Ah thanks! For a start I was removing the fields from the wrong place.
I really needed to be doing this:
del self.cleaned_data['choice1']

Inelegant. Oh well :-(
But yes I have to consolidate several fields into one in the model.
I now have this:
def clean(self):
enumerated_choices = []
if self.cleaned_data['choice1']:
enumerated_choices.append( (str(self.cleaned_data['choice1']),
int(self.cleaned_data['decision1'])) )
del self.cleaned_data['choice1']
del self.cleaned_data['decision1']
if self.cleaned_data['choice2']:
enumerated_choices.append( (str(self.cleaned_data['choice2']),
int(self.cleaned_data['decision2'])) )
del self.cleaned_data['choice2']
del self.cleaned_data['decision2']
self.cleaned_data['choices'] = str(enumerated_choices)
return self.cleaned_data
def save(self):
d = Decision(**self.cleaned_data)
d.save()
return '%s' % d.id
and it works !
Now it works I have to better understand what's happening and to
iterate over the choices so that it can do any number of fields.
(Basically a user enters a description of a choice and a drop down and
selects a decision. There can be several of these.
The data is turned into a stringified list of tuples and stored in the
database in one string field.)
Thanks Karen for the clue that got it working.
