title: Django Rest Framework Without Database
body: <p>I'm trying to setup a simple API using Django Rest Framework, the problem is that my API does not have any database but the framework won't work without database setting.</p>
  
  <p>Here is my Django Rest Framework configuration in <code>settings.py</code>:</p>
  
  <pre class="lang-python prettyprint-override"><code>INSTALLED_APPS = [
      'provider',
      'django_nose',
      'rest_framework',
      'django.contrib.contenttypes',
  ]
  
  REST_FRAMEWORK = {
      'DEFAULT_AUTHENTICATION_CLASSES': [],
      'DEFAULT_PERMISSION_CLASSES': [],
  }
  </code></pre>
  
  <p>The error which I got is:</p>
  
  <blockquote>
    <p>ImproperlyConfigured("settings.DATABASES is improperly configured.
    "django.core.exceptions.ImproperlyConfigured: settings.DATABASES is
    improperly configured. Please supply the ENGINE value. Check settings
    documentation for more details.</p>
  </blockquote>
  
  <p>Is there any minimal settings which does not include <code>django.contrib.contenttypes</code> and <code>django.contrib.auth</code>?</p>
