I have a problem with wizard.

[Olga Burdonova]

I have a problem with wizard, no data from previous forms is stored in session backend ...
What's exactly the problem I do not understand, but as a function called

"def set_step_data(data): ....  self.data[self.step_data_key][step] = cleaned_data"

nothing is stored...

then via pdb I see that _get_data(self):  called instead of _set_data(self, value):

What could be the problem of such behavior?

Backend session is configured ... and I see certain things of wizard database contains ...

for instance:

{'_auth_user_backend': 'allauth.account.auth_backends.AuthenticationBackend', 'wizard_order_wizard': {'step_files': {u'0': {}}, 'step': u'1', 'extra_data': {}, 'step_data': {u'0': {u'csrfmiddlewaretoken': [u'xC8H5GMNDe79iC3jkYAQZUy3E11RhnDK'], u'0-number_of_credits': [u'1'], u'order_wizard-current_step': [u'0']}}}, '_auth_user_id': 1}

but not all steps stored ..

I've tried

SESSION_SAVE_EVERY_REQUEST = True

no results... (very strange behavior..)

What am I doing wrong?

Obviously "done" is not called and wizard stops in render_done

(Pdb) print self.storage.get_step_data(form_key)
None

(Pdb) form_obj.is_valid()
False

return self.render_revalidation_failure(form_key, form_obj, **kwargs)

Does anyone have any idea about this problem?

Solved by overwriting some methods but I still thinking about better solution.

class OrderWizard(SessionWizardView):
    template_name = "order/wizard.html"

    def get_form_key(self, step):
        return "wizard_" + self.prefix + str(step)

    def process_step(self, form):
        self.request.session[self.get_form_key(self.get_step_index())] =  self.get_form_step_data(form)

    def render_done(self, form, **kwargs):
        """
        This method gets called when all forms passed. The method should also
        re-validate all steps to prevent manipulation. If any form don't
        validate, `render_revalidation_failure` should get called.
        If everything is fine call `done`.
        """
        final_form_list = []
        # walk through the form list and try to validate the data again.
        import pdb
        pdb.set_trace()
        for form_key in self.get_form_list():
            form_obj = self.get_form(step=form_key,
                data=self.request.session[self.get_form_key(form_key)],
                files=self.storage.get_step_files(form_key))
            if not form_obj.is_valid():
                return self.render_revalidation_failure(form_key, form_obj, **kwargs)
            final_form_list.append(form_obj)

        # render the done view and reset the wizard before returning the
        # response. This is needed to prevent from rendering done with the
        # same data twice.
        done_response = self.done(final_form_list, **kwargs)
        self.storage.reset()
        return done_response



    def done(self, form_list):
        #form_data = utils.process_form_data(form_list)
        import pdb
        pdb.set_trace()
        return HttpResponseRedirect('/page-to-redirect-to-when-done/')
