I'm desperate here. I'm having serious problems with the form
wizard.
In url.py I have:
url(r'refinance/$', RefinanceWizard([RefinanceForm_1,
RefinanceForm_2, DummyForm, DummyForm]), name='refinance'),
So you can see that I have 4 steps. The purpose of the DummyForm is
just a place holder. They will be substituted depending on responses
within earlier steps. So here's the process_step code for the wizard:
def process_step(self, request, form, step):
if isinstance(form, RefinanceForm_2) and
form.__dict__.has_key('cleaned_data'):
if form.cleaned_data['other_investments'] == 'Y':
self.form_list[2] = RefinanceForm_3_yes
else:
self.form_list[2] = RefinanceForm_3_no
if isinstance(form, (RefinanceForm_3_yes, RefinanceForm_3_no))
and form.__dict__.has_key('cleaned_data'):
if form.cleaned_data['mortgage_count'] == '1' or
form.cleaned_data['mortgage_count'] == 1:
self.form_list[3] = RefinanceForm_4_1
else:
self.form_list[3] = RefinanceForm_4_2
So, some notes... I am using "Y/N" to represent bool values, because
that was broken a few weeks ago and I don't know if I should switch
back to bool values yet (should I - do they work now!?!)
Now the cleaned_data... You'll notice that I test for a string and an
integer. I found that using an integer (xxxx = 1 instead of xxxx =
'1') was NEVER triggered so I always went to the else and
RefinanceForm_4_2 was added.
I thought one of the points of cleaned_data is that the value gets
normalized back to the proper data type. If this field is an
IntegerField in my model/form, which it is, this should be an integer
when I access the value in cleaned_data. Correct?
So, the problems I am seeing, which happen very sporadically, are:
1. When step 4 is submitted (the last step), I get an traceback
telling me DummyForm has no save method, mind you, everything up to
and including the last step seemed to have worked fine and I already
substituted all the dummy forms with the proper ones.
2. When I submit RefinanceForm_3, and look at the value of
mortgage_count, I'll often get a blank RefinanceForm_4, which I'm
assuming is the DummyForm that is actually being shown. This will
also happen on occasion where RefinanceForm_3 is not displayed and the
DummyForm does.
Its to the point where I document every value I enter, for ~40 fields,
and try to recreate the problem. Sometimes it works and sometimes it
doesn't. I don't know where its failing - maybe the hashing and
validating stuff in the wizard?? No exceptions are getting raised...
I'm not even sure I'm using the process_step function correctly, as
there's no samples in the documentation...
Suggestions?
