问题描述
我要根据布尔字段“ is_featured”，创建日期和价格对产品进行排序。
我的目标： This is what i want to achieve. Images shows a website that I am taking ideas from.
我目前有一个复选框过滤器（通过django-filter实现），供用户根据品牌和类别进行过滤。您可以在https://ecommercelsm.herokuapp.com/product/
上看到我的“草稿”我想添加一个sort_by下拉菜单，如所附图像中的菜单，以便用户可以按过滤后的特征，价格或创建日期对产品的订单进行排序，或者不进行过滤。 我不知道该怎么做。有人可以帮忙吗？我觉得我需要在我的ProductFilter中添加更多字段。
