Laravel雄辯 - >負載（）沒有返回預期的結果

Question

我有關係，那就是建立這樣的，

Organisation.php

public function projects() 
    { 
     return $this->belongsToMany('Project'); 
    } 

Project.php

public function organisations() 
    { 
     return $this->belongsToMany('Organisation'); 
    } 

我運行以下查詢，

$project = Project::where('user_id', '=', ResourceServer::getOwnerId()) 
        ->whereNull('organisation_id') 
        ->get(array(
         'projects.id', 
         'projects.name', 
         'projects.description', 
         'projects.total_cost', 
         'projects.sales_person', 
         'projects.project_manager', 
         'projects.client_id', 
         'projects.start_date', 
         'projects.finish_date', 
         'projects.organisation_id', 
         'projects.created_at', 
         'projects.user_id', 
         'projects.owner_id', 
         'projects.status' 
        )); 

     $project->load('salesperson'); 
     $project->load('projectmanager'); 
     $project->load('clients')->load('clients.users'); 
     $project->load('organisations')->load('organisations.users'); 
     $project->load('collaborators'); 
     $project->load('user'); 

     $owned_by_me = $project->toArray(); 

個我回來的結果是這樣的，

正如你所看到的組織屬性是空的，但就是憑藉具有organisation_id它應該返回的組織。

爲什麼不這樣做？

Answer 1

這是belongsTo：

public function organisation() 
{ 
    return $this->belongsTo('Organisation'); 
} 

belongsToMany是透視表，這是不是這裏的情況，因爲你有一個organisation_id的M-M的關係，對不對？像上面那樣改變它，你很好走。

在這種情況下，也關係的另一側應改爲hasMany（儘管它不是你粘貼代碼中的一個問題）：

public function projects() 
{ 
    return $this->hasMany('Project'); 
}
