Laravel 复杂查询更改 Eloquent 为 Query Builder

Question

我有一个雄辩的查询：

$model->select(
        'product_templates.id',
        'product_templates.name',
        'product_templates.short_name',
        'product_templates.code',
    )
    ->withWhereHas('products', function ($query)  {
        $query->select(
            'products.id',
            'products.product_template_id',
            'products.category_id',
            'products.sub_category_id',
            'products.company_id',
            'products.product_size_id',
            'products.expire_date',
        )
            ->when(request('sub_category_id'), function ($query)  {
                $query->where('sub_category_id', request('sub_category_id'));
            })
            ->where('company_id', request('company_id'))
            ->where('category_id', request('category'))
            ->with('productSize:id,name')
            ->withSum('stocks', 'quantity')
            ->withSum('orderItems', 'quantity');
    })
    ->orderBy('name')
    ->get();

输出：

        }
    }]
},

现在如何在不改变输出结果的情况下通过 QueryBuilder 实现这个查询？

我这样试：

return Product::query()
    ->select(
        'products.*',
    )
    ->where('products.category_id', request()->category)
    ->when($subCategoryId = request('sub_category_id'), function ($query) use ($subCategoryId) {
        $query->where('products.sub_category_id',  $subCategoryId);
    })
    ->when($companyId = request('company_id'), function ($query) use ($companyId) {
        $query->where('products.company_id',  $companyId);
    })

    ->join('sub_categories',  'sub_categories.id',  '=', 'products.sub_category_id')
    ->join('product_sizes',  'product_sizes.id',  '=', 'products.product_size_id')
    ->join('product_templates', function($join){
        $join->on('product_templates.id',  '=', 'products.product_template_id');
        $join->on('product_template_images.product_template_id',  '=', 'product_templates.id');
    })
    ->orderBy('product_templates.name')
    ->get();

但是输出结果是plain collections。
