Question

我想显示与user表链接的profile表中的数据。我在vardump中获取数据，但我不知道如何一对一地显示它。这是我的功能：

public function show($id)
{
    //Get data from user
    $user = User::find($id);
    //Get the horse count connect to the user
    $horse_count = DB::table('horses')->where('user_id', $id)->count();

    var_dump($user->profile);
    die();
}

它返回：

object(Illuminate\Database\Eloquent\Collection)#188 (1) {
  ["items":protected]=>
  array(1) {
    [0]=>
    object(App\Profile)#189 (24) {

  }
}

但是当我echo $user->profile->age;时它什么都没有显示出来。有关信息，我将表user和profile与return $this->belongsTo('App\User');和return $this->hasMany('App\Profile');相互关联。我得到的数据，但我不能一个一个地显示它。

每人一个：

foreach (User::find($id)->profile as $profile) {
     // Do what you want, e.g.
     echo $profile->age;
}

请记住，如果用户有很多个人资料，那么关系函数名称应该是复数，如public function profiles()

Laravel不显示数据
