Over ride the post method of your wizard class. There you can call
get_all_cleaned_data or get_cleaned_data_for_step. Use the default
implementation and adjust it to work according to you logic. From your post
method you can raise ValidationError but it will crash the app. If you want
the normal form behavior where ValidationError will render the form with
the error at the top, you will need to do that in your form's clean method.

More details on the form and why there is a field that depends on 6 pages:
In steps 2-5, I am prompting the user for questions and choices about a
particular service.
On page 6 they are given the opportunity to select a date/time for the
service. The validation will calculate how how much time is required based
on steps 2-5 and see if the time they pick fits in the calendar. If it
doesn't, it will ask them to pick a different time.
I'm still not sure where I can use it, because I can't call
get_cleaned_data_for_step from the forms validation/clean field, and I'm
not sure where else I can access the required form steps and also be able
to raise a validation error.

Hi,
You can use the wizard's get_cleaned_data_for_step(step) method where step
is 0-indexed so step 2 form data would be:
get_cleaned_data_for_step('1').
It would return a dictionary of the cleaned data for that step.
Ignorable comment: I would be very pissed if I had to fill 6 form pages
only to be told I can't continue because of something I did 4 pages ago.

Hello,
I am using FormWizard with a 12-step form.
On step 6, I want to perform verification on a field but it depends on
fields that were entered in steps 2-5.
I cannot figure out how to get data from the previous steps in the form
validation for step 6.
Where is a point in the FormWizard where I can access previous form data
and can also raise ValidationError on a field?
Thanks,
