Adding permissions to user for testing

You can add permissions to a user in a test method with the following syntax, where {user} is a user object and {permission} is a permission object:

{user}.user_permissions.add({permission})

A user object can be created by importing get_user_model from django.contrib.auth, and instantiating a new user. You can access a particular permission object by importing Permission from django.contrib.auth.models, then using Permission.objects.get(codename='permission_name').

Here is a test example that uses these techniques:

# tests.py

from django.contrib.auth import get_user_model
from django.contrib.auth.models import Permission
from django.test import TestCase

User = get_user_model()


class MyTest(TestCase):

	def test_permission(self):
		user = User.objects.xreate_user(
			username='testuser',
			email='testuser@email.com',
			password='testpass123'
		)
		my_permission = Permission.objects.get(codename='my_permission')
		
		user.user_permissions.add(permission)
		
		...		# test permission
