How to add data to a django admin change_list page taken from a different model?

I would like to add a bit of information to a certain change_list admin page. The info is taken from a queryset on a different model than that presented in this template. How do I go about doing this?

Use a Custom Template Tag - you can fetch and use anything in it.

Try to rewrite changelist_view function in your admin class:

class MyModelAdmin(admin.ModelAdmin):
    # .....
    def changelist_view(self, request, extra_context=None):
        extra = {'foo': bar}
        extra.update(extra_context or {})
        return super(MyModelAdmin, self).changelist_view(request, extra_context=extra)
    # .....

You can create a custom context processor. This allows you to expose a variable to the whole application. It works on pages rendered using RequestContext, tried this with the admin pages and it works.
