Question

我跟着this tutorial让Laravel的Eloquent在现有的Codeigniter项目中运行，一切正常，直到我尝试使用Eloquent的关系。这是我的违规代码：

class Announcement_model extends Eloquent {
    protected $table = 'announcements';
    public function game() {
        $this->load->model('game_model');
        return $this->belongsTo('Game_model', 'game_id');
    }
}

class Game_model extends Eloquent {
    protected $table = 'games';    
}

控制器：

class Api_announcement extends REST_Controller {
    ...
    public function index_get() {
        $response = Announcement_model::with('game')->get();
        $this->response(array('error'=> false, 'response' => $response), 200);
    }
}

我遇到了这个错误：

<b>Fatal error</b>:  Uncaught exception 'LogicException' with message 'Relationship method must return an object of type Illuminate\Database\Eloquent\Relations\Relation' in myproject\vendor\illuminate\database\Eloquent\Model.php:2695

#5 [internal function]: Illuminate\Database\Eloquent\Builder-&gt;Illuminate\Database\Eloquent\{closure}()
#6  in 
<b>myproject\vendor\illuminate\database\Eloquent\Model.php</b> on line 
<b>2695</b>

我做错了什么？我上下寻找解决方案，但没有任何效果。

Answer 1

return $this->belongsTo('Game_model', 'game_id')->select(array('name'));

以数组形式返回，但没有关系。你需要这个：

return $this->belongsTo('Game_model', 'game_id');

在Codeigniter中使用Eloquent，我在设置关系时遇到了麻烦
