Hi,
Problem: Empty migration doesn't show user friendly message.
When i run "python manage.py migrate" with no new migrations to be
applied it show me error message "AttributeError: '_Meta' object has no
attribute 'model_name'" instead of showing user friendly message "no
migration to apply".
I have using python3.4.1, django 1.8.3
Steps to replicate: First run migrate command to apply all migrations, Next
re-run same command again.
Below is trackback for reference.
Synchronizing apps without migrations:
Creating tables...
Running deferred SQL...
Installing custom SQL...
Running migrations:
No migrations to apply.
Traceback (most recent call last):
File "manage.py", line 9, in <module>

Did anyone face similar issue?
