actions/methods
set their states attribute, when they will be shown

<!-- form view -->
<header>
    <button name="action_in_consultation" string="In Consultation" type="object" states="draft" class="oe_highlight"/>
    <button name="action_done" string="Done" type="object" states="in_consultation" class="oe_highlight"/>
    <button name="action_cancel" string="Cancel" type="object" states="draft,in_consultation" />
    <button name="action_draft" string="Draft" type="object" states="cancel" class="oe_highlight"/>

    def action_draft(self):
        for rec in self:
            rec.state = 'draft'

    def action_in_consultation(self):
        for rec in self:
            rec.state = 'in_consultation'

    def action_done(self):
        for rec in self:
            rec.state = 'done'

    def action_cancel(self):
        for rec in self:
            rec.state = 'cancel'

48. add hot keys for buttons

add data-hotkey='i', any letter available

<button name="action_in_consultation" string="In Consultation" type="object" states="draft" class="oe_highlight" data-hotkey='i'/>

49. add One2Many field, Pharmacy field

One2many results in many records connected to one record, like a bag containing many items

Many2one results in one record selected form many record, like an item form a bag

One2many in appointment from pharmacy

One -> appointment

Many -> Pharmacy

create the model, we want its many
in pharmacy, add a Many2one field with the appointment
in appointment, add One2many field and pass field from step 1
add the pharmacy One2many field to the view
create the tree and form view from one2 many field
in this case the product model have been used so we need to add it to the depends in the manifest file
add security access

pharmacy model at the end of custom_addons\hospital\models\appointment.py

class AppointmentPharmacyLines(models.Model):
    _name = 'appointment.pharmacy.lines'
    _description = 'Appointment Pharmacy Lines'

    product_id = fields.Many2one('product.product', required=True)
    price_unit = fields.Float(related='product_id.list_price')
    qty = fields.Integer(string='Quantity', default=1)
    appointment_id = fields.Many2one(
        'hospital.appointment', string='Appointment')

security access

om_hospital_g.access_appointmentg_pharmacy_lines,access_appointmentg_pharmacy_lines,om_hospital_g.model_appointmentg_pharmacy_lines,base.group_user,1,1,1,1

50. editable attribute in the tree tag in the pharmacy filed

  <page string='Pharmacy'>
    <field name="pharmacy_lines_id">
      <tree editable='bottom'>

bottom, will fill the data at the bottom of the list/tree
top, will fill the data at the top of the list/tree
without the editable, when adding a new line will show a pop up of the form

51. colum inviable based on value in the model

add boolean field
add attrs attribute to the field will be hidden, parent means the appointment model
add the condition of hide

in appointment model

hide_sales_price = fields.Boolean(string='Hide Sales Price')

<!-- First group -->
  <field name="hide_sales_price" groups="base.group_no_one"/>

<!-- Pharmacy page -->
<page string='Pharmacy'>

              <field name="qty"/>
          </group>
      </form>
  </field>
</page>

52. show only in the developer mode

add groups="base.group_no_one" to the field u wanna hide

  <field name="hide_sales_price" groups="base.group_no_one"/>

Back to the patient model

53. image field

in custom_addons\hospital\models\patient.py

image = fields.Image(string='Image')

      <field name="name" />
      <field name="dob" />
      <field name="age" />
    </group>

patient_tag

54. create tags model and use boolean_toggle widget

to create a model, will deal with 6 files:

MyModel.py, patient_tag.py

from email.policy import default

 from odoo import api, fields, models

 class PatientTag(models.Model):
     _name = 'patient.tag'
     _description = 'Patient Tag'

55->58 adding Many2many colored field

create color field, two types:
1. char: more options
2. integer: some given colors
add the fields to the view
in patient.py add many2many field, will crete a separate table
in patient view add many2many field, with options attribute and many2many_tag widget

in custom_addons\hospital\models\patient_tag.py

color = fields.Integer(
    string='Color',
)

color2 = fields.Char(
    string='Color2',
)

in custom_addons\hospital\views\patient_tag_view.xml in form view

<field name="color"  widget="color_picker" groups="base.group_no_one"/>

)

in tree and form view custom_addons\hospital\views\patient_view.xml

<field name="tag_ids" widget="many2many_tags" options="{'color_field': 'color'}" />

Notice: options="{'color_field': 'color'}" allows you to see the color of the tag. And sadly, if you tried color2 will not work!!

appointment

59. add activity view to the appointment

create the view
don't for get to add it to the view_mode

<record model="ir.ui.view" id="view_hospital_appointment_activity">
  <field name="name">hospital.appointment.activity</field>
  <field name="model">hospital.appointment</field>
  <field name="arch" type="xml">

    </activity>
  </field>
</record>

<!-- action -->
    <field name="view_mode">tree,form,activity</field>

60. enable the html code

add codeview':true at the beginning of the options attribute, because when I add it at the end, it work but for me

in prescription field in custom_addons\hospital\views\appointment_view.xml

<field name="prescription" placeholder="Enter your prescription"
      options="{'codeview': true, 'collaborative': true, 'resizable': true}"/>

cancel_appointment files

61+62. adding Wizard, transient model

for temporarily data usage

create dir. wizard
import wizard in main __init__.py file
create its own __init__.py file
create the my_model.py/cancel_appointment.py
define it in the ..access.csv
create my_model_wizard.xml/cancel_appointment_wizard.xml, will keep
create the the menu window action, and keep it in menu.xml, because step 8
add the relative path to __manifest__.py, wizards added before the views and after security
make the form as a pop up, target
editing the default footer

init files

custom_addons\hospital\wizard_init_.py

67. scaffold command

to create odoo model using command line

where u can find the odoo-bin file use this command python odoo-bin scaffold :my_model :my_path

python odoo-bin scaffold om_inheritance C:\Users\bashr\odoo\odoo\custom_addons\

68+69. inheritance, adding field

crate the model, my_inherited_model.py
init file
manifest file
add a field to an inherited view, this is the tricky part: since we will need to connect our field with an existing on on the desired view.
1. if we was able to find the field in the view, our new field will be added successfully
2. if not, we will have to look at the inherited views, and based on your luck and experience, u guess which one that might have this field 😅
download the model from the app store

my_inherited_model.py, in custom_addons\om_inheritance\models\sale_order.py:

from odoo import models, fields, api

class SaleOrder(models.Model):
    _inherit = 'sale.order'

    confirmed_user_id = fields.Many2one(

    </record>


  </data>
</odoo>

70. inherit a method

add inherited method to my_inherited_model.py,
- REMEMBER where u place the super will be affected by the execution sequence of python

inherit method syntax:

def action_inherit(self,arg1,arg2):
  # to_do before the execution of the inherited method
  super(MyModel,self).action_inherit(arg1,arg2)
  # to_do after the execution of the inherited method
  # if u dint place the super line, this method (action_inherit) will get executed not the inherited one!!!!

in custom_addons\om_inheritance\models\sale_order.py

def action_confirm(self):
    super(SaleOrder, self).action_confirm()
    print('Hi, I am working!! ..................')
    self.confirmed_user_id = self.env.user.id

Override Methods:

create, 71+72
write, 73
default_get, 74

71. overwrite Create method in patient model

in custom_addons\hospital\models\patient.py

  @api.model
  def create(self, vals_list):
      print("Odoo Metes are the best", vals_list)
      vals_list['ref'] = 'REFERENCE'
      return super(HospitalPatient, self).create(vals_list)

72. creating a sequence value and use it

crete sequence_data.xml in data rep.
add it to manifest file
use sequence value

sequence_data.xml, custom_addons\hospital\data\sequence_data.xml

<?xml version='1.0' encoding='utf-8'?>
<odoo>

  <record model="ir.sequence" id="seq_hospital_patient">
    <field name="name">Hospital Patient</field>
    <field name="code">hospital.patient</field>
    <field name="prefix">HP</field>

    'security/ir.model.access.csv',
    'data/patient_tag_data.xml',
    'data/patient.tag.csv',
    'data/sequence_data.xml',

Using the sequence, patient.py, custom_addons\hospital\models\patient.py

@api.model
def create(self, vals_list):
    print("Odoo Metes are the best",
          self.env['ir.sequence'].next_by_code('hospital.patient'))
    vals_list['ref'] = self.env['ir.sequence'].next_by_code('hospital.patient')
    return super(HospitalPatient, self).create(vals_list)

or to avoid losing one of sequence

@api.model
def create(self, vals_list):
    curr_seq = self.env['ir.sequence'].next_by_code('hospital.patient')
    print("Odoo Metes are the best", curr_seq)
    vals_list['ref'] = curr_seq
    return super(HospitalPatient, self).create(vals_list)

73. overwrite Write method/ Edit data of a patient

WHAT WE WILL BE DOING: if a record does not have a ref value and got updated, give it a ref value

NOTICE: vals.get('ref') to allow entering a value to ref filed.

self.ref==False the value in the DB is empty,
vals.get('ref')==False the value of the filed passed to the DB is empty.
vals in write method differ form create method, which it contain only the changed fields.

def write(self, vals):
    print('write trigger when we edit', vals)
    if not self.ref and not vals.get('ref'):
        self.ref = self.env['ir.sequence'].next_by_code(
            'hospital.patient')
    return super(HospitalPatient, self).write(vals)

74. adding the date_cancel field and overwrite default_get method

WHAT WE WILL BE DOING: Showing the current date in the date_cancel field, by overriding default_get method

custom_addons\hospital\wizard\cancel_appointment.py

@api.model
    def default_get(self, fields):
        res = super(CancelAppointmentWizard, self).default_get(fields)

75. name_get method, change the appearance of the patient model in the many2many fields

how the model display its fields in many2one, the changes will done in patient.py and shown in appointment model, the model that uses the patient.py as many2one field

in custom_addons\hospital\models\patient.py

def name_get(self):
    # result = []
    # for record in self:
    #     name = '[' + record.ref + '] ' + record.name
    #     result.append((record.id, name))
    # return result
    return [(record.id, "[%s] %s" % (record.ref, record.name)) for record in self]

Terminal Commands

1. run odoo from terminal

python_path odoo-bin_path -c odoo.conf_path

C:\python\python.exe C:\Users\bashr\odoo\odoo\odoo-bin -c C:\Users\bashr\odoo\odoo\odoo.conf

so what is odoo.conf?

C:\python\python.exe C:\Users\bashr\odoo\odoo\odoo-bin -h

will see a list of values you can assign, so what odoo.conf does is assigning those values, but we can do this inline we could try

--addons-path=C:\Users\bashr\odoo\odoo\odoo\addons,C:\Users\bashr\odoo\odoo\addons,C:\Users\bashr\odoo\odoo\custom_addons
-r odoo, database user
-w odoo, database password
--db_host=localhost
--db_port=5432
-p 8055, UI port

C:\python\python.exe C:\Users\bashr\odoo\odoo\odoo-bin --addons-path=C:\Users\bashr\odoo\odoo\odoo\addons,C:\Users\bashr\odoo\odoo\addons,C:\Users\bashr\odoo\odoo\custom_addons -r odoo -w odoo --db_host=localhost --db_port=5432 -p 8055

2. create odoo.conf from terminal

will add

--stop-after-init, stop after initialization
-s, save
-c :configuration_file_path, where it will be saved

3. install model from CLI

will add

-d, database name
-i :model_name, install

C:\python\python.exe C:\Users\bashr\odoo\odoo\odoo-bin -c C:\Users\bashr\odoo\odoo\odoo.conf -d odoo -i crm

4. fix Error no 98 Address Already In Use Error

that means that u have a process running on this port:

just change port number.
kill the process that running on this port

second solution (only Ubuntu/Linux):

ps aux||grep odoo
sudo kill -9 :process_id

5. upgrade model from CLI

will add

-d :database_name, to access this DB
-u :model_name, to upgrade this model

C:\python\python.exe C:\Users\bashr\odoo\odoo\odoo-bin -c C:\Users\bashr\odoo\odoo\odoo.conf -d odoo -u hospital

6. create database from CLI

will add

-d :database_name, to access this DB

C:\python\python.exe C:\Users\bashr\odoo\odoo\odoo-bin -c C:\Users\bashr\odoo\odoo\odoo.conf -d odoo_test

WIRED ERROR

for some reason when i tried to run odoo on the default port, 8069, did not work.

shows something like that: web.assets_common.min.js:4451 Uncaught (in promise) Error: QWeb2: Template

changing the port solved the issue, I changed it to 80 instead of 8069.

76. Set a Menu hierarchy (Menu And SubMenu) Without Specifying Parent & play ground model

Menu hierarchy

we can add to the root menu like this

   <menuitem id="menu_technical" name="Technical" parent='menu_hospital_main' sequence="110">
        <menuitem id="menu_playground" name="Play Ground" action='action_playground' sequence="110"/>
    </menuitem>

and we can add it as a main model like CRM or Sales

   <menuitem id="menu_technical" name="Technical" sequence="110">
        <menuitem id="menu_playground" name="Play Ground" sequence="10">
            <menuitem id="menu_playground2" name="Play Ground" action='action_playground' sequence="10">
            </menuitem>
        </menuitem>
    </menuitem>

77. difference b/w the action windows types

current: like the patient model
new: like wizards, the cancel appointment model
inline: like the playground model

inline vs current: Current window, will have the discard and save buttons, etc. But, this inline will not

in odoo_playground_view.xml

    <record id="action_playground" model="ir.actions.act_window">
        <field name="name">Play Ground</field>

        <field name="target">current</field>
        <field name="type">ir.actions.act_window</field>
    </record>

try and get it back to inline

self & env

self is a record set, record set is an object we can access its inner values.

self.env['hospital.appointment'].browse(6).patient_id.name self.env['hospital.appointment'].browse(6).action_done()

self.env['my.model'].browse(cids/id).patient_id.name

to get the record set of whatever inside

self.env.ref('hospital.patient_tag_vip').name self.env.ref('XML ID').name

XML ID, can be found when you open the view metadata from the debugging icon, in the needed view

78. active_id

Adding the appointment sequence:

appointment.py, adding field
appointment view, show it in the view
sequence_data.xml, adding the sequence
appointment.py, edit the create method

Using the active_id:

from view
form model

adding the appointment sequence

appointment.py, adding field, custom_addons\hospital\models\appointment.py

Note that we will commit the rec_name, since we wanna display the name field when we uses the active_id
```
# _rec_name = 'ref'

name = fields.Char(
    string='name',
    readonly=True
)
```

  <field name="prefix">OP</field>
  <field name="padding">5</field>
  <field name="company_id" eval="False" />
</record>

appointment.py, edit the create method, custom_addons\hospital\models\appointment.py

@api.model
def create(self, vals_list):
    print("Odoo Metes are the best",
          self.env['ir.sequence'].next_by_code('hospital.appointment'))
    vals_list['name'] = self.env['ir.sequence'].next_by_code(
        'hospital.appointment')
    return super(HospitalAppointment, self).create(vals_list)

adding active_id to view using button type action

custom_addons\hospital\views\appointment_view.xml

<!-- button type action -->
<button type='action' data-hotkey='n' name="%(action_cancel_appointment_wizard)d" string='Cancel' states='in_consultation,draft' context="{'default_appointment_id':active_id}" />

adding active_id to python file, which will display the rec_name of the model

edit the cancel_appointment.py wizard, custom_addons\hospital\wizard\cancel_appointment.py

@api.model
    def default_get(self, fields):
        res = super(CancelAppointmentWizard, self).default_get(fields)
        res['date_cancel'] = datetime.date.today()
        print(".................context", self.env.context)
        res['appointment_id'] = self.env.context.get('active_id')
        return res

79. hide field based on context

Note that we need two separate view files to apply this, ex:

appointment_view.xml and cancel_appointment_view.xml
female_patient_view.xml and patient_view.xml

steps:

add a marker to the context attribute to the record you wanna hide
add invisible attribute and get the value of that marker, in form view

Case 1: appointment_view.xml and cancel_appointment_view.xml

adding the marker, custom_addons\hospital\views\appointment_view.xml

<button type='action' data-hotkey='n' name="%(action_cancel_appointment_wizard)d" string='Cancel' states='in_consultation,draft' context="{'hide_appointment': 1}" />

invisible attribute, custom_addons\hospital\wizard\cancel_appointment_wizard.xml

<field name="appointment_id" invisible="context.get('hide_appointment')" />

Case 2: female_patient_view.xml and patient_view.xml, hide gender

adding the marker, custom_addons\hospital\views\female_patient_view.xml

<field name="context">{"default_gender":"female","default_age":20,"hide_gender":1}</field>

invisible attribute, custom_addons\hospital\views\patient_view.xml

<field name="gender" invisible="context.get('hide_gender')" />

80. rising a validation error

_ is for translation purpose

from odoo import api, fields, models, _
from odoo.exceptions import ValidationError

# ...some code here

def action_cancel(self):
    if self.appointment_id.booking_date == fields.Date.today():
        raise ValidationError(
            _("Sorry, cancellation is not allowed on the same day of booking !"))
    return

81. Apply domain field, can be done in xml or python

in custom_addons\hospital\wizard\cancel_appointment_wizard.xml

<field name="appointment_id" invisible="context.get('hide_appointment')" domain="[('state', '=', 'draft')]" />

in custom_addons\hospital\wizard\cancel_appointment.py

appointment_id = fields.Many2one(
    string='Appointment',
    comodel_name='hospital.appointment',
    domain=[('state', '=', 'draft'), ('priority', 'in', ('0', '1', False))]
)
