Laravel hasone关系 [英] Laravel hasone relationship

问题描述

我正在尝试使用hasone关系，但得到空错误.下面是我的代码

I am trying to use hasone relation but getting null error. below is my code

用户模型:

  function profile()
{
    $this->hasOne('App\Profile');
}

个人资料模型:

   function User()
{
    return $this->belongsTo('App\User');
}

注册控制器

 protected function create(array $data)
{
    $user =  User::create([
        'name' => $data['name'],
        'email' => $data['email'],
        'password' => Hash::make($data['password']),
    ]);

    if($user) {

        $profile = new Profile();
        $profile->name = 'Fake Name';
        $profile->father = 'Fake Father';
        $user->profile()->save($profile);
    }

    return $user;

}

错误:在null上调用成员函数save()

Error: Call to a member function save() on null

推荐答案

将User.php更改为

Change User.php to

  function profile()
  {
    return $this->hasOne('App\Profile');
  }

您需要返回关系实例.
