Changing the objects manager without affecting the admin interface ?

[happy]

Hello All,

I would like to change the objects manager for a Worker class such
that it only outputs workers for which the user auth.user is active in
the system. The idea is to make invisible the  workers that do not
have an active account. The problem if I do that is that the inactive
workers will also disappear from the admin.

As this is too annoying for me. currently, I have just added another
manager named active_objects and replaced Worker.objects by
Worker.active_objects everywhere in my code.
The problem with this approach is that it does not work well with
one_to_many or many_to_many relationships manager. These still show
the inactive users.

What is the clean way to do this ?

Have a problem with a first Django App due to the Web Tutoral

[Happy Data Scientist]

Dear Friends !

I have an error when I tried to develop my first Django App due to the Web 
Tutoral: 
https://docs.djangoproject.com/en/1.8/intro/tutorial02/

The error is  "ImportError at /admin/" -- cannot import name 'resolve_url'" 
for the address "http://127.0.0.1:8000/admin/";
The Django version is 1.8.3

Could you help me to resolve this issue ?

Thanks ahead
