title: Display a boolean model field in a django form as a radio button rather than the default Checkbox
body: <p>This is how I went about, to display a Boolean model field in the form as Radio buttons Yes and No.</p>
  
  <pre><code>choices = ( (1,'Yes'),
              (0,'No'),
            )
  
  class EmailEditForm(forms.ModelForm):
  
      #Display radio buttons instead of checkboxes
      to_send_form = forms.ChoiceField(choices=choices,widget=forms.RadioSelect)
  
      class Meta:
      model = EmailParticipant
      fields = ('to_send_email','to_send_form')
  
      def clean(self):
      """
      A workaround as the cleaned_data seems to contain u'1' and u'0'. There may be a better way.
      """
  
      self.cleaned_data['to_send_form'] = int(self.cleaned_data['to_send_form'])
      return self.cleaned_data
  </code></pre>
  
  <p>As you can see in the code above, I need a clean method that converts input string to an integer, which may be unnecessary.</p>
  
  <p>Is there a better and/or djangoic way to do this. If so, how?</p>
  
  <p>And no, using <code>BooleanField</code> seems to cause a lot more problems. Using that seemed obvious to me; but it isn't. Why is it so.</p>
