Question

I have a simple model form:

 class ProductSelectionForm(ModelForm):
     class Meta:
         model = Product

and the model:

class Product(models.Model):
     name = models.CharField(max_length=155)

     def __unicode__(self):
         return self.name

But if I render the form using the {{ form.as_p }} tag it just renders the form as a single text input. How can I get the form to render as radio select options, with the name as the option label and the pk as the value? I have tried using widget but no joy.

Any help much appreciated.

You don’t want a modelform for that. They’re for creating and editing model instances. Instead, what you seem to want is a form to choose existing instances: for that, use a normal form with a ModelChoiceField:

class ProductSelectionForm(forms.Form):
    choice = forms.ModelChoiceField(queryset=Product.objects.all(), 
                                    widget=forms.RadioSelect)
