Django filters

import django_filters

from .models import Goods

class GoodsFilter(django_filters.rest_framework.FilterSet):
    """
    商品过滤类
    """
    price_min = django_filters.NumberFilter(name='shop_price', lookup_expr='gte')
    price_max = django_filters.NumberFilter(name='shop_price', lookup_expr='lte')
    name = django_filters.CharFilter(name='name', lookup_expr='icontains')

    class Meta:
        model = Goods
        fields = ['price_min', 'price_max', 'name']

实现对字段的过滤，lookup_expr有（exact, not_exact, lt, gt, gte, lte, startswith, endswith, contains, icontains, not_contains）等匹配功能

当然也可以定义函数进行对特定字段进行过滤

定义好了Filter类后，在View里面加上下面这句话

 filter_class = GoodsFilter

Rest Framework filters

from rest_framework import viewsets, filters
from rest_framework.pagination import PageNumberPagination
from django_filters.rest_framework import DjangoFilterBackend
from .serializer import GoodsSerializer
from .filters import GoodsFilter

from .models import Goods

class GoodsPagination(PageNumberPagination):
    page_size = 10
    page_query_param = 'p'
    page_size_query_param = 'page_size'
    max_page_size = 100


class GoodsListViewSet(viewsets.ModelViewSet):
    """
    This viewset automatically provides
    `list`, `create`, `retrieve`,
    `update` and `destroy`
    actions.
    """
    queryset = Goods.objects.all()
    serializer_class = GoodsSerializer
    pagination_class = GoodsPagination
    filter_backends = (DjangoFilterBackend, filters.SearchFilter, filters.OrderingFilter)
    filter_class = GoodsFilter
    search_fields = ('name', 'goods_desc', 'goods_brief')
    ordering_fields = ('shop_price',)

可以实现搜索（有精确搜索，模糊搜索，包含可以搜索到的字段等功能），排序等功能进行过滤
