Setting initial Django form field value in the __init__ method

Question

Django 1.6

I have a working block of code in a Django form class as shown below. The data set from which I\'m building the form field list can include an initial val

Answer 1

I had a similar problem setting the initial value for a radio button called 'needs_response' and solved it by inspecting self's attributes and referencing 'declared_fields':

    # views.py
    def review_feedback_or_question(request, template, *args, **kwargs):
        if 'fqid' in kwargs:
            fqid = kwargs['fqid']
        submission = FeedbackQuestion.objects.get(pk=fqid)
        form = FeedbackQuestionResponseForm(submission_type=submission.submission_type)
        # other stuff

    # forms.py
    class FeedbackQuestionResponseForm(forms.Form):
        CHOICES = (('1', 'Yes'), ('2', 'No'))
        response_text = forms.CharField(
            required=False,
            label='',
            widget=forms.Textarea(attrs={'placeholder': 'Enter response...'}))
        needs_response = forms.ChoiceField(choices=CHOICES,
            label='Needs response?',
            widget=forms.RadioSelect())
        def __init__(self, *args, **kwargs):
            if 'submission_type' in kwargs:
                submission_type = kwargs.pop('submission_type')
                if submission_type == 'question':
                    self.declared_fields['needs_response'].initial = 1
                else:
                    self.declared_fields['needs_response'].initial = 2
            super(FeedbackQuestionResponseForm, self).__init__(*args, **kwargs)
