如何从两个以上的表laravel中获得价值？

如何解决如何从两个以上的表laravel中获得价值？

我的雄辩幼虫有问题。我无法从表中获取数据。 这是必要条件：从表test_1，test_2和test_3获取列表用户和总和值。 这是我的桌子： 用户表：

Schema::create('users',function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('name');
            $table->string('username');
            $table->string('email')->unique();
            $table->timestamp('email_verified_at')->nullable();
            $table->string('password');
            $table->rememberToken();
            $table->timestamps();

        });

test_1表：

Schema::create('tests_1',function (Blueprint $table) {
            $table->increments('id');
            $table->unsignedBigInteger('user_id');
            $table->smallInteger('test_a')->nullable();
            $table->smallInteger('test_b')->nullable();
            $table->timestamps();

            $table->foreign('user_id')
                ->references('id')
                ->on('users');
        });

test_2表：

Schema::create('tests_2',function (Blueprint $table) {
            $table->id();
            $table->unsignedBigInteger('user_id');
            $table->smallInteger('test_a')->nullable();
            $table->smallInteger('test_b')->nullable();
            $table->timestamps();

            $table->foreign('user_id')
                ->references('id')
                ->on('users');
        });

test_3表：

Schema::create('tests_3',function (Blueprint $table) {
            $table->id();
            $table->unsignedBigInteger('user_id');
            $table->smallInteger('test_a')->nullable();
            $table->smallInteger('test_b')->nullable();
            $table->timestamps();

            $table->foreign('user_id')
                ->references('id')
                ->on('users');
        });

我的控制器：

$users = User::with(['test1' => function($query){
                        $query->select('*',DB::raw("SUM(test_a + test_b) as score1"));
                    }])
                    ->with(['test2' => function($query){
                        $query->select('*',DB::raw("SUM(test_a + test_b) as score2"));
                    }])
                    ->with(['test3' => function($query){
                        $query->select('*',DB::raw("SUM(test_a + test_b) as score3"));
                    }])
                    ->get();


        return view('home',compact('users'));

我的观点：

<table>
                        <tr>
                            <th>Name</th>
                            <th>Total Score 1</th>
                            <th>Total Score 2</th>
                            <th>Total Score 3</th>
                        </tr>
                        @foreach($users as $key=> $user)
                        <tr>
                            <td>{{ $user->username }}</td>
                            <td>{{ $user->test->score1 }}</td>
                            <td>{{ $user->test->score2 }}</td>
                            <td>{{ $user->test->score3 }}</td>
                        </tr>
                        @endforeach
                    </table>

我遇到错误并停留在那儿。

我的模特： 用户模型：

class User extends Authenticatable
{
    use Notifiable;

    protected $fillable = [
        'name','username','email','password',];

    protected $hidden = [
        'password','remember_token',];

    protected $casts = [
        'email_verified_at' => 'datetime',];

    public function test1()
    {
        return $this->hasOne('App\Test1');
    }

    public function test2()
    {
        return $this->hasOne('App\Test2');
    }

    public function test3()
    {
        return $this->hasOne('App\Test3');
    }
}

Test1模型：

class Test1 extends Model
{
    protected $table = 'tests_1';
    
    protected $fillable = [
        'user_id','test_a','test_b',];

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

Test2模型：

class Test2 extends Model
{
    protected $table = 'tests_2';
    
    protected $fillable = [
        'user_id',];

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

Test3模型：

class Test3 extends Model
{
    protected $table = 'tests_3';
    
    protected $fillable = [
        'user_id',];

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