Not sure whether it is more elegant or not, but here goes:
As I understand it, the wizard-class contains an extra_context that
automatically gets handed to the templates. You can modify the
extra_context in the process_step-method, allowing you to add
additional information for each step you go through. Also, as I
understand it, the process_step-method is given a cleaned (correct)
form for the current step, so you can extract information from that
form and put it into the extra_context.
Thus, you could do something like (no changes to get_template):
class EnrollWizard(FormWizard):
def process_step(self, request, form, step):
if step == 0:
self.extra_context['foo'] = form.cleaned_data['foo']
elif step == 1:
self.extra_context['bar'] = form.cleaned_data['bar']
elif step == 3:
self.extra_context['baz'] = form.cleaned_data['baz']
Now, in each template you will have access to more and more additional
information, just like so:
{{ foo }}
{{ bar }}
{{ baz }}
I am not sure exactly how this maps to your example (as I do not fully
understand it), but maybe it could simplify things slightly for you?
Now, if someone could point me to a simple way of combining form
wizards with formsets, my day would be complete... :-)
