一对多和一对多关系laravel

Question

这是项目迁移

    Schema::create('projects', function (Blueprint $table) {
        $table->increments('id');
        $table->string('name');
        $table->string('start_date');
        $table->string('end_date');
        $table->string('con');
        $table->timestamps();
    });

这是时间表

    Schema::create('timesheets', function (Blueprint $table) {
        $table->increments('id');
        $table->string('user_id');
        $table->string('project_id');
        $table->string('day');
        $table->string('month');
        $table->string('year');
        $table->string('jalali');
        $table->string('timesheet_h');
        $table->string('timesheet_m');
        $table->timestamps();
    });

这样用户就可以迁移了

    Schema::create('users', function (Blueprint $table) {
        $table->increments('id');
        $table->string('name');
        $table->string('mobile');
        $table->string('salary_base');
        $table->string('salary_base_h');
        $table->string('start_contract');
        $table->string('end_contract');
        $table->string('start_insurance');
        $table->string('end_insurance')->nullable();
        $table->string('first_salary');
        $table->string('date_birth');
        $table->string('melli_code');
        $table->string('s_number');
        $table->string('nda');
        $table->string('work_rules');
        $table->string('end_work')->nullable();
        $table->string('password');
        $table->rememberToken();
        $table->timestamps();
    });

这是我的项目模型

public function timesheets()
{
    return $this->hasMany(timesheet::class,'project_id');
}

这是我的时间表模型：

public function projects()
{
    return $this->belongsTo(project::class,'project_id');
}

public function users()
{
    return $this->belongsTo(User::class,'user_id','id');
}

这是我的用户模型

public function project_peoples()
{
    return $this->hasMany('App\project_people');
}
public function timesheets()
{
    return $this->belongsTo(timesheet::class);
}

public function projects()
{
    return $this->belongsTo(project::class);
}

现在，我从项目返回我的查询

public function allProject()
{
    $projects=project::with(['timesheets','users'])->get();

    return $projects;
  }

这是可以的，但user_id用户在timesheets.user_id我不能得到它的时间表，并得到它

此控制器按时间表中的项目id返回项目和时间表，但时间表中的用户id我不知道如何将其输入系统

这是我的回报，我有2个用户，但重复我的2个用户：（

Answer 2

使用点语法加载嵌套关系：

project::with('timesheets.users')->get();
