Django过滤器按相关字段过滤

我有两张桌子.

class Writer(models.Model)
    name = model.CharField()
    ...

class Article(models.Model)
    name = model.CharField()
    writer = model.ForeignKey('Writer',related_name="relationship") 
    ...

我想构建一些获取编写器列表的API端点,但这应该可以通过Article id过滤.
我正在使用django-filter.所以：

class WriterViewSet(viewsets.ReadOnlyModelViewSet):
   filter_backend = [filters.djangoFilterBackend],filter_class = WriterFilter


class WriteFilter(django_filters.rest_framework.FilterSet):
....

所以我关心的是,如何通过文章定义WriteFilter来过滤Writer？

解决方法

class WriteFilter(django_filters.rest_framework.FilterSet):
    article = django_filters.CharFilter(name='relationship__name',lookup_expr='contains')

    class Meta:
        model = WriterFilter
        fields = ['article']

你的网址会是这样的,/ API / wtiter /列表/？文章= somearticlename
