How can I limit a 'list_filter' to a certain subset of objects?

[Rodrigo Cea]

Explanation:

I have 3 models: Client, Project and Task. Each Client has 1 or more Projects. Each Project has 1 or more Tasks.

 

A Client can only see the Projects assigned to him and the Tasks assigned to one of his Projects. This is already working, overriding "queryset" in the ModelAdmin instance.

However, in the changelist for Tasks, there is a list_filter on Projects, so a Client can view the Tasks that are assigned to a certain Project. 

THE PROBLEM: this 'Project' filter shows all Projects, whether they're assigned to the Client or not. I need it to only show the Projects assigned to the Client.

Thanks, 

Rodrigo

Hello, Rodrigo

From looking at the ModelAdmin source code[1], I think all you need to do is reimplement the queryset() method in your subclass on admin.py.

Make sure you return a filtered queryset based on request.user. I never use the admin, so I'm not so sure about how the user will be accessible from the admin, so maybe someone else will have to explain the final steps.
