[Answered ]-Django Formwizard with dynamic form does not proceed to next step

I discovered what’s going on. The form wizard’s post method calls get_form like so:

        # get the form for the current step
        form = self.get_form(data=self.request.POST, files=self.request.FILES)

        print(form.is_valid(), form.errors, form.is_bound)
        # and try to validate
        if form.is_valid():
            # if the form is valid, store the cleaned data and files.
            self.storage.set_step_data(self.steps.current,
                                       self.process_step(form))
            self.storage.set_step_files(self.steps.current,
                                        self.process_step_files(form))

            # check if the current step is the last step
            if self.steps.current == self.steps.last:
                # no more steps, render done view
                return self.render_done(form, **kwargs)
            else:
                # proceed to the next step
                return self.render_next_step(form)
        return self.render(form)

It only calls the next step’s form if the current form validates, which it never does because my custom get_form hook doesn’t check for the POST data when creating the dynamic form. Anyway here is the working custom get_form hook:

    def get_form(self, step=None, data=None, files=None):
        form = super(EventFormWizard, self).get_form(step, data, files)

        # determine the step if not given
        if step is None:
            step = self.steps.current

        if step == "0":
            loan_sessions = self.request.session.get('loan_sessions', None)
            if loan_sessions != None:
                loan_sessions = pickle.loads(self.request.session['loan_sessions'])
            else:
                loan_sessions = []

            loan_choices = []
            for loan_session in loan_sessions:
                loan_choice = (loan_session['number'], loan_session['name'])
                loan_choices.append(loan_choice)

            ##Pass the data when initing the form, which is the POST
            ## data if the got_form function called during a post
            ## or the self.storage.get_step_data(form_key) if the form wizard
            ## is validating this form again in the render_done method
            form = EventForm1(loan_choices=loan_choices, data=data)

        return form
