Permissions Processing Code

This is a simple Python code that manages permissions associated with a document in Frappe framework. It is released under the MIT License.

Features

The code provides the following features:

Process permissions: The code defines a function process_permissions that is called when a document is saved or deleted. This function is responsible for managing the permissions associated with the document.
Field metadata: The code uses the meta property of the document to retrieve the fields of type Table MultiSelect with the options set to Permission Detail. This metadata is used to retrieve the existing permissions associated with the document.
Permissions map: The code creates a map of existing permissions associated with the document using the permissions_map dictionary. This map is used to create new permission records if they do not exist.
Get existing permissions: The code retrieves existing permission records associated with the document using the frappe.get_all function.
Create new permission records: The code creates new permission records using the add_permission_record function. This function takes in several parameters such as the reference doctype, reference docname, row id, doctype name, and docname.
Delete permission records: The code deletes permission records associated with the document using the frappe.delete_doc function.
Ignore permissions: The code uses the ignore_permissions=True parameter while creating and deleting permission records. This parameter allows the code to bypass permission checks while performing these operations.

To use this code, you can copy the permissions.py file to your Frappe application and include the following line in your document's Python file:

from myapp.my_module.permissions import process_permissions

You can then call the process_permissions function from within your document's on_update and on_trash methods.

def on_update(self):
    process_permissions(self, "on_update")

def on_trash(self):
    process_permissions(self, "on_trash")
