title: South with django 1.7
body: <p>I'm using django 1.7 for my application. I came across several problems with migrate. Everytime I try to change a field name in models which is a foreign key, it breaks. The only fix would be to go to database and fix it, and they run <code>migrate</code> followed by <code>syncdb</code>.
  How do I solve these as my application is turning bigger, and i'll soon be spending more time in resolving the database errors as my schema changes.
  South is not supported for django 1.7 and has its own migration which is not powerful?(I'm not sure, just a beginner)</p>
