title: Django model.save() not writing to database
body: <p>I'm new to Django and just trying to submit a form using ModelForms to create a new event and save it to the database.</p>
  
  <p>I am trying to insert rows into three tables: Location, Event (which has a location_id FK), and EventSchedule (which as an event_id FK).</p>
  
  <p>Here is the method that saves the forms. When it is called, no errors are returned, yet the new rows are not inserted into the database.:</p>
  
  <p><strong>addNewEvent()</strong> (in views.py)</p>
  
  <pre><code>def addNewEvent(self, event_form, location_form, event_sched_form, latitude, longitude):
  
      new_event = event_form.save(commit=False)
      new_location = location_form.save(commit=False)
      new_event_sched = event_sched_form.save(commit=False)
      # set any necessary values and save forms
      new_location.latitude = latitude
      new_location.longitude = longitude
      new_location.save()
      new_event.flagged = False
      new_event.location = new_location
      new_event.save()
      new_event_sched.event = new_event
      new_event_sched.save()
  </code></pre>

  <p><strong>EDIT:</strong></p>
  
  <p>I can't even save a Model, let alone a ModelForm (even though I am doing it successfully in other places). I added the following code to associate a user with an event. No errors, yet it doesn't add a row to the database:</p>
  
  <pre><code>new_user_event = UserEvent(user=user,
                                  event=new_event,
                                  datetime_created=datetime.datetime.now())
  new_user_event.save()
  </code></pre>
  
  <p>Any ideas?</p>
  
  <p><strong>EDIT 2:</strong></p>
  
  <p>Screenshot of new_user_event: <a href="http://imgur.com/JUauG" rel="nofollow">http://imgur.com/JUauG</a></p>
  
  <p><strong>EDIT 3:</strong></p>
  
  <p>This is how I'm instantiating the ModelForms:</p>
  
  <pre><code>event_form = EventForm(request.POST or None)
  location_form = LocationForm(request.POST or None)
  event_sched_form = EventScheduleForm(request.POST or None)
  </code></pre>
