Catalyst::Plugin::Params::Profile - Parameter checking with Params::Profile

SYNOPSIS package MyAPP; use Catalyst qw/Params::Profile/;

# In a controller
MyAPP->register_profile(

DESCRIPTION

Catalyst::Plugin::Params::Profile provides a mechanism for a centralised Params::Check or a Data::FormValidater profile. You can bind a profile to a class::subroutine, then, when you are in a subroutine you can simply call $c->check($params) of $c->validate($params) to validate against this profile.

For more information read the manual of Params::Profile , the methods below are just an interface on it.

Public Methods

See Params::Profile for more information about the specific methods, the onse listed below are the most important

$c->register_profile('method' => $METHOD, 'profile' => \%PROFILE);

$c->get_profile('method' => $METHOD);

$c->validate('params' => \%PARAMS);

$c->check('params' => \%PARAMS);

XMLRPC

This module also registers a method name called system.methodHelp into the Server::XMLRPC plugin when it is loaded. This method will try to explain in plaintext the arguments for the subroutine by parsing the given profile.

Example output when system.methodHelp is called with one argument containing the name of the method you'd like to be explained:

Required arguments are:
 * customer_id
 * username
 * product

Optional arguments are:
 * roaming
 * card_type

NOTE: This currently only works for Data::FormValidator profiles.
