I was fighting with problem in allowing to redirect user back when using
Form wizard. Here is the use case:
- user1 will choose a login and password in first step, login
availability is checked
- user1 is redirected to second step where he needs to fill up other
important data for creating his account
- meanwhile, user2 registers and takes login of user1
- finally, we got an error when creating the account for user1. here we
need to redirect him to first step and ask him for another login
I wasn't able to find any way how to do this. Finally i was trying to
simulate usage of 'Go back' button, which is defined in
contrib/formtools/wizard/views.py in WizardView.post() method:
{{{#!python
# Look for a wizard_goto_step element in the posted data which
# contains a valid step name. If one was found, render the
requested
# form. (This makes stepping back a lot easier).
wizard_goto_step = self.request.POST.get('wizard_goto_step', None)
if wizard_goto_step and wizard_goto_step in self.get_form_list():
self.storage.current_step = wizard_goto_step
form = self.get_form(
data=self.storage.get_step_data(self.steps.current),
files=self.storage.get_step_files(self.steps.current))
return self.render(form)
}}}
Unfortunately this won't work in final step, becase of resetting the form
wizard in the same file at the end of WizardView.render_done() method:
{{{#!python
done_response = self.done(final_form_list, * *kwargs)
self.storage.reset()
return done_response
}}}
I altered this method to make it work also in final step like this:
{{{#!python
done_response = self.done(final_form_list, **kwargs)
if self.steps.current == self.steps.last:
self.storage.reset()
return done_response
}}}
Do you consider this as a usefull patch which can be included in Django?
Or can you suggest another correct way how to do this?
