Question

The permission/authentication documentation for Django 1.4 provides the following snippet for creating custom permissions programmatically:

Edit: (I would like to employ this for permissions that are not necessarily linked to a specific model class, but more general permissions that span multiple types.)

from django.contrib.auth.models import Group, Permission
from django.contrib.contenttypes.models import ContentType

content_type = ContentType.objects.get(app_label='myapp', model='BlogPost')
permission = Permission.objects.create(codename='can_publish',
                                       name='Can Publish Posts',
                                       content_type=content_type)

My question is where this code should be placed. Obviously these should only be created once, but I don’t want to have to do it in the shell. It seems like this should be stored in a file somewhere. (For documentation sake.)

Usually it is enough to just add the needed permissions to the corresponding model class using the permissions meta attribute.

This is from the official documentation:

class Task(models.Model):
    ...
    class Meta:
        permissions = (
            ("view_task", "Can see available tasks"),
            ("change_task_status", "Can change the status of tasks"),
            ("close_task", "Can remove a task by setting its status as closed"),
        )
