Exposing multiple db in admin interface is limited

[idle sign]

Suppose I have Django driven site with two applications using two different dbs.

Documentation at ​http://docs.djangoproject.com/en/dev/topics/db/multi-db/ gives us an idea of how to expose multiple dbs to admin interface.

However four admin.ModelAdmin methods customized in the example do not handle list_filter option (so query hits the default db, and that rises an exception).

For now I've found only one working solution - using custom manager with overriden get_query_set() method.

The documentation says that the admin doesn't have explicit support for multiple databases. Adding explicit support is an area for improvement.

Using routers, it should be possible to use multi-db and the admin for many use cases (in particular, master-slave replication). There will certainly be use cases that admin will have difficulty with.

I'll leave this open as a someday/maybe ticket, given that this is a documented limitation. However, This is something that will need a specific proposal in order to go further.
