This is how I went about, to display a Boolean model field in the form as Radio buttons Yes and No.

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

As you can see in the code above, I need a clean method that converts input string to an integer, which may be unnecessary.

Is there a better and/or djangoic way to do this. If so, how?

And no, using BooleanField seems to cause a lot more problems. Using that seemed obvious to me; but it isn't. Why is it so.
