.. _validate_tg1:

TurboGears 1
------------

Add the following to ``myapp/controllers.py``, inside the ``Root`` class::

    @expose()
    @tg.validate(form=movie_form)
    @tg.error_handler(movie)
    def save_movie(self, **kw):
        return str(kw)

Also, update the existing ``movie`` method, change::

    def movie(self):

to::

    def movie(self, **kw):

We also need to update the form definition a little. Add this before the definition::

    class FilteringSchema(twf.validators.Schema):
        filter_extra_fields = True
        allow_extra_fields = True

And change::

    movie_form = twf.TableForm('movie_form', action='save_movie', children=[

To::

    movie_form = twf.TableForm('movie_form', action='save_movie',
        validator=FilteringSchema, children=[
