""" 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
