Django wizardview: how to set up step data without validating the form

Question

What I am trying to do I have a view which has a shortcut form which will ask a user to pre-fill some fields before a user is redirected to wizard forms.

For example:

class PreFillView():

    def post(self,request):
        # get the data from the form and save into request.session
        # Then http redirect to the wizard view

Then from this view, I redirect it to a WizardView. In the wizard view, I catch all the information passed in from the previous view in dispatch function:

class MyWizardView(NamedUrlSessionWizardView):
     def dispatch(self,request, *args, **kwargs):
        #parse data from request.session
        #set step data using these data
   # Note these data fields only partially covered the form in the wizardview, there is still a couple of fields needed to be filled in the wizard view. 

This almost works fine but the only problem is that it validates the form and pop up field error for the fields which are not pre-populated. I tried, if I only redirect to the wizard view without setting the step data, it is fine. It won't validate the form, so no field errors will be displayed.

I am pretty new to Django and not sure if I am doing the right thing and if yes, how can I avoid form to be validated after I set the step data for the current step? Any help will be appreciated.

Implement the WizardView.get_form_initial(step) method in you wizard view class.

This method gets step number as parameters and it should return dict for initial data for the form for that step.
