如何使用 Laravel 一对一将用户数据传递到 JSON 文件

Question

我在使用一对一关系的 JSON 文件中获取用户数据时遇到问题这是我的 PostRequest 模型

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class PostRequest extends Model
{
    use HasFactory;

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

用户模型

<?php

namespace App\Models;

use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Laratrust\Traits\LaratrustUserTrait;
use App\Models\Verify;
use Illuminate\Support\Facades\Crypt;
use Illuminate\Database\Eloquent\Model;

class User extends Authenticatable
{
    use LaratrustUserTrait;
    use HasFactory, Notifiable;
    
    public function PostRequest(){
        return  $this->hasOne(PostRequest::class, 'artisan_id');
    }
}

控制器

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use Illuminate\Support\Facades\Auth;

use Illuminate\Support\Facades\DB;

use App\Models\PostRequest;
use App\Models\User;

class ChatController extends Controller
{
    public function getMessages(){

        return view('user/message'); //response()->json($contacts);
    }
    public function getContact(){
        $email = Auth::user()->email;
        
            $contacts = PostRequest::select('artisan_id')->where('email', '=', $email)
            ->limit('1')
            ->orderBy('id', 'DESC')
            ->user();
            return response()->json($contacts);
        //}

        
    }

}

如果运行上面的控制器我收到这个错误消息

[14:09:51] LOG.error: Call to undefined method Illuminate\Database\Eloquent\Builder:: user() {"userId":15,"exception":{}

如果我运行这个我得到所有数据，但是我需要一个特定的数据

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use Illuminate\Support\Facades\Auth;

use Illuminate\Support\Facades\DB;

use App\Models\PostRequest;
use App\Models\User;

class ChatController extends Controller
{
    public function getMessages(){

        return view('user/message'); //response()->json($contacts);
    }
    public function getContact(){
        $email = Auth::user()->email;
        
            $contacts = PostRequest::all();
            return response()->json($contacts);
        //}

        
    }

}

试试这个查询：

$email = Auth::user()->email;
$contacts = PostRequest::where('email', $email)->first()->user;
return response()->json($contacts);
