我的Laravel项目中有以下模型
这就是我的商家模型的样子
class Merchants extends Model
{
//
public function deals()
{
return $this->hasMany('App\Deals', 'merchant_id', 'merchant_id');
}
}
交易模型
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');
}
}
商家评级模型
public function merchants()
{
return $this->belongsTo('App\Merchants', 'merchant_id', 'merchant_id');
}
对于特定的商家登陆页面，我正在尝试获取一些商家信息，与商家相关的交易，每笔交易的点票数和点击次数。这就是我到目前为止所做的事情
$merchant = Merchants::where('merchant_url_text', $merchant_url_text)
-> with('categories' ,'deals','deals.votes','deals.clicks', 'deals.deal_dealtypes')
-> first();
然而，这将返回商家信息，交易信息，与交易相关的所有投票记录以及与每笔交易相关的所有点击。

要获得有限的字段，您可以使用select()函数并获取可以使用withCount()函数的计数。
所以你的查询将是：
$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();
