Django-filter報錯：__init__() got an unexpected keyword argument 'name'

原因是 自從 django-filter2.0之后 將Filter的name字段 更名為 field_name 所以需要這樣寫：

class GoodsFilter(filters.FilterSet):
pricemin = filters.NumberFilter(field_name="shop_price", lookup_expr='gte')
pricemax = filters.NumberFilter(field_name="shop_price", lookup_expr='lte')

class Meta:
model = Goods
fields = ['pricemin', 'pricemax']
