SYNOPSIS


package MyApp;
use Moose;
use namespace::autoclean;
use Catalyst qw/
+CatalystX::SimpleLogin
Authentication
Session
Session::State::Cookie
Session::Store::File
/;

'Plugin::Authentication' => { # Auth config here }
);
__PACKAGE__->config(
'Controller::Login' => { # SimpleLogin config here }
);
__PACKAGE__->setup;

ATTENTION!

If you're new here, you should start by reading CatalystX::SimpleLogin::Manual, which provides a gentler introduction to using this code. Come back here when you're done there.

DESCRIPTION

CatalystX::SimpleLogin is an application class Moose::Role which will inject a Catalyst::Controller which is an instance of CatalystX::SimpleLogin::Controller::Login into your application. This provides a simple login and logout page with the adition of only one line of code and one template to your application.

REQUIREMENTS

A Catalyst application
Working authentication configuration
Working session configuration
A view

CUSTOMISATION

CatalystX::SimpleLogin is a prototype for CatalystX::Elements. As such, one of the goals is to make it easy for users to customise the provided component to the maximum degree possible, and also, to have a linear relationship between effort invested and level of customisation achieved.

Three traits are shipped with SimpleLogin: WithRedirect, Logout, and RenderAsTTTemplate. These traits are set in the config: 

   __PACKAGE__->config(
        'Controller::Login' => {
            traits => [qw/ Logout WithRedirect RenderAsTTTemplate /],
            login_form_args => { # see the login form },
   );

COMPONENTS

  • CatalystX::SimpleLogin::Controller::Login - first point of call for customisation. Override the action configs to reconfigure the paths of the login or logout actions. Subclass to be able to apply method modifiers to run before / after the login or logout actions or override methods.
  • CatalystX::SimpleLogin::TraitFor::Controller::Login::Logout - provides the "logout" action and associated methods. You can compose this manually yourself if you want just that action.

    This trait is set by default, but if you set another trait in your config, you will have to include it.

  • CatalystX::SimpleLogin::TraitFor::Controller::Login::WithRedirect - provides the "login" action with a wrapper to redirect to a page which needs authentication, from which the user was previously redirected. Goes hand in hand with Catalyst::ActionRole::NeedsLogin
  • CatalystX::SimpleLogin::TraitFor::Controller::Login::RenderAsTTTemplate - sets the stash variable 'template' to point to a string reference containing the rendered template so that it's not necessary to have a login.tt template file.
  • CatalystX::SimpleLogin::Form::Login - the HTML::FormHandler form for the login form.
  • Catalyst::ActionRole::NeedsLogin - Used to cause a specific path to redirect to the login page if a user is not authenticated.

TODO

Here's a list of what I think needs working on, in no particular order.

Please feel free to add to or re-arrange this list :)

Fix extension documentation
Document all this stuff.
Examples of use / customisation in documentation
Fixing one uninitialized value warning in LoginRedirect
Disable the use of NeedsLogin ActionRole when WithRedirect is not loaded
