雄性幼虫急切加载的条件

Question

I get my Product be this code. I use with() method to load variations relation. I have some filters for it. But if any variations does't exist I get Product.

How can I get only this Product where variations exist ?

$query = Product::with(array(
            'variations' => function($query) use($filters){
                if(isset($filters['price_start']) && !empty($filters['price_start'])){
                    $query->groupBy('id')->having(DB::raw('SUM(price_base + price_engraving)'), '>=', $filters['price_start']);
                }
                if(isset($filters['price_end']) && !empty($filters['price_end'])){
                    $query->groupBy('id')->having(DB::raw('SUM(price_base + price_engraving)'), '<=', $filters['price_end']);
                }

                if(isset($filters['q_magazine_start']) && !empty($filters['q_magazine_start'])){
                    $query->where('q_magazine', '>', $filters['q_magazine_start']);
                }
                if(isset($filters['q_magazine_end']) && !empty($filters['q_magazine_end'])){
                    $query->where('q_magazine', '<', $filters['q_magazine_end']);
                }

                return $query;
            }
        ))->whereIn('id', $productList);

To accomplish that you have to do pretty much the same thing again but with whereHas . Since the closure will be exactly the same we can put it in a variable to avoid duplicate code:

$filterClosure = function($query) use ($filters){
    if(isset($filters['price_start']) && !empty($filters['price_start'])){
        $query->groupBy('id')->having(DB::raw('SUM(price_base + price_engraving)'), '>=', $filters['price_start']);
    }
    if(isset($filters['price_end']) && !empty($filters['price_end'])){
        $query->groupBy('id')->having(DB::raw('SUM(price_base + price_engraving)'), '<=', $filters['price_end']);
    }

    if(isset($filters['q_magazine_start']) && !empty($filters['q_magazine_start'])){
        $query->where('q_magazine', '>', $filters['q_magazine_start']);
    }
    if(isset($filters['q_magazine_end']) && !empty($filters['q_magazine_end'])){
        $query->where('q_magazine', '<', $filters['q_magazine_end']);
    }
};

$query = Product::with(array('variations' => $filterClosure))
                ->whereHas('variations', $filterClosure)
                ->whereIn('id', $productList);

(By the way, there's no need to return $query at the end of the anonymous function)

Edit

As we figured out you need to change the groupBy statements to where

$filterClosure = function($query) use ($filters){
    if(isset($filters['price_start']) && !empty($filters['price_start'])){
        $query->where(DB::raw('price_base + price_engraving'), '>=', $filters['price_start']);
    }
    if(isset($filters['price_end']) && !empty($filters['price_end'])){
        $query->where(DB::raw('price_base + price_engraving'), '<=', $filters['price_end']);
    }

    // same code as above
};
