Django Forms HorizontalRadioSelect Renderer not working.

[Shazia Nusrat]

Hi,

I need to select form values horizontally but couldn't get it work.

Following is the code:

class HorizontalRadioRenderer(forms.RadioSelect.renderer):
  def render(self):
    return mark_safe(u'\n'.join([u'%s\n' % w for w in self]))

class ResponseForm(models.ModelForm):
    class Meta:
        model = Response
        fields = ('interviewer', 'interviewee', 'conditions', 'comments')

    def __init__(self, *args, **kwargs):
        # expects a survey object to be passed in initially
        survey = kwargs.pop('survey')
        self.survey = survey
        super(ResponseForm, self).__init__(*args, **kwargs)
        self.uuid = random_uuid = uuid.uuid4().hex

        # add a field for each survey question, corresponding to the question
        # type as appropriate.
        data = kwargs.get('data')
        for q in survey.questions():
            if q.question_type == Question.TEXT:
                self.fields["question_%d" % q.pk] = forms.CharField(label=q.text,
                    widget=forms.Textarea)
            elif q.question_type == Question.RADIO:
                question_choices = q.get_choices()
                self.fields["question_%d" % q.pk] = forms.ChoiceField(label=q.text,
                    widget=forms.RadioSelect(renderer=HorizontalRadioRenderer),
                    choices = question_choices)

Error:

    class HorizontalRadioRenderer(forms.RadioSelect.renderer):
AttributeError: type object 'RadioSelect' has no attribute 'renderer'

Please advise

Which version of Django are you using? From 1.11 the widgets changed to a template mechanism.

https://docs.djangoproject.com/en/1.11/ref/forms/widgets/#radioselect

Maybe this can help:

I am using Djnago 1.11.1. I've tried template approach but perhaps I've missed out something. 

If you can provide me some workable example I will be really really thankful.

Replace renderer=HorizontalRadioRenderer with attrs={'class': 'inline'} and then style radio elements using CSS. contrib.admin uses this approach. Here's the CSS:
