I'm able to get validation working with widgets without too much
difficulty, but, I need to write my own validation handler along with
using the FieldsMatch chained_validator which I'm having some
difficulty with.
models:
class PasswordSchema(Schema):
oldpassword = String(not_empty=True)
password = String(not_empty=True)
passwordverify = String(not_empty=True)
chained_validators = [FieldsMatch
('password','passwordverify')]
class PasswordForm(TableForm):
action = 'passwordsave'
class fields(WidgetsList):
oldpassword = PasswordField(validator=NotEmpty)
password = PasswordField(validator=NotEmpty)
passwordverify = PasswordField(validator=NotEmpty)
controller code:
@expose('cp.templates.template')
def password(self, **kw):
c.form = PasswordForm()
return dict(value=dict(), template='form')
#...@validate(PasswordForm(), error_handler=password)
@validate(PasswordSchema())
def passwordsave(self, **kw):
if c.form_errors:
flash("There was an error")
print c.form_errors
else:
#provider.edit('clients',values=kw)
flash("Password updated")
redirect('password')
If I use validate(PasswordForm(), error_handler=password), errors are
correctly diagnosed and output to the rendered handler, password.
Empty values display 'Please enter a value' next to each of the
fields.
If I switch to the PasswordSchema() validation, I am able to read the
debug log and see
{'password': 'Please enter a value', 'oldpassword': 'Please enter a
value', 'passwordverify': 'Please enter a value'}
where it printed c.form_errors, however, I am not able to rerender the
password template. If I change my validate decorator to:
@validate(PasswordSchema(), error_handler=password)
TurboGears does understand there was an error, but redisplays the
password template without having displayed the error messages.
What am I doing wrong?
