django-drf框架中排序和查询组件

一查询相关

1.模糊查询

1.导入模块组件

from rest_framework.filters import SearchFilter

2.自定义视图类中的相关设置参数

from rest_framework.viewsets import ModelViewSet
from rest_framework.filters import SearchFilter
class CarModelViewSet(ModelViewSet):
    queryset = .....
    serializer_class = .....
    search_fields = ['字段一名称','字段二名称'] #能够用()包裹,写前面的优先级大于后面
    filter_backends = [SearchFilter,]

其中search_fields前面添加各类字符来限制搜索行为

• ^以指定内容开头
• =彻底匹配
• @全文搜索(目前只支持django数据存放在mysql)
• $正则匹配

2.自定义查询

1.自定义条件导入模块及设置

from django_filters.rest_framework import FilterSet
from django_filters import filters
from . import models
class CarFilterSet(FilterSet):
    min_price = filters.NumberFilter(field_name='类里面的字段名称', lookup_expr='gte') #gte为大于等于
    max_price = filters.NumberFilter(field_name='类里面的字段名称', lookup_expr='lte')#lte为小于等于
    class Meta:
        model = 字段所在的类名
        # brand仍是实现分类
        # min_price，max_price能够定义区间
        fields = ['brand', 'min_price', 'max_price']
        
#上面的min_price以及max_price为咱们提交数据的key

2.在视图层中导入

from rest_framework.viewsets import ModelViewSet
from django_filters.rest_framework import DjangoFilterBackend
class CarModelViewSet(ModelViewSet):
    queryset = .....
    serializer_class = .....
    filter_class = CarFilterSet #咱们自定义的对象,前提要将其导入到咱们程序所在的窗口
    filter_backends =[DjangoFilterBackend,]

二.排序

from rest_framework.viewsets import ModelViewSet
from rest_framework.filters import OrderingFilter
class CarModelViewSet(ModelViewSet):
    queryset = .....
    serializer_class = .....
    ordering_fields = ['字段一名称','字段二名称'] #能够用()包裹,写前面的优先级大于后面
    filter_backends =[DjangoFilterBackend,]
