initial value in radio button django form

Question

how can I declare initial value of radio button?

form.py

YESNO = (
    ('Yes','Yes'),
    ('No', 'No'),
)
class MyForm(forms.Form):
   like = forms.ChoiceField(widget=forms.RadioSelect, choices=YESNO)

myhtml.html

{{form.like}}

i try to put:

like = forms.ChoiceField(widget=forms.RadioSelect, choices=YESNO, initial={'Yes':'Yes'})

when i run my code, my radio button has not yet selected..

Answer 1

Yes, this should be done in the view, but the syntax in the accepted answer is incorrect, as it will trigger field validation on all fields before submitting the form. Use instead:

def myviews(request):
  .....
  form = MyForm(initial={'like':'Yes'})
  ...
