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.
