ArcheTypes:validatorのメモ
コンテンツのクラスに validate_foo(newvalue) というメソッド(fooはフィールド名)を作っておくと、勝手に呼び出してくれます。やってくれるお利口さんは、Products.ArcheTypes.BaseObject.BaseObject.validate_fieldメソッドさんです。
def validate_field(self, name, value, errors):
"""Field's validate hook.
Write a method: validate_foo(new_value) -> "error" or None
If there is a validate method defined for a given field invoke
it by name
name -- the name to register errors under
value -- the proposed new value
errors -- dict to record errors in
"""
methodName = "validate_%s" % name
result = None
if shasattr(self, methodName):
method = getattr(self, methodName)
result = method(value)
if result is not None:
errors[name] = result
return result
