title: 'WSGIRequest' object has no attribute 'user' in Google App Engine
body: <p>I'm new to django and Google App Engine, and I'm having trouble with using the datastore. Every time I make a query, such as</p>
  
  <pre><code>db.GqlQuery("SELECT * FROM Listing ORDER BY date DESC LIMIT 10")
  </code></pre>
  
  <p>I receive the error:</p>
  
  <pre><code>'WSGIRequest' object has no attribute 'user'
  </code></pre>
  
  <p>This error seems to be generated in context_processors.py within the django core. Now, the advice I've found on the Internet said to comment out user-related INSTALLED_APPS and MIDDLEWARE_CLASSES, but this does not seem to help. My code looks like this:</p>
  
  <pre><code>MIDDLEWARE_CLASSES = (
  #    'django.middleware.common.CommonMiddleware',
  #    'django.contrib.sessions.middleware.SessionMiddleware',
  #    'django.contrib.auth.middleware.AuthenticationMiddleware',
  #    'django.middleware.doc.XViewMiddleware',
  )
  
  INSTALLED_APPS = (
  #    'django.contrib.auth',
      'django.contrib.contenttypes',
  #    'django.contrib.sessions',
      'django.contrib.sites',
  )
  </code></pre>
  
  <p>My Listing object is defined as the following (it had a author property earlier, but this is now commented out and the object was redefined with a new name):</p>
  
  <pre><code>class Listing(db.Model):
      #author = db.UserProperty()
      address = db.StringProperty()
      date = db.DateTimeProperty(auto_now_add=True)
      coords = db.GeoPtProperty()
  </code></pre>
  
  <p>Does anyone know what is causing this error, and how to fix it? Is it perhaps a case of having to reset the settings somehow?</p>
