Any idea? > I think it's something related to that admin.site.unregister(model) and admin.site.register(model, model_admin) doesn't truly swap the ModelAdmin site, because I get two different MyModelAdmin objects if I query the admin.site._registry[model] compared to print "self" on the ModelAdmin.add_view() # on my method print admin.site._registry[model] <my_app.admin.MyModelAdmin object at 0x3e0ed10> #on ModelAdmin.add_view() print self <my_app.admin.MyModelAdmin object at 0x3ed4b40> what I have to do to truly change the modeladmin at runtime ? -- Marc -- You received this message because you are subscribed to the Google Groups "Django users" group.
