如何收集Laravel雄辯查詢中的項目？

Question

我正在嘗試爲用戶提取所有配置文件數據。並且用戶可以爲服務器上傳多個可以給用戶徽章的文件。我的測試環境中有2個用戶，其中1個用戶有3個文件。現在，當我從控制器返回JSON時，我得到了三個結果，但我想要合併或以某種方式組合，因此一個用戶可以將所有數據放在一個對象中。

這是我目前得到恢復

[ 
    { 
     "id":1, 
     "avatar":"john.jpg", 
     "role":2, 
     "first_name":"John", 
     "last_name":"Doe", 
     "user_name":"johndoe", 
     "account_status":2, 
     "one_child":"6", 
     "introduction":"test", 
     "file_type":1, 
     "file":"1498725633.docx", 
     "status":2, 
     "lat":59.44, 
     "lng":24.74, 
     "rating":"5", 
     "recommended":"1", 
     "rating_count":2, 
     "distance":0.29988841983648 
    }, 
    { 
     "id":1, 
     "avatar":"john.jpg", 
     "role":2, 
     "first_name":"Joe", 
     "last_name":"Doe", 
     "user_name":"johndoe", 
     "account_status":2, 
     "one_child":"6", 
     "introduction":"test", 
     "file_type":4, 
     "file":"118771941-merged.mp4", 
     "status":1, 
     "lat":59.44, 
     "lng":24.74, 
     "rating":"5", 
     "recommended":"1", 
     "rating_count":2, 
     "distance":0.29988841983648 
    }, 
    { 
     "id":4, 
     "avatar":"capture.JPG", 
     "role":2, 
     "first_name":"Jane", 
     "last_name":"Doe", 
     "user_name":"janedoe", 
     "account_status":2, 
     "one_child":"4", 
     "introduction":"Test", 
     "file_type":2, 
     "file":"1498732136.docx", 
     "status":1, 
     "lat":59.46, 
     "lng":24.83, 
     "rating":"3", 
     "recommended":"2", 
     "rating_count":2, 
     "distance":5.5651349391591 
    } 
] 

正如你可以看到李四有兩個文件，但我想有一個對象下的所有文件和文件類型，因此將只有一個約翰JSON和一個Jane對象atm。

這裏是我的原始SQL從laravel

提取我所有的連接，我在遷移做出users table所以user_id引用id。我怎樣才能獲取一個用戶對象下的所有文件？

Answer 1

而不是在查詢中加入users和user_files表，您可以爲它們添加relation。

你的情況給users模式將有一個功能是這樣的：

public function files() 
{ 
    return $this->hasMany('App\UserFiles', 'user_id'); 
    //Where UserFiles is the name of the model of the user_files table 
    //and user_id is the foreign key 
} 

一旦這種關係建立了，你可以通過使用with添加files關係到你的查詢：

Users::with('files')->where(...)->orderBy(...)->get(); 

這將文件加載到用戶對象，像這樣：

{ 
    "id":1, 
    "avatar":"john.jpg", 
    "role":2, 
    "first_name":"John", 
    "last_name":"Doe", 
    "user_name":"johndoe", 
    "account_status":2, 
    "one_child":"6", 
    "introduction":"test", 
    "files": [ 
     { 
      //File Object 
     }, 
     { 
      //File Object 
     } 
    ], 
    "lat":59.44, 
    "lng":24.74, 
    "rating":"5", 
    "recommended":"1", 
    "rating_count":2, 
    "distance":0.29988841983648 
}
