It's a good path, but you misunderstan something about callbacks in
validate.
You do *not* call get_form in the validate, but pass it as reference:
@validate(form=get_form)
Then in get_form, you can e.g. inspect the request to have a look at a
hidden form value you pass for distinction:
def get_form():
if cherrypy.request.params.get('formtype') == "complex":
return complex_form
return simple_form
The above code is untested, and has two uncertainties:
- I don't know if that's the way to get to the actual request params
- but something like that for sure works.
- I don't know if get_form get's passed anything - if in doubt,
capture with *args or such.
