=head1 NAME

CatalystX::SimpleLogin::Controller::Login - Configurable login controller


    # For simple useage exmple, see CatalystX::SimpleLogin, this is a
    # full config example
        'Controller::Login' => {
            traits => [
                'WithRedirect', # Optional, enables redirect-back feature
                '-RenderAsTTTemplate', # Optional, allows you to use your own template
            actions => {
                login => { # Also optional
                    PathPart => ['theloginpage'], # Change login action to /theloginpage

See L<CatalystX::SimpleLogin::Form::Login> for configuring the form.


Controller base class which exists to have login roles composed onto it
for the login and logout actions.


=head2 login_form_class

A class attribute containing the class of the form to be initialised. One
can override it in a derived class with the class of a new form, possibly
subclassing L<CatalystX::SimpleLogin::Form::Login>. For example:

    package MyApp::Controller::Login;

    use Moose;


    has '+login_form_class' => (
        default => "MyApp::Form::Login",


=head2 login_form_class_roles

An attribute containing an array reference of roles to be consumed by
the form. One can override it in a similar way to C<login_form_class>:

    package MyApp::Controller::Login;

    use Moose;


    has '+login_form_class_roles' => (
        default => sub { [qw(MyApp::FormRole::Foo MyApp::FormRole::Bar)] },


=head1 METHODS

=head2 BUILD

Cause form instance to be built at application startup.

=head2 do_post_login_redirect

This method does a post-login redirect. B<TODO> for BOBTFISH - should it even
be public? If it does need to be public, then document it because the Pod
coverage test failed.

=head2 login

Login action.

=head2 login_redirect

Redirect to the login action.

=head2 login_GET

Displays the login form

=head2 login_POST

Processes a submitted login form, and if correct, logs the user in
and redirects

=head2 not_required

A stub action that is anchored at the root of the site ("/") and does not
require registration (hence the name).

=head2 redirect_after_login_uri

If you are using WithRedirect (i.e. by default), then this method is overridden
to redirect the user back to the page they initially hit which required

Note that even if the original URI was a post, then the redirect back will only
be a GET.

If you choose B<NOT> to compose the WithRedirect trait, then you can set the
uri users are redirected to with the C<redirect_after_login_uri> config key,
or by overriding the redirect_after_login_uri method in your own login
controller if you need custom logic.

=head2 render_login_form

Renders the login form. By default it just calls the form's render method. If
you want to do something different, like rendering the form with a template
through your view, this is the place to hook into.

=head2 required

A stub action that is anchored at the root of the site ("/") and does
require registration (hence the name).

=head2 remember_me

An action that is called to deal with whether the remember me flag has
been set or not.  If it has been it extends the session expiry time.

This is only called if there was a successful login so if you want a
hook into that part of the process this is a good place to hook into.

It is also obviously a good place to hook into if you want to change
the behaviour of the remember me flag.
