laravel eloquent 根据 auth 用户和项目 id 获取相关任务

Question

嗨，我很困惑我应该如何编写雄辩的查询要获取项目所属的相关客户，这是在projects 和tasks 表client_id 理想情况下我想访问此页面app.dev/project/3/tasks 这样很简单，可以路由到：

Route::any("project/{resource}/tasks", [
        "as"   => "project/projectrelatedtasks",
        "uses" => "ProjectController@projectrelatedtasks"
    ]);

我不确定编写此查询的最简单方法是什么，我可以轻松地在下面批量获取所需的内容，就像在我的存储库中一样：

public function getProjectTasks() {
//This fetches the auth users projects, the client to who it belongs and its related tasks
//not sure how to insert another find with $id 
    return \User::with(array('projects', 'projects.clients', 
    'projects.tasks'))->find(Auth::user()->id);
}

这在我的控制器中：

public function projectrelatedtasks() {
            $projects = $this->project->getProjectTasks();
            return $projects;
        }

但我想通过它的 id 将其限制为一个项目，不确定执行此查询的最佳和最有效的方法是什么，有人可以帮我解决这个问题吗？谢谢

编辑

存储库：

public function getProjectTasks($id) {

    return \Projects::with(['clients', 'tasks'])
        ->whereUserId(Auth::user()->id)
        ->find($project_id);
}

路线：

Route::any("project/{resource}/tasks", [
        "as"   => "project/projectrelatedtasks",
        "uses" => "ProjectController@projectrelatedtasks"
    ]);

控制器：

public function projectrelatedtasks($id)
    {

    // get the Project tasks
        $project = $this->project->getProjectTasks($id);
        return $project;        
    }

Answer 1

您可以使用闭包将参数传递给with 内的表：

// Assume $project_id is defined as the id of the project of interest
$user = User::with([
    'projects' => function($query) use ($project_id)
    {
        return $query->whereId($project_id);
    },
    'projects.clients',
    'projects.tasks'
])->find(Auth::user()->id);

但您应该从Project 本身开始，因为表projects 有一个列user_id：

// Again, assuming $project_id is defined
Projects::with(['clients', 'tasks'])
        ->whereUserId(Auth::user()->id)
        ->find($project_id);
