How to add custom permission to the User model in django?

You could do something like this:

in the __init__.py of your Django app add:

from django.db.models.signals import post_syncdbfrom django.contrib.contenttypes.models import ContentTypefrom django.contrib.auth import models as auth_modelsfrom django.contrib.auth.models import Permission# custom user related permissionsdef add_user_permissions(sender, **kwargs):    ct = ContentType.objects.get(app_label='auth', model='user')    perm, created = Permission.objects.get_or_create(codename='can_view', name='Can View Users', content_type=ct)post_syncdb.connect(add_user_permissions, sender=auth_models)

I don't think there is a "right" answer here, but i used the exact same code as you except i changed Permission.objects.create to Permission.objects.get_or_create and that worked find to sync with syncdb

An updated answer for Django 1.8. The signal pre_migrate is used instead of pre_syncdb, since syncdb is deprecated and the docs recommend using pre_migrate instead of post_migrate if the signal will alter the database. Also, @receiver is used to connect add_user_permissions to the signal.

from django.db.models.signals import pre_migratefrom django.contrib.contenttypes.models import ContentTypefrom django.contrib.auth import models as auth_modelsfrom django.contrib.auth.models import Permissionfrom django.conf import settingsfrom django.dispatch import receiver# custom user related permissions@receiver(pre_migrate, sender=auth_models)def add_user_permissions(sender, **kwargs):    content_type = ContentType.objects.get_for_model(settings.AUTH_USER_MODEL)    Permission.objects.get_or_create(codename='view_user', name='View user', content_type=content_type)
