Here is an example of get_choices() output ... it comes from a method
on the Question model.
[('A', 'A - Once?'), ('B', 'B - Twice?'), ('C', 'C - Four times?'),
('D', 'D - Twelve times?'), ('E', 'E - Continously as changes are
made?')]
It is available before the the answer form is instantiated ...
class AnswerSingleForm(forms.ModelForm):
class Meta:
model = Answer
fields = [
'answer',
'score'
]
This is my new form which seems to work ...
class AnswerSingleForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(AnswerSingleForm, self).__init__(*args, **kwargs)
answer = kwargs['instance']
choices = answer.question.get_choices()
if len(choices) > 0:
self.fields['answer'] = forms.ChoiceField(
choices=choices
)
class Meta:
model = Answer
fields = [
'answer',
'score'
]
So how do I get that set of choices into the Answer form?
I can see from the docs that the form Meta class can have a widgets
attribute for the 'answer' field. I think I need a ChoiceField widget
so I can include the choices. I tried using __init__() in the form
class to get the choices on board at instantiation but still couldn't
get it going because class Meta doesn't see 'self'.
Thanks for any help
