[Django]-Django / Python, Using Radio Button for boolean field in Modelform?

Does this work?

class createdbentry(forms.ModelForm):

    choices = ( (1,'Yes'),
                (0,'No'),
              )

    class Meta:
        model = Mymodelname

    def __init__(self, *args, **kwargs):
        super(createdbentry, self).__init__(*args, **kwargs)

        BinaryFieldsList = ['FirstFieldName', 'SecondFieldName', 'ThirdFieldName']
        for field in BinaryFieldsList:
            self.fields[field].widget = forms.RadioSelect(choices=choices)
