A possible solution is to use prepare itself, this would work both
when validating and when display the form by itself:
class MovieForm(TableForm):
genre_options = [x for x in enumerate((
'Action & Adventure', 'Animation', 'Comedy',
'Documentary', 'Drama', 'Sci-Fi & Fantasy'))]
genre = SingleSelectField(options=genre_options)
def prepare(self):
form_options = getattr(tmpl_context, 'form_options', {})
for c in self.child.children:
c_options = form_options.get(c.key, {})
for name, value in c_options.items():
setattr(c, name, value)
super(MovieForm, self).prepare()
class RootController(BaseController):
@expose('tw2ctest.templates.index')
@validate(MovieForm)
def index(self, **kw):
tmpl_context.form_options = {'genre': {'options':['a', 'b']}}
tmpl_context.form = MovieForm
return dict(page='index')
But I see your point, being able to call .req and alter the widget
would have been a lot easier.
I think that this is just a matter of adding to req the check for
validated_widget as display already does, this would just mean moving
the code from display to req as display calls req itself.
