Set user permission via python

[ma...@anthemdisplays.com]

Hi,

I'm trying to set a permission for a user that I'm creating with a python script. I've tested and found that the codename for the permission is "display_data.settings" using the following:

python manage.py shell

from django.contrib.auth.models import User

user_name = User.objects.get(username="user_name")

user_name.get_all_permissions()

set([u'display_data.settings']) 

I'm trying to set this permission for the user with the following:

from django.contrib.auth import get_user_model

from django.contrib.auth.models import User, Permission

User = get_user_model()

#check to see if user exists, create it if it doesn't

User.objects.filter(username="user_name").exists() or\

    User.objects.create_user(username='user_name', email='user...@example.com', password='blah')

 

#add permissions to user

u = User.objects.get(username="user_name")

permission = Permission.objects.get(name='display_data.settings')

u.user_permissions.add(permission)

 

When I run this, I get the following error:

django.contrib.auth.models.DoesNotExist: Permission matching query does not exist.

Can anybody tell me what I'm missing?

I've solved this. First of all, the codename for the permission should be called as a codename and second, I had to remove the app name (display_data) like this:

permission = Permission.objects.get(codename='settings')

Glad you've found the solution. 

One thing I wanted to advice you is to use the get_or_create method on User.

For more detail check the django documentation.

So:

u, created = User.objects.get_or_create(username="user_name", defaults={email='user...@example.com', password='blah'})

Correction:

u, created = User.objects.get_or_create(username="user_name", defaults={'email': 'user...@example.com', 'password': 'blah'})
