Project structure

• init.py: This is a blank Python script that due to its special name let’s Python know that this directory can be treated as a package
• settings.py: This is where you will store all your project settings
• urls.py: This is a Python script that will store all the URL patterns for your project. Basically the different pages of your web application.
• wsgi.py: This is a Python script that acts as the Web Server Gateway Interface. It will later on help us deploy our web app to production
• manage.py: This is a Python script that we will use a lot. It will be associates with many commands as we build our web app!

Migration Warning

You have 18 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions.
Run 'python manage.py migrate' to apply them.

What is migration ?

• A migration allows you to move databases from one design to another, this is also reversible.

Terminologies

• A Django Project is a collection of applications and configurations that when combined together will make up the full web application (your complete website running with Django)
• A Django Application is created to perform a particular functionality for your entire web application. For example you could have a registration app, a polling app, comments app, etc.
• These Django Apps can then be plugged into other Django Projects, so you can reuse them! (Or use other people’s apps)

Templates

• The template will contain the static parts of an html page (parts that are always the same)

Migration

• python manage.py migrate
• python manage.py makemigrations APP_NAME
• python manage.py migrate

Super User

• To create a superuser: python manage.py createsuperuser
