未定义属性: Illuminate\Database\Eloquent\Relations\HasOne::$user_id

Question

我只是拉拉威尔的初学者，如果这是个愚蠢的问题，对不起

，这是我的控制器:-

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\User;
use App\Profile;
use Auth;



class ProfilesController extends Controller
{

  public function _construct()
  {
    $this->middleware('auth');
  }

  public function create()
  {
    return view('bio');
  }

  public function store(Request $request)
  {
  auth()->user()->profile()->user_id;
    // create Bio
    $profile = new Profile;

    $profile->bio = $request->input('bio');
    $profile->save();
    return redirect('/home');

  }


}

，这是我的模型：-

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Profile extends Model
{
  protected $gaurded = [];
protected $fillable = ['user_id', 'bio'];

    public function user()
    {
      return $this->belongsTo(User::class);
    }
}

这是我的桌子

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Profile extends Model
{
  protected $gaurded = [];
protected $fillable = ['user_id', 'bio'];

    public function user()
    {
      return $this->belongsTo(User::class);
    }
}

这里是我的用户模型：-

  public function profile()
    {
      return $this->hasOne(Profile::class);
    }

    public function posts()
    {
      return $this->hasMany(Posts::class);
    }

我得到了这个错误“未定义的属性：，我不知道我哪里出错了，请帮助我，如果你能，感谢，请帮助我并指导我。

Answer 1

不能调用属性user_id on Illuminate\Database\Eloquent\Relations\HasOne profile()，

你可以用auth()->user()->profile->user_id来称呼它。

但是，用户还没有配置文件。如果需要在Illuminate\Database\Eloquent\Relations\HasOne上创建并使用Illuminate\Database\Eloquent\Relations\HasOne方法，Laravel将自动构建foreign_key user_id to profile。

  public function store(Request $request)
  {
      auth()->user()->profile()->create([
         'bio' => $request->input('bio')
      ]);
      return redirect('/home');
  }

Answer 2

在您的配置文件模型中

public function profile()
{
  return $this->hasOne(Profile::class,"user_id","id");
}

在你的控制器里

  public function store(Request $request)
  {
       echo $id = auth()->user->profile->user_id; 
       $input = $request->all();
       $input['user_id'] = auth()->id(); // OR auth()->user->profile->user_id;
       Profile::create($input);
       return redirect('/home');
  }

Answer 3

您需要在用户模型中定义外键和本地密钥，如下所示：

public function profile()
{
  return $this->hasOne(Profile::class,"user_id","id");
}
