NAME

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

SYNOPSIS

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

    # In a controller
    MyAPP->register_profile(
                    'method'    => 'subroto',
                    'profile'   => {
                                testkey1 => { required => 1 },
                                testkey2 => {
                                        required => 1,
                                        allow => qr/^\d+$/,
                                    },
                                testkey3 => {
                                        allow => qr/^\w+$/,
                                    },
                                },
                );

    sub subroto : Private {
        my (%params) = @_;

        return unlesss $c->validate('params' => \%params);
        ### OR
        my %opts = $c->check_params or return;

        ### DO SOME STUFF HERE ...

        my $profile = $c->get_profile('method' => 'subroto');
    }


    ### Multiple Profile
    MyAPP->register_profile(
                    'method'    => 'subalso',
                    'profile'   => [
                                    'subroto',
                                    {
                                    testkey4 => { required => 1 },
                                    testkey5 => {
                                            required => 1,
                                            allow => qr/^\d+$/,
                                        },
                                    testkey6 => {
                                            allow => qr/^\w+$/,
                                        },
                                    },
                                ],
                );


    sub subalso : Local {
        my (%params) = @_;

        ### Checks parameters agains profile of subroto and above registered
        ### profile
        return unlesss $c->validate('params' => \%params);

        ### DO SOME STUFF HERE ...
    }

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);

$c->check_params;

Checks $c->req->params against the profile of the calling sub. It returns a HASHREF containing validate parameters, or undef on failure. It will also log to Catalyst::Log about what happened.

Extra options to this sub are:

params OPTIONAL

Validate against params instead of $c->req->params

profile OPTIONAL

Validate against profile instead of profile of calling sub

allow_unknown OPTIONAL

Pass the unknown parameters to the return HREF rather than filtering them out.

dv OPTIONAL

Instead of returning a hashref containing validated params, return the Data::FormValidator::Results object.

NOTE: Only tested with Data::FormValidator yet!!

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.
