Question

我有两张这样的表：

users: users_id | name | users_roles_id

users_roles: users_roles_id | roles

我想加入这些表格。我尝试过以下方法：

use Elegant\Model as Eloquent;

class User extends Eloquent {
    protected $table = 'users';

    function getRoles($userId){
        User::join('users_roles', 'users_roles.users_roles_id', '=', 'users.users_roles_id')
            ->select('*')
            ->get();    
    }

    public function user_role() {
        return $this->belongsTo('users_roles','users_roles_id');
    }
}

但我不知道如何加入这些来展示它。感谢

Answer 1

尝试替换此

object?

使用

return $this->belongsTo('users_roles', 'users_roles_id');

阅读更多Eloquent Laravel文件，名称方便

Answer 2

我做了

    class User extends Eloquent {
        protected $table = 'users';

        function getRoles($userId){
            return $this->where('id', $userId)->join('users_roles', 'users.users_roles_id = users_roles.users_roles_id')->get();  
        }
    }

它正在运作; - ）

您创建

芯/ MY_Model.php

<?php

require_once FCPATH . 'filelocation/Eloquent.php';

class MY_Model extends Eloquent {

    public function __construct() {
       parent::__construct();
    }

}

然后在模型上

模型＆gt; User_model.php

<?php 

class User_model extends MY_Model {
   public function __construct() {
       parent::__construct();
    }
}

Codeigniter Eloquent查询关系
