The very minimal controller you need to do the ToscaWidgets movie
tutorial is:
from pylons import request, response, session, tmpl_context
from tw.mods.pylonshf import validate
import tw.forms as twf
from cp.lib.base import BaseController, render
movie_form = twf.TableForm('movie_form', action='save', children=[
twf.HiddenField('id'),
twf.TextField('title'),
twf.TextField('year', size=4),
twf.CalendarDatePicker('release_date'),
twf.SingleSelectField('genera', options=['', 'Action', 'Comedy',
'Other']),
twf.TextArea('description', validator=twf.validators.NotEmpty),
])
class TestController(BaseController):
def index(self):
tmpl_context.form = movie_form
return render('/movie.mako')
@validate(movie_form, error_handler='index')
def save(self, **kw):
return str(kw)
and movie.mako would contain:
${tmpl_context.form()|n}
Example taken from:
http://toscawidgets.org/documentation/tw.forms/tutorials/index.html
The page:
http://toscawidgets.org/documentation/tw.forms/tutorials/validate_pylons.html
contains an error in the validate string which is missing the quotes
around the error_handler.
@validate(form=movie_form, error_handler=index)
should be replaced with:
@validate(form=movie_form, error_handler='index')
