Generic Form Controller

[Ed Singleton]

With a lot of help from Alberto, I've created a Generic Form
Controller that reduces a lot of the repetition when you have lots of
straightforward forms on your site. It should be fairly easy to
customise for your own purposes:

class GenericFormController(controllers.Controller):
def __init__(self, form, data_handler, intro_text="",
thank_you_message="Thank you."):
super(self.__class__, self).__init__()
self.form = form
self.data_handler = data_handler
self.intro_text = intro_text
self.thank_you_message = thank_you_message

@expose()
@validate(form=self.form)
@error_handler(self.index.im_func)
def save(self, **kwargs):
self.data_handler(**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_message = self.thank_you_message
return dict(thank_you_message=thank_you_message)

It can be used like this:

register = GenericFormController(my_form, model.MyTable,
intro_text='Please fill in my form.', thank_you_message='Thank you for
filling in my form.')

Hope it's of use to people.

This should be saved somewhere so it doesn't get diluted in the
flood... :)

Is the Trac still the place to post recipes like this one?

No, the RoughDocs[1] area of the docs site is the place for recipes
like this now.

I tag posts like this to prevent this from happening. Eventually I'll
move the tagged posts to the wiki, but it's always nice when somebody
else does it for me. ;]

How do you tag posts? Are you the one using the google "rate this
post" option, or are you doing something in your email client or
something? Just curious!

I read this list through gmail, which does support labels. I use an
expanded set of keyboard shortcuts [1], which means I don't have to
pick it from the menu and makes using labels as tags a bit simpler.

I'll pop it in myself over the next couple of days.
