How to add a custom permission to a group in Django?

Question

I think I have coded a custom permission in a model:

class Foo(models.Model):
    class Meta:
        permissions = [('admin_foo', 'Can administrate foo'),]
    ...

I ran the commands to store the permission:

python manage.py makemigrations
python manage.py migrate

Then I have a decorator on my protected view:

@permission_required('app.admin_foo')
def myFooView(request):
    ...

How do I add this permission to the group "bar" programmatically?

Answer 1

permission = Permission.objects.get(codename=perm_name)
group.permissions.add(permission)
