Mixing
Assigning user permissions with post_save signal
I have a custom User model called EmailUser and I'm trying to assign a custom model permission on post_save. I have the following signal in models.py
@receiver(post_save, sender=EmailUser)
def assign_permissions(sender, **kwargs):
emailUser = kwargs["instance"]
if kwargs["created"]:
permission = Permission.objects.get(name='Can view polls')
emailUser.user_permissions.add(permission)
print emailUser.user_permissions.all()
The print statement returns the expected: [<Permission: polls | poll | Can view polls>] but when I look at the user in admin the permission is not selected and when I check it in shell, the permissions are empty.

Could you tryemailUser.save()before adding the permission to the user.

@oppositeday did you figure out a solution? I'm having a similar problem.

I had exactly the same problem, I tried to use post_save|pre_save|redefining save() model method|redefining model_save() method in admin.py file, but I didn't get the expected behavior(don't see selected permissions in the admin interface)
So I started investigating this question and found in django.contrib.admin.options file, ModelAdmin class, _changeform_view method the next code:
self.save_model(request, new_object, form, not add)
self.save_related(request, form, formsets, not add)
So firstly instance is saved by save_model and then permissions are rewritten by save_related
So I just redefined changeform_view in my UserAdmin class
My redefined code listing is the next:
def changeform_view(self, request, object_id=None, form_url='', extra_context=None):
to_field = request.POST.get(TO_FIELD_VAR, request.GET.get(TO_FIELD_VAR))
obj = self.get_object(request, unquote(object_id), to_field)
user = get_object_or_404(User, id=obj.id)
if user.is_lab_director:
permission = Permission.objects.get(name='Can change job')
user.user_permissions.add(permission)
else:
user.user_permissions.clear()
with transaction.atomic(using=router.db_for_write(self.model)):
return self._changeform_view(request, object_id, form_url, extra_context)
I hove this help someone to solve such question
