问题 TL;DR Can you limit an Eloquent ORM query like using take() and skip() so that the resulting mysql query is also limited, and it doesn't have to return the entire dataset? If so, how would you modify: $test = User::find(1)->games->toArray(); To include limit 3 offset 2 ? Tables: users games userGames -- id -- id -- user_id -- name -- name -- game_id -- steam_id Models: class User extends Eloquent { public function games() { return $this->belongsToMany('Game', 'userGames', 'user_id', 'game_id'

问题 I'm developing some kind of RESTful API. When some error occurs, I throw an App::abort($code, $message) error. The problem is: I want him to throw a json formed array with keys "code" and "message", each one containing the above mentioned data. Array ( [code] => 401 [message] => "Invalid User" ) Does any one knows if it's possible, and if it is, how I do it? 回答1: go to your app/start/global.php . This will convert all errors for 401 and 404 to a custom json error instead of the Whoops

问题 I get a bit confused over all the nice things laravel has to offer in terms of the IOC container and facades. Since I'm not an experienced programmer it gets overwhelming to learn. I was wondering, what is the difference between these two examples: A facade to 'Foo' and registered in the container via App::bind() A facade to 'Foo' and registered in the container via App::singleton() In my best understanding Foo::method() will be rewritten as $app->make['foo']->method() so in the first example

问题 Is there a way to see the old/previous value of a model's attribute in its saving or updating event? eg. Is something like the following possible: User::updating(function($user) { if ($user->username != $user->old->username) doSomething(); }); 回答1: Ok, I found this quite by chance, as it's not in the documentation at present... There is a getOriginal() method available which returns an array of the original attribute values: User::updating(function($user) { $original = $user->getOriginal();

问题 I know there's a way to create versioned URLs for REST APIs with routes, but what's the best way to organize controllers and controller files? I want to be able to create new versions of APIs, and still keep the old ones running for at least some time. 回答1: I ended up using namespaces and directories under app/controllers: /app /controllers /Api /v1 /UserController.php /v2 /UserController.php And in UserController.php files I set the namespace accordingly: namespace Api\v1; or namespace Api

问题 I am new to using Laravel, and Homestead, and would appreciate any help or a point in the right direction. I have successfully been able to get to the "You have arrived" screen when I run "php artisan serve" but when I try to do the same thing via Vagrant, I get "no input file specified".
