django-filter实现区间过滤

# filters.py

from django_filters import FilterSet

class CourseFilterSet(FilterSet):
    
    # 课程的价格范围要大于等于min_price，小于等于max_price
    min_price = filters.NumberFilter(field_name='price', lookup_expr='gte')
    max_price = filters.NumberFilter(field_name='price', lookup_expr='lte')
    
    class Meta:
        model=models.Course
        fields=['course_category']
        
# views.py

class TestView(GenericViewSet, ListModelMixin):
     filter_backends=[DjangoFilterBackend]
	 # 配置类：（自己写的类）
     filter_class = CourseFilterSet
