title: Django ModelForm has no model class specified
body: <p>I am trying to use ModelForm:</p>
  
  <pre><code>from django.db import models
  from django.forms import ModelForm
  
  class Car(models.Model):
      carnumber = models.CharField(max_length=5)
  
      def __unicode__(self):
          return self.carnumber
  
  class PickForm(ModelForm):
      class Meta:
          Model = Car`
  </code></pre>
  
  <p>I have checked this and I cannot find my error.  When I call the view in a browser, it gives me the following error:</p>
  
  <pre><code>ModelForm has no model class specified
  </code></pre>
  
  <p>I have tested the view that calls the model with simple "foo bar" code at the same URL, but when I try this code, I get the class error above.</p>
