title: Using sql server on django
body: <p>I have got following in my django env</p>
  
  <pre><code>Django==1.8.1
  django-mssql==1.6.2
  django-pyodbc==0.2.8
  pyodbc==3.0.10
  pywin32==219 
  sql-server.pyodbc==1.0
  </code></pre>
  
  <p>and the following in my settings.py</p>
  
  <pre><code>DATABASES = {
    'default': {
      'NAME': 'db_name',
      'ENGINE': 'sqlserver_ado',
      'HOST': 'host_name\\SQLEXPRESS',
      'USER': 'user_name',
      'PASSWORD': 'password',
    }
  }
  </code></pre>
  
  <p>But when I try to migrate it I face the following error. Am I missing out something?</p>
  
  <pre><code>django.core.exceptions.ImproperlyConfigured: 'sqlserver_ado' isn't an available database backend.
  Try using 'django.db.backends.XXX', where XXX is one of:
  'base', 'mysql', 'oracle', 'postgresql_psycopg2', 'sqlite3'
  Error was: cannot import name 'BaseDatabaseWrapper'
  </code></pre>
