Can someone post exact details of how they have

Answer 1

The as_view function converts a class based view into a callable view:

myapp/views.py

from django import forms
from django.contrib.auth.decorators import login_required
from django.contrib.formtools.wizard.views import SessionWizardView
from django.template.response import TemplateResponse

class Form1(forms.Form):
    a = forms.CharField()

class Form2(forms.Form):
    b = forms.CharField()

FORMS = [("step1", Form1),
         ("step2", Form2)]

TEMPLATES = {"step1": "wizard_step.html",
             "step2": "wizard_step.html"}

class MyWizard(SessionWizardView):

    def get_template_names(self):
        return [TEMPLATES[self.steps.current]]

    def done(self, form_list):
        # get data from forms
        a = self.get_cleaned_data_for_step('step1')['a']
        b = self.get_cleaned_data_for_step('step2')['b']
        # access the request as self.request
        request = self.request
        # (...)
        # return response
        return TemplateResponse(request, 'wizard_success.html', {
            'a': a,
            'b': a
        })

wizard_view = MyWizard.as_view(FORMS)

@require_login
def wrapped_wizard_view(request):
    return wizard_view(request)

myapp/templates/wizard_step.html

{% extends "base.html" %}
{% load i18n %}

{% block content %}

<form method="post">
{% include "formtools/wizard/wizard_form.html" %}
</form>

{% endblock %}

myapp/urls.py

from django.conf.urls import patterns, url

urlpatterns = patterns('myapp.views',
    url(r'^wizard/$', 'wrapped_wizard_view'),
)

An alternative answer - instead of wrapping your view you could always use a decorator on your Wizardview class, as described in the documentation

You would therefore do the following imports:

from django.contrib.auth.decorators import login_required
from django.utils.decorators import method_decorator

and then within class createObjectWizard(SessionWizardView) you would add the following:

 @method_decorator(login_required)
 def dispatch(self, *args, **kwargs):
     return super(createObjectWizard, self).dispatch(*args, **kwargs)

this way you don't have to mess with urls.py - it's all taken care of within the view. Hope this helps
