""" 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 formencode.All(OneOf(list), Int())
