django_filters实现搜索

定义model

# models.py

class Product(models.Model):

    name = models.CharField(max_length=255)
    author = models.CharField(max_length=255)

    price = models.DecimalField()

    description = models.TextField()

定义filter

# filters.py

import django_filters

class ProductFilter(django_filters.FilterSet):

    name = django_filters.CharFilter(lookup_expr='iexact')  # iexact表示精确匹配, 并且忽略大小写

    author = django_filters.CharFilter(lookup_expr='icontains') #icontains表示模糊查询（包含），并且忽略大小写

    price = django_filters.NumberFilter(look_expr='exact')  #exact表示精确匹配

    desc = django_filters.CharFilter('description', lookup_expr='contains') #对'description'字段进行操作，不填默认为desc

    #price__lte = django_filters.NumberFilter('price', lookup_expr='lte') #lte表示小于

    #price__gte = django_filters.NumberFilter('price', look_expr='gte')  # gte表示大于

class Meta:

        model = Product

        fields = ['name', 'author', 'price', 'description']

        #fields = {

　            'price': ['lt', 'gt']

        }

views中使用

class ProductViewSets(mixins.ListModelMixin,

                   mixins.RetrieveModelMixin,

                   mixins.UpdateModelMixin,

                   mixins.DestroyModelMixin,

                   mixins.CreateModelMixin,

                   viewsets.GenericViewSet):

    queryset = Product.objects.all()

    serializer_class = ProductSerializer 
    filter_backends = (DjangoFilterBackend,)

    filter_class = ProductFilter

    search_fields = ('name', 'description')  # 模糊搜索的字段

    ordering_fields = ('price',)  # 排序的字段
