NAME

Minima::Controller -- Base class for controllers used with Minima

SYNOPSIS

use Minima::Controller;

my $controller = Minima::Controller->new(
    app => $app,         # Minima::App
    route => $match,     # a match returned by Minima::Router
);
$controller->hello;

DESCRIPTION

Serving as a base class to controllers used with Minima, this class provides the basic infrastructure for any type of controller. It is built around Plack::Request and Plack::Response objects, allowing subclasses to interactly directly with Plack.

Minima::Controller also keeps references to the Minima::App and Plack environment. Additionally, it retains data received from the router, making it readily available to controllers.

This base class is not connected to any view, which is left to methods or subclasses. However, it sets a default Content-Type header for the response as 'text/plain; charset=utf-8' and response code to 200.

CONFIGURATION

The request_encoding key can be included in the main Minima::App configuration hash to specify the expected request encoding. The GET and POST parameters will be decoded based on this setting.

If not set, request_encoding defaults to UTF-8. You may use any encoding value supported by Encode.

METHODS

new

method new (app, route = {})

Instantiates a controller with the given $app reference, and optionally the hash reference returned by the router. If this hash reference contains data extracted from the URI by Minima::Router, then this data will be made available to the controller through the route field.

redirect

method redirect ($url, $code = 302)

Utility method to set the redirect header to the given URL and code (defaults to 302, a temporary redirect) and finalize the response.

Use with return inside other controller methods to shortcut:

# someone shouldn't be here
return $self->redirect('/login');
# continue for logged in users

render

method render ($view, $data = {})

Utility method to call render on the passed view, together with optional data, and save to the response body. Afterward, it returns the finalized response.

EXTRAS

hello, not_found

Methods used to emit a minimal hello, world or not found response.

Returns a plain text printout of the current Plack environment.

dd

method dd ($ref)

Sets the response to text/plain, dumps the passed reference with Data::Dumper, and finalizes the response. Useful for debugging.

return dd($my_data);
