Laravel 4: Confused about how to use App::make()

问题

I am trying to follow the repository pattern outlined in this article http://code.tutsplus.com/tutorials/the-repository-design-pattern--net-35804#highlighter_174798 And I am trying to instantiate a class in Laravel using App::make() (Which I am guessing is Laravel's factory pattern?) and I am trying to parse arguments to my class but I can't work out how to do it.

Code:

namespace My;

class NewClass {
    function __construct($id, $title) 
    {
        $this->id = $id;
        $this->title = $title;
    }
}

$classArgs = [
    'id'    => 1,
    'title' => 'test',
]

$newClass = App::make('My\NewClass', $classArgs);

Can anyone point to an example of how to use App::make() or have I gone in the completely wrong direction and shouldn't be using App::make()?

App is actually a facade for Laravel IoC container usually used for automatic resolution. Understanding of IoC concept is vital for complex application development but small projects will benefit from well architecture for sure. I would recommend to dive into Laravel documentation first and try some examples on Service Providers, Bindings and Automatic Resolution.

Speaking about your example:

namespace My;

class NewClass {

    function __construct($id, $title) 
    {
        $this->id    = $id;
        $this->title = $title;
    }
}


$newClass = App::make('My\NewClass', [1, 'test']);

The good people in the Laravel forum answered this one for me http://laravel.io/forum/02-10-2014-laravel-4-confused-about-how-to-use-appmake

Pretty much if you can bind custom instantiation code with App::bind(); like so

App::bind('My\NewClass', function() use ($classArgs) {
    return new My\NewClass($classArgs['id'], $classArgs['title']);
});

// get the binding
$newClass = App::make('My\NewClass');
