=head1 DESCRIPTION |
389
|
|
|
|
|
|
|
|
390
|
|
|
|
|
|
|
C provides an interface to help manage |
391
|
|
|
|
|
|
|
C profiles. |
392
|
|
|
|
|
|
|
|
393
|
|
|
|
|
|
|
I found that I was frequently using C profiles to help |
394
|
|
|
|
|
|
|
define my DB constraints and validation rules, but that depending on the |
395
|
|
|
|
|
|
|
context I was working in I may only be manipulating a small handful of the |
396
|
|
|
|
|
|
|
fields at any given point. Although I could query my DB layer to get the |
397
|
|
|
|
|
|
|
default validation profile, I was really only concerned with the rules for two |
398
|
|
|
|
|
|
|
or three fields. Thus, C, to help make it easier |
399
|
|
|
|
|
|
|
to trim profiles to include only certain sets of fields in the profile. |

All said, though, C has some limitations that you |
404
|
|
|
|
|
|
|
need to be aware of. |

It B removes fields from the following profile attributes: |
411
|
|
|
|
|
|
|
|
412
|
|
|
|
|
|
|
required |
413

|
|
optional |

B effort is made to update dependencies, groups, require_some, or anything |
420
|
|
|
|
|
|
|
based on a regexp match. Yes, that does mean that this module is limited in |
421
|
|
|
|
|
|
|
its usefulness if you've got really fancy C profiles. |
422
|
|
|
|
|
|
|
That said, though, I'm not using anything that fancy, so it works for me. |

To use the profile with C, use either the form of: |
427
|
|
|
|
|
|
|
|
428
|
|
|
|
|
|
|
$profile->check($data) |
429
|
|
|
|
|
|
|
|
430
|
|
|
|
|
|
|
or |
431
|
|
|
|
|
|
|
|
432
|
|
|
|
|
|
|
Data::FormValidator->check($data, $profile->profile) |
433
|
|
|
|
|
|
|
|
434
|
|
|
|
|
|
|
C won't accept a blessed object when calling |
435
|
|
|
|
|
|
|
Ccheck()>, so you need to call |
436
|
|
|
|
|
|
|
C<$profile-Eprofile()> to turn the |
437
|
|
|
|
|
|
|
profile into a HASHREF first. |
438
|
|
|
|
|
|
|
|
439
|
|
|
|
|
|
|
Unless you're doing anything fancier and you've got an actual |
440
|
|
|
|
|
|
|
C object that you're working with, its easier/simpler to |
441
|
|
|
|
|
|
|
just call C<$profile-Echeck($data)>; that's the recommended interface. |
