Using Django FormWizard in a view

I recently needed to use a Django form wizard from a view. I needed it in a view as I had some permissions that I needed to check and also wanted to supply some initial data as the form would now be editing information that was previously supplied.

I had found some code on Django Snippets but it was also messing around with the way that form wizards were defined. I didn’t want to change the way that form wizards behaved so I stripped out the changes and was left with a minimal way to use a form wizard in a view.

The main thing to notice is that first you have to create an instance of the FormWizard. Then as the object to return from the view you must call the instance passing through the context and the request.

Example:

@login_required
def edit_form_wizard(request, slug):
    # Do some permission checking
    ..... snip .....

    # Set up the dictionary of initial data for the form
    # In this case, we are pre-filling some data from the first form only
    initial = {0: {'first_name': request.user.first_name,
                   'last_name': request.user.last_name,
                   'email': request.user.email,
                  },
              }

    # Create the form wizard
    form = EditFormWizard([ContactForm, SecondForm, ThirdForm], initial=initial)

    # Call the form wizard passing through the context and the request
    return form(context=RequestContext(request), request=request)
