 Remove the include(). Just give the module and function name (e.g., {{{'myproject.apps.polls.views.polls.index'}}}) as a string, with no include() around it.

+
+== Blank object names ==
+
+==== Symptom ====
+
+The automatic admin interface is showing nothing (or a single {{{ }}}) in the "Select [object_type] to change" view.
+
+==== Probable cause ====
+
+You may have forgotten to create a {{{__repr__()}}} function for your model. Django calls {{{__repr__()}}} to find out how to display objects in the admin interface.
+
+==== Solution ====
+
+Add a {{{__repr__()}}} function to all your models. Make it a habit so it becomes automatic.
