Question

我有关联广告表，用户如何向用户展示数据。它显示我试图获取非对象属性的错误关联。

表：

广告
用户（默认Laravel）

在用户模型中：

    public function ads()
    {
        return $this->hasMany('App\Ad','user_id');
    }
    In Ad Model
    public function user()
    {
        return $this->belongsTo('App\User');
    }

    in Routes
Route::get('/ads',function(){
      $ads = Ad::get();
      //print_r($ads);
   foreach ($ads as $ad) {
          echo $ad->user->name;// issue here

   }
});

我在print_r($ad->user);

App \ User Object（[fillable：protected] =＆gt; Array（[0] =＆gt; name [1] =＆gt; phone [2] =＆gt; email [3] =＆gt; password [4] = ＆gt;角色）[隐藏：受保护] =＆gt;数组（[0] =＆gt;密码[1] =＆gt; remember_token）[connection：protected] =＆gt; [table：protected] =＆gt; [primaryKey：protected] =＆gt; id [perPage：protected] =＆gt; 15 [递增] =＆gt; 1 [时间戳] =＆gt; 1 [属性：受保护] =＆gt;数组（[id] =＆gt; 1 [名称] =＆gt;伊尔凡[电子邮件] =＆GT; irfan0786@gmail.com [电话] =＆GT; 43434 [口令] =＆GT; $ 2Y $ 10 $ dnUuC9yxQwSHcpWy1oZlpuxaU33eBz1VYCPFQgfJYtncDivmDfqym [作用] =＆gt;用户[remember_token] =＆GT; x3l3x1tkXUB3I7KiRggPRclnCR5JGnDLlzCxZxeAmfpGCYFR0ylSrKNwSSuy [created_at] =＆GT; 2016-06-12 17:42:36 [updated_at] =＆gt; 2016-06-22 03:26:28）[original：protected] =＆gt;数组（[id] =＆gt; 1 [name] =＆gt; irfan [email] =＆gt; irfan0786@gmail.com [phone] =＆gt; 43434 [密码] =＆gt; $ 2y $ 10 $ dnUuC9yxQwSHcpWy1oZlpuxaU33eBz1VYCPFQgfJYtncDivmDfqym [role] =＆gt;用户[remember_token] =＆gt; x 3l3x1tkXUB3I7KiRggPRclnCR5JGnDLlzCxZxeAmfpGCYFR0ylSrKNwSSuy [created_at] =＆gt; 2016-06-12 17:42:36 [updated_at] =＆gt; 2016-06-22 03:26:28）[关系：受保护] =＆gt; Array（）[visible：protected] =＆gt; Array（）[appends：protected] =＆gt; Array（）[guarded：protected] =＆gt;数组（[0] =＆gt; *）[日期：受保护] =＆gt; Array（）[dateFormat：protected] =＆gt; [casts：protected] =＆gt; Array（）[touches：protected] =＆gt; Array（）[observables：protected] =＆gt; Array（）[with：protected] =＆gt; Array（）[morphClass：protected] =＆gt; [exists] =＆gt; 1 [wasRecentlyCreated] =＆gt; ）

Answer 1

要获取您应使用的所有广告，Ad::all()不是Ad::get()。

更新您的Ad模型，因为一个用户只有一个广告：

public function ads()
{
    return $this->hasOne('App\Ad','user_id');
}
