|
5 we can create our own validators
|
|
|
6
|
|
|
7 The table below outlines the options which can be used in a schema in addition to the validators themselves
|
|
|
8 pre_validators [] These validators will be applied before the schema
|
|
|
9 chained_validators [] These validators will be applied after the schema
|
|
|
10 allow_extra_fields False If True, then it is not an error when keys that aren't associated with a validator are present
|
|
|
11 filter_extra_fields False If True, then keys that aren't associated with a validator are removed
|
|
|
12 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.
|
|
|
13 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
