優化，以獲得所需的Laravel查詢數據

Question

我有我的Laravel項目中的以下車型

1. 商人
2. 優惠
3. 新政投票
4. 新政點擊次數
5. 交易交易類型
6. 商人評分

這是我的招商模式看起來像

class Merchants extends Model 
{ 
    // 
    public function deals() 
    { 
     return $this->hasMany('App\Deals', 'merchant_id', 'merchant_id'); 
    } 
} 

優惠型號

class Deals extends Model 
{ 
// 
    public function clicks() 
    { 
     return $this->hasMany('App\Clicks', 'deal_id', 'deal_id'); 
    } 
    public function merchants() 
    { 
     return $this->hasOne('App\Merchants', 'deal_id', 'deal_id'); 
    } 
    public function votes() 
    { 
     return $this->hasMany('App\Deal_votes', 'deal_id', 'deal_id'); 
    } 
    public function deal_dealtypes() 
    { 
     return $this->hasMany('App\Deal_dealtypes', 'deal_id', 'deal_id'); 
    } 
} 

商家評級模型的

public function merchants() 
    { 
     return $this->belongsTo('App\Merchants', 'merchant_id', 'merchant_id'); 
    } 

對於特定商家着陸頁，我試圖得到一些商家信息，與商家相關的交易，每筆交易的投票和點擊次數。這是我迄今

$merchant = Merchants::where('merchant_url_text', $merchant_url_text) 
       -> with('categories' ,'deals','deals.votes','deals.clicks', 'deals.deal_dealtypes') 
       -> first(); 

然而，這是返回商戶信息，交易信息，所有的選票記錄綁在新政和所有的點擊綁每筆交易完成。

附樣本數據的反應，我需要一些幫助，下面

1. 獲取有限的領域，不是所有領域依賴於商家
2. 從交易對象
獲取有限的字段
3. 在響應

Answer 1

表決，且每筆交易次數的獲取計數爲了讓有限的領域，你可以使用select()功能，並獲得數可以使用withCount()功能。

所以您的查詢就會爲：

$merchant = Merchants::where('merchant_url_text', $merchant_url_text) 
        ->select('id', 'name') 
        ->with(['deals' => function($q) { 
          $q->select('id', 'name') 
           ->with('votes','clicks', 'deal_dealtypes') 
           ->withCount('votes') 
           ->withCount('clicks'); 
         }]) 
        ->with('categories') 
        -> first();
