I finally hit upon a solution. I'm using the SessionWizardView class in Django 1.4. I overrode the render_done() function (copied it directly out of django/django/contrib/formtools/wizard/views.py and tweaked it. Between 'final_form_list.append(form_obj)' and the last three lines (starting with 'done_response = self.done(final_form_list, **kwargs)') I handle talking with the payment gateway. If there's an error, I redirect back to the last step in the form (using self.render.revalidation_failure()) and they can try again. Here's a snippet of code: <pre><code>try: charge = stripe.Charge.create( amount=price_in_cents, currency="usd", card=token, description="BlahStore Order Number: %s" %(self.order.pk), ) except (stripe.APIConnectionError, stripe.APIError, stripe.AuthenticationError, stripe.CardError, stripe.InvalidRequestError, stripe.StripeError) as e: from django.forms import forms from django.forms.util import ErrorList errors = final_form_list[3]._errors.setdefault(forms.NON_FIELD_ERRORS, ErrorList()) errors.append(e.message) return self.render_revalidation_failure(3, final_form_list[3], **kwargs) </code></pre> You'll notice I have '3' hard-coded in a few places--this is because my wizard has four steps and the array is zero based. I set the error message to display and then redirect. I'm sure it would be fairly easy to adapt this if you wanted to stick with process_step(), but I personally think TheRightWay is to override the render_done() function.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
