Django 1.8 migrations showing "AttributeError"

[vijay kumar]

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 
execute_from_command_line(sys.argv)
  File "/lib/python3.4/site-packages/django/core/management/__init__.py",

line 170, in _detect_changes
old_field.rel.through._meta.model_name,

Did anyone face similar issue?
