title: django 1.7 migrate gets error "table already exists"
body: <p>I am trying to apply a migration but am getting the error:</p>
  
  <blockquote>
    <p>django.db.utils.OperationalError: (1050, "Table 'customers_customer'
    already exists")</p>
  </blockquote>
  
  <p>I get this by issuing the following command:</p>
  
  <pre><code>python manage.py migrate
  </code></pre>
  
  <p>My customer table already exists, so what do I do to let the migration know this, not error out, and run my modification to my model?</p>
  
  <p>I ran this on my local environment with local database with no problem.  It is when I pointed my database to production and ran <code>migrate</code> above that I get this error.</p>
