django filters TypeError __init__() got an unexpected keyword argument 'lookup_type'

按照DRF文档 配置django_filters 筛选

import django_filters
from myapp.models import Product
from myapp.serializers import ProductSerializer
from rest_framework import generics

class ProductFilter(django_filters.FilterSet):
    min_price = django_filters.NumberFilter(name="price", lookup_type='gte')
    max_price = django_filters.NumberFilter(name="price", lookup_type='lte')
    class Meta:
        model = Product
        fields = ['category', 'in_stock', 'min_price', 'max_price']

class ProductList(generics.ListAPIView):
    queryset = Product.objects.all()
    serializer_class = ProductSerializer
    filter_class = ProductFilter

在请求此接口时发生错误

TypeError at /api/project-center/
__init__() got an unexpected keyword argument 'lookup_type'

在看了django_filters 官方文档示例后将lookup_type 更换为lookup_expr后正常。

class ProductFilter(django_filters.FilterSet):
    price = django_filters.NumberFilter()
    price__gt = django_filters.NumberFilter(name='price', lookup_expr='gt')
    price__lt = django_filters.NumberFilter(name='price', lookup_expr='lt')

    release_year = django_filters.NumberFilter(name='release_date', lookup_expr='year')
    release_year__gt = django_filters.NumberFilter(name='release_date', lookup_expr='year__gt')
    release_year__lt = django_filters.NumberFilter(name='release_date', lookup_expr='year__lt')

    manufacturer__name = django_filters.CharFilter(lookup_expr='icontains')

    class Meta:
        model = Product
