Model 使用laravel 5.3中的雄辩连接两个模型

我有两张桌子

用户表格：

 id (integer)
 name (string)
 email (string)
 phone (string)
 codeMeli (string)

userId (integer)
adminId (integer)

和用户管理表格：

 id (integer)
 name (string)
 email (string)
 phone (string)
 codeMeli (string)

userId (integer)
adminId (integer)

注意：adminid字段保存另一用户的管理员用户id。一个用户可以是多个用户的管理员，或者一个用户可能有多个管理员。例如：

| id | name | email | phone | codeMeli |            | userid | adminid |
 ---- ------ ------- ------- ----------              -------- ---------
| 5  | mike | m@yaho| 12345 | 12345678 |            |   6    |    5    |
| 6  | sara | s@yaho| 54321 | 87654321 |            |   7    |    5    |
| 7  | joe  | j@yaho| 56421 | 65875234 |            |   7    |    8    |
| 8  | sag  | s@yaho| 57635 | 64616843 |

我使用OueryBuilder尝试了这个查询，效果很好：

Users::select('id','name','email','codeMeli','phone')
       ->join('user_admin','user_admin.userid','=','users.id')
       ->whereRaw("name LIKE '%".$name."%' and email LIKE '%".$email."%' and codeMeli LIKE '%".$codeMeli."%' and phone LIKE '%".$phone."%' and user_admin.adminid=".$CurrentUSerID)
       ->get();

但我想用雄辩的语言

这是我的用户型号：

<?php
namespace App;
use Illuminate\Database\Eloquent\Model;

class Users extends Model
{
    protected $table = 'users';
    public $timestamps = false;
    protected $fillable = ['name','phone','email','codeMeli','admin'];

    public function userAdmin()
    {
        return $this->belongsToMany('App\UserAdmin','id','userid');
    }
}

<?php
namespace App;
use Illuminate\Database\Eloquent\Model;

class UserAdmin extends Model
{
    protected $table = 'user_admin';
    public $timestamps = false;
    protected $fillable = ['userid','adminid'];

    public function users()
    {
       return $this->belongsToMany('App\Users','id','adminid');
    }
}

---

您可以将一个新的模型制作为与用户表相关的“管理”，并使用如下关系：

用户型号：

class Users extends Model
{
    protected $table = 'users';
    public $timestamps = false;
    protected $fillable = ['name','phone','email','codeMeli','admin'];


    public function userAdmin()
    {
        return $this->belongsToMany('App\Admin', 'user_admin', 'adminid', 'userid');
    }
}

class Admin extends Model
{
    protected $table = 'users';
    public $timestamps = false;
    protected $fillable = ['name','phone','email','codeMeli','admin'];
    public function userAdmin()
    {
        return $this->belongsToMany('App\Users', 'user_admin', 'userid', 'adminid');
    }
}

管理型号：

class Users extends Model
{
    protected $table = 'users';
    public $timestamps = false;
    protected $fillable = ['name','phone','email','codeMeli','admin'];


    public function userAdmin()
    {
        return $this->belongsToMany('App\Admin', 'user_admin', 'adminid', 'userid');
    }
}

class Admin extends Model
{
    protected $table = 'users';
    public $timestamps = false;
    protected $fillable = ['name','phone','email','codeMeli','admin'];
    public function userAdmin()
    {
        return $this->belongsToMany('App\Users', 'user_admin', 'userid', 'adminid');
    }
}

在您的控制器中：

$user = Users::find($CurrentUSerID)->userAdmin()->get();
