title: Python Django 1.9 migrate error 'error creating new content types...'
body: <p>I am using Python 3.4 and Django 1.9.1 and I am trying to migrate my new model. First I write: python manage.py makemigrations missions in the command prompt and that worked without issue. But then I input:</p>
  
  <p>python manage.py migrate missions</p>
  
  <p>But I keep getting this error about the contenttypes:</p>
  
  <p>'error creating new content types. Please make sure contenttypes is migrated before trying to migrate apps individually'</p>
  
  <p>I've tried looking around at similar stackoverflow question but nothing has been helpful. How do I get this error to stop? One such solution at <a href="https://stackoverflow.com/questions/29917442/error-creating-new-content-types-please-make-sure-contenttypes-is-migrated-befo">Error creating new content types. Please make sure contenttypes is migrated before trying to migrate apps individually</a> stated:</p>
  
  <p>By manually removing the column name from 'django_content_type' table. Eg.</p>
  
  <p>'ALTER TABLE django_content_type DROP COLUMN name'</p>
  
  <p>But how do I do that? So far I haven't figured out how to use pure SQL statements like this in Django. I am using the PostgreSQL and I keep getting into all sorts of problems. Please help. Below is my missions model:</p>
