Yes that did it. I had to do a log.debug(dir(self.index)) to be
really sure that you meant self.index.im_func as I'd never heard of
im_func before.
The solution below works fine except for the redirect to the thank you
page. I have to stop now but I'll play some more tomorrow. I'll
probably fix it by adapting Matthew's single form controller so that
there isn't a redirect.
**If anyone else wants to use this controller, a quick warning to note
that I add a save() method to my tables that mangles my data for me.
You may want to change it to read table(**kwargs)
class FormController(controllers.Controller):
def __init__(self, form, table, intro_text="", thank_you="Thank you."):
super(FormController, self).__init__()
self.form = form
self.table = table
self.intro_text = intro_text
self.thank_you = thank_you
@expose()
@validate(form=self.form)
@error_handler(self.index.im_func)
def save(self, **kwargs):
table.save(**kwargs)
raise redirect('thank_you')
self.save = new.instancemethod(save, self, self.__class__)
@expose(template='.templates.form')
def index(self):
form = self.form
intro_text = self.intro_text
return dict(form=form, intro_text=intro_text)
@expose(template='.templates.form_thankyou')
def thank_you(self):
thank_you = self.thank_you
return dict(thank_you=thank_you)
