Lukasz Lenart updated WW-4340:
------------------------------
Fix Version/s: 7.0.0
(was: 6.1.0)
> Grouping same type validators
> -----------------------------
>
> Key: WW-4340
> URL: https://issues.apache.org/jira/browse/WW-4340
> Project: Struts 2
> Issue Type: Improvement
> Components: XML Validators
> Reporter: Antonio Sánchez
> Priority: Minor
> Labels: validation
> Fix For: 7.0.0
>
>
> In a middle sized application there may be hundreds of required fields, and
> maybe dozens of some other validator type, which are all very verbose to
> define.
> For instance: guess a big form with many required fields:
> {code:xml}
> <validator type="requiredstring">
> <param name="fieldname">person.firstName</param>
> <message>First name is required.</message>
> </validator>
> <validator type="requiredstring">
> <param name="fieldname">person.lastName</param>
> <message>Last name is required.</message>
> </validator>
> ... same for age...
> ... same for manymore...
> {code}
> This is repeating the same pattern for both defining the validator and the
> corresponding message.
> It would be great to have an abbreviated syntax, for instance
> (pseudo-language):
> {code}
> <validator type="requiredstring">
> <param name="fieldname">person.lastName, person.lastName, person.age,
> person.manymore</param>
> <message>[MATCHED_FIELDNAME] is required.</message>
> </validator>
> {code}
> or
> {code:xml}
> <validator type="requiredstring">
> <param name="fieldname">person.lastName, person.lastName, person.age,
> person.manymore</param>
> <message key="requiredField" />
> </validator>
> {code}
> and 'global_validation_messages.properties' having
> {noformat}
> requiredField = [MATCHED_FIELDNAME] is required.
> {noformat}
> Not only "required" validator, but any other one.
> Advantages:
> 1. Message is defined once. It is easy to uniformly change 'Field is
> required' to 'Please, fill this field".
> 2. Define affected fields all in a row. If my form has 10 required field,
> then 10 validation definitions are currently needed. With this improvement,
> only 1 definition is needed.
