Hi all
I'm having problems in saving a custom form. The form presents list of
choices for a
user. In the model the choices are stored single string field
'choices'. But in my
form I wish to present a list of choices and concatenate them together
to save into
the model.
- Hence the model has 'choices'.
- The Form will have choice1, choice2 etc (probably up to several choices).
The code below is simplified with much cruft removed.
In forms.py I have:
class AddDecisionForm(forms.Form):
choice1 = forms.CharField(label='choice1', required=False)
choice2 = forms.CharField(label='choice2', required=False)
enumerated-choices = []
if choice1:
enumerated-choices.append(choice1)
if choice2:
enumerated-choices.append(choice2)
etc....
# Include this here so the form has the field that can be saved to
the model.
choices = forms.CharField(initial='1,2', required=False,
widget=forms.HiddenInput)
def save(self):
d = Decision(**self.cleaned_data)
d.choices = str(enumerated_choices)
d.save()
The above basically outlines "what" I want to do but does not work.
In my views.py I have:
if request.method == 'POST':
if request.POST['submit_action'] == 'Add':
form = AddDecisionForm(request.POST)
if form.is_valid():
form.save()
return HttpResponseRedirect("%s/planner/decision/list/" % root)
else:
# TODO
I'm getting an error when I click Add.
"TypeError at /planner/decision/add/
'choice1' is an invalid keyword argument for this function.
I have read over
http://www.djangoproject.com/documentation/newforms/#custom-form-and-field-validation
and http://www.b-list.org/weblog/2007/nov/23/newforms/
But still having problems working how how to clean this form data. I
understand that I need to probably do some processing in a clean
method to concatenate the choice1 etc values to choices but maybe even
use del self.base_fields['choice1'] etc somehow to remove them from
the form before it validates?
I'm just really confused.
