Well, not exactly. The thing you have to remember with chained
validators is to set the error message dict yourself, otherwise the
validation error will show up next to _each_ field:
class MyCustomValidator(validators.FancyValidator):
messages = {
'foo': 'Foo made a boo boo"
}
def validate_python(self, value, state):
if not some_check(value):
message = self.message('notUnique2', state)
# are we called as a chained validator?
if isinstance(value, dict):
errors = dict(url=message)
raise validators.Invalid(message, value, state,
error_dict=errors)
raise validators.Invalid(message, value, state)
