NAME

       Catalyst::Action::Deserialize - Deserialize Data in a Request

SYNOPSIS

           package Foo::Controller::Bar;

           __PACKAGE__->config(
               'default'   => 'text/x-yaml',
               'stash_key' => 'rest',
               'map'       => {
                   'text/x-yaml'        => 'YAML',
                   'text/x-data-dumper' => [ 'Data::Serializer', 'Data::Dumper' ],
               },
           );

           sub begin :ActionClass('Deserialize') {}

DESCRIPTION

       This action will deserialize HTTP POST, PUT, OPTIONS and DELETE requests.  It assumes that
       the body of the HTTP Request is a serialized object.  The serializer is selected by
       introspecting the requests content-type header.

       If you want deserialize any other HTTP method besides POST, PUT, OPTIONS and DELETE you
       can do this by setting the "deserialize_http_methods" list via "action_args".  Just modify
       the config in your controller and define a list of HTTP methods the deserialization should
       happen for:

           __PACKAGE__->config(
               action_args => {
                   '*' => {
                       deserialize_http_methods => [qw(POST PUT OPTIONS DELETE GET)]
                   }
               }
           );

       See also "action_args" in Catalyst::Controller.

       The specifics of deserializing each content-type is implemented as a plugin to
       Catalyst::Action::Deserialize.  You can see a list of currently implemented plugins in
       Catalyst::Controller::REST.

       The results of your Deserializing will wind up in $c->req->data.  This is done through the
       magic of Catalyst::Request::REST.

       While it is common for this Action to be called globally as a "begin" method, there is
       nothing stopping you from using it on a single routine:

          sub foo :Local :Action('Deserialize') {}

       Will work just fine.

       When you use this module, the request class will be changed to Catalyst::Request::REST.

CUSTOM ERRORS

       For building custom error responses when de-serialization fails, you can create an
       ActionRole (and use Catalyst::Controller::ActionRole to apply it to the "begin" action)
       which overrides "unsupported_media_type" and/or "serialize_bad_request" methods.

SEE ALSO

       You likely want to look at Catalyst::Controller::REST, which implements a sensible set of
       defaults for a controller doing REST.
