Default Selection in ChoiceField

[Sumanth]

Hi all,

I have a basic form

class AssumptionsForm(forms.Form):
writedownoper = forms.ChoiceField( required=True, choices =
[('1','1'),('2',2='),('3','3')])

Now in my view after I create the form I want to set value 2 as
default. How can I do it? Is there set default API that I can use.

Thanks in advance
Sumanth

There are two ways you can do this. If the initial choice for
'writedownoper' will always be '2', you can use pass an 'initial'
argument when declaring the field [1]:

writedownoper = forms.ChoiceField( required=True, choices =

[('1','1'),('2','2'),('3','3')], initial = '2')

However, if that value needs to be dynamic, you can do so when
instantiating the form in your view [2]:

writedownoper = forms.ChoiceField( required=True, choices =

[('1','1'),('2','2'),('3','3')])

views.py:

form = AssumptionsForm(initial = {'writedownopen' : '2'})

You can do it in your view after creating the form, if you like.

form = SomeForm()
form.fields['meal_pref'].initial = 2
