按照DRF文檔 配置django_filters 篩選
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
在請求此接口時發生錯誤
TypeError at /api/project-center/
__init__() got an unexpected keyword argument 'lookup_type'
在看了django_filters 官方文檔示例后將lookup_type 更換為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
