Laravel-无法获取管理员守卫的角色

Question

我有一个前端和管理区域。前端使用Laravel的Auth包，对于Admin我使用的是adminGuard，所有视图、控制器和模型都在admin目录下。

我正在尝试使用相同的角色和权限模型为前端和管理员用户设置角色和权限。为此，我创建了以下表格

• 管理员

问题是：我可以使用belongtomany（）为前端用户获取角色，但不能为管理员获取角色。这是代码。

namespace App;

use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;

class User extends Authenticatable
{
    use Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name',
        'email',
        'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password',
        'remember_token',
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];

    public function admin_roles()
    {
        return $this->belongsToMany('App\Admin\Role', 'role_admin');
    }

    public function roles() {
        return $this->belongsToMany('App\Admin\Role');
    }
}

namespace App\Admin;

use Illuminate\Database\Eloquent\Model;

class Role extends Model
{
    protected $fillable = ['name', 'display'];

    public function permissions()
    {
        return $this->belongsToMany('App\Admin\Permission');
    }

    public function admin_users()
    {
        return $this->belongsToMany('App\User');
    }

    public function users()
    {
        return $this->belongsToMany('App\User');
    }

}

{{auth()->user()->roles}}

// output 
[{"id":1,"name":"admin","display":"Admin","created_at":null,"updated_at":null,"pivot":{"user_id":1,"role_id":1}},{"id":2,"name":"supervisor","display":"Supervisor","created_at":null,"updated_at":null,"pivot":{"user_id":1,"role_id":2}}]

{{auth()->user()->admin_roles}}
//output
null - checked with dd()

Schema::create('role_admin', function (Blueprint $table) {
    $table->bigInteger('role_id')->unsigned();
    $table->bigInteger('admin_id')->unsigned();
    $table->foreign('role_id')->references('id')->on('roles')->onDelete('cascade');
    $table->foreign('admin_id')->references('id')->on('admins')->onDelete('cascade');
});

Schema::create('role_user', function (Blueprint $table) {
    $table->bigInteger('role_id')->unsigned();
    $table->bigInteger('user_id')->unsigned();
    $table->foreign('role_id')->references('id')->on('roles')->onDelete('cascade');
    $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
});

Schema::create('roles', function (Blueprint $table) {
    $table->bigIncrements('id');
    $table->string('name');
    $table->text('display');
    $table->timestamps();
});

Schema::create('permissions', function (Blueprint $table) {
    $table->bigIncrements('id');
    $table->string('model');
    $table->string('can');
    $table->timestamps();
});

Schema::create('permission_role', function (Blueprint $table) {
    $table->bigInteger('permission_id')->unsigned();
    $table->bigInteger('role_id')->unsigned();

    $table->foreign('permission_id')->references('id')->on('permissions')->onDelete('cascade');
    $table->foreign('role_id')->references('id')->on('roles')->onDelete('cascade');
});

Schema::create('admins', function (Blueprint $table) {
    $table->bigIncrements('id');
    $table->string('name');
    $table->string('email')->unique();
    $table->timestamp('email_verified_at')->nullable();
    $table->string('password');
    $table->rememberToken();
    $table->timestamps();
});

 <?php

namespace App\Admin;

use App\Notifications\Admin\ResetPasswordNotification;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;

class Admin extends Authenticatable
{
    use Notifiable;

    protected $guard = 'admin';

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name',
        'email',
        'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password',
        'remember_token',
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];

    public function sendPasswordResetNotification($token)
    {
        $this->notify(new ResetPasswordNotification($token));
    }
}

我已将角色管理的关系设置为管理模型，该模型之前被错误地放置在用户模型中。

<?php

namespace App\Admin;

use App\Notifications\Admin\ResetPasswordNotification;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;

class Admin extends Authenticatable
{
    use Notifiable;

    protected $guard = 'admin';

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name',
        'email',
        'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password',
        'remember_token',
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];

    public function sendPasswordResetNotification($token)
    {
        $this->notify(new ResetPasswordNotification($token));
    }

    public function roles()
    {
        return $this->belongsToMany('App\Admin\Role', 'role_admin');
    }
}

Answer 1

问题是您使用的是模型用户，而不是管理员

要恢复，请执行以下操作：

1. 从用户模型中删除管理员角色关系，并将其置于管理员模型中

Answer 2

看起来你的admin_roles关系在你的用户模型中，但是在你的迁移中，你已经声明了管理员表的外键。像这个

$table->foreign('admin_id')->references('id')->on('admins')->onDelete('cascade');

现在，假设您以管理员身份登录，那么您的管理员模型也应该具有这种关系。

public function admin_roles()
{
    return $this->belongsToMany('App\Admin\Role', 'role_admin', 'admin_id', 'role_id');
}
