问题描述
我想过滤多个包含多个查询的字段：
I want to filter multiple fields with multiple queries like this:
api/listings/?subburb=Subburb1, Subburb2&property_type=House,Apartment,Townhouse,Farm .. etc
有没有内置的方式，我看在django过滤器，但它似乎有限，我想我必须手动在我的api视图，但它变得凌乱，过滤器上过滤器过滤器
Are there any built in ways, I looked at django-filters but it seems limited, and I think I would have to do this manually in my api view, but its getting messy, filtering on filters on filters
推荐答案
过滤器上的过滤器过滤器不是乱码，它被称为链接过滤器。
filtering on filters on filters is not messy it is called chained filters.
连锁过滤器是必要的，因为有时候会有 property_type 有些时候没有：
And chain filters are necessary because sometime there is going to be property_type some time not:
if property_type:
qs = qs.filter(property_type=property_type)
如果你以为会有多个查询，那么它仍然会在一个查询中执行，因为queryset是懒惰的。
If you are thinking there is going to be multiple queries then not, it will still executed in one query because queryset are lazy.
或者你可以建立一个dict并传递一次：
Alternatively you can build a dict and pass it just one time:
d = {'property_type:': property_type, 'subburb': subburb}
qs = MyModel.objects.filter(**d)
