检索角色名称以收集laravel中的用户 [英] Retrive Roles name for collection of users in laravel

问题描述

我想将用户角色传递给blade.

i want to pass users role to blade .

Usercontroller:

Usercontroller :

    public function index(){

    $users  = User::with('roles')->paginate(10);
    foreach ($users as $user ) {
       echo ( !$user->roles->isEmpty() ? $user->roles->name : 'No Role' );
    }
}

Create_role_table_migration:

Create_role_table_migration:

        Schema::create('roles', function (Blueprint $table) {
        $table->increments('id')->unique();
        $table->string('name', 45);
        $table->string('lable', 45);
        $table->timestamps() ;
    });

我得到的错误:

UsersController.php第23行中的

ErrorException:未定义的属性:Illuminate \ Database \ Eloquent \ Collection :: $ name

ErrorException in UsersController.php line 23: Undefined property: Illuminate\Database\Eloquent\Collection::$name

我试图获取的名称"有什么问题?

whats wrong with the "name" i trying to get ?

ps:当我更改时:

           echo ( !$user->roles->isEmpty() ? $user->roles->name : 'No Role' ); 

至:

           echo ( !$user->roles->isEmpty() ? $user->roles : 'No Role' );

此结果将显示:

但是我只是尝试从上面的行中获取名称"

but i just try to fetch 'name' from above rows

推荐答案

我自己找到解决方案:

我必须使用:

 user->roles->first()->name

而不是:

user->roles->->name

由于用户->角色"返回一个集合，因此在尝试获取对象属性之前，我必须使用集合方法

cause "user->roles" return a collection and i must use collection method before trying to get object properties
