""" this is forms validation classes http://formencode.org/module-formencode.validators.html for list off all availible validators we can create our own validators The table below outlines the options which can be used in a schema in addition to the validators themselves pre_validators [] These validators will be applied before the schema chained_validators [] These validators will be applied after the schema allow_extra_fields False If True, then it is not an error when keys that aren't associated with a validator are present filter_extra_fields False If True, then keys that aren't associated with a validator are removed if_key_missing NoDefault If this is given, then any keys that aren't available but are expected will be replaced with this value (and then validated). This does not override a present .if_missing attribute on validators. NoDefault is a special FormEncode class to mean that no default values has been specified and therefore missing keys shouldn't take a default value. ignore_key_missing False If True, then missing keys will be missing in the result, if the validator doesn't have .if_missing on it already <name> = formencode.validators.<name of validator> <name> must equal form name list=[1,2,3,4,5] for SELECT use
