Mojolicious::Plugin::RESTRoutes - routing helper for RESTful operations


version 1.0.0


This Mojolicious plugin adds a routing helper for RESTful CRUD operations via HTTP to the app.

The routes are intended, but not restricted to be used by AJAX applications.



Can be used to easily generate the needed RESTful routes for a resource.

    my $r = $self->routes;
    my $userroute = $r->rest_routes(name => 'user');

    # Installs the following routes (given that $r->namespaces == ['My::Mojo']):
    #    GET /users                      --> My::Mojo::User::rest_list()
    #   POST /users                      --> My::Mojo::User::rest_create()
    #    GET /users/:userid              --> My::Mojo::User::rest_show()
    #    PUT /users/:userid              --> My::Mojo::User::rest_update()
    # DELETE /users/:userid              --> My::Mojo::User::rest_remove()

Please note: the english plural form of the given name attribute will be used in the route, i.e. "users" instead of "user". If you want to specify another string, see parameter route below.

You can also chain rest_routes:

    $userroute->rest_routes(name => 'hat', readonly => 1);

    # Installs the following additional routes:
    #    GET /users/:userid/hats         --> My::Mojo::Hat::rest_list()
    #    GET /users/:userid/hats/:hatid  --> My::Mojo::Hat::rest_show()

The target controller has to implement the following methods:

  • rest_list

  • rest_create

  • rest_show

  • rest_update

  • rest_remove

Parameters to control the route creation


The name of the resource, e.g. a "user", a "book" etc. This name will be used to build the route URL as well as the controller name (see example above).

readonly (optional)

If set to 1, no create/update/delete routes will be created

controller (optional)

Default behaviour is to use the resource name to build the CamelCase controller name (this is done by Mojolicious::Routes::Route). You can change this by directly specifying the controller's name via the controller attribute.

Note that you have to give the real controller class name (i.e. CamelCased or whatever you class name looks like) including the full namespace.

    $r->rest_routes(name => 'user', controller => 'My::Mojo::Person');

    # Installs the following routes:
    #    GET /users         --> My::Mojo::Person::rest_list()
    #    ...
route (optional)

Specify a name for the route, i.e. prevent automatic usage of english plural form of the name parameter as the route component.

    $r->rest_routes(name => 'angst', route => 'aengste');

    # Installs the following routes (given that $r->namespaces == ['My::Mojo']):
    #    GET /aengste       --> My::Mojo::Angst::rest_list()

How to retrieve the parameters / IDs

There are two ways to retrieve the IDs given by the client in your rest_show, rest_update and rest_remove methods.

Example request: GET /users/5/hats/no9

1. New way: the stash entry fm.ids holds a hash with all ids:

    package My::Mojo::Hats;
    use Mojo::Base 'Mojolicious::Controller';

    sub rest_show {
        use Data::Dump qw(dump);
        print dump($self->stash('fm.ids'));

        # { user => 5, hat => 'no9' }

2. Old way: for each resource there will be a parameter ***id, e.g.:

    package My::Mojo::Hat;
    use Mojo::Base 'Mojolicious::Controller';

    sub rest_show {
        my ($self) = @_;
        my $user = $self->param('userid');
        my $hat = $self->param('hatid');
        return $self->render(text => "$userid, $hatid");

        # text: "5, no9"

Furthermore, the parameter idname holds the name of the last ID in the route:

    package My::Mojo::Hat;
    use Mojo::Base 'Mojolicious::Controller';

    sub rest_show   {
        my $p_name = $self->param('idname');
        my $id = $self->param($p_name);
        return $self->render(text => sprintf("%s = %s", $p_name, $id || ''));

        # text: "hatid = 5"



Adds the routing helper (called by Mojolicious).
