django-drf frame and sorted query component

A relevant

1. fuzzy query

1. Import module assembly

from rest_framework.filters import SearchFilter

2. The custom view class associated setting parameters

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'] #可以用()包裹,写前面的优先级大于后面
    filter_backends = [SearchFilter,]

2. Custom Query

1. import module and custom criteria set

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还是实现分类
        # min_price，max_price可以定义区间
        fields = ['brand', 'min_price', 'max_price']
        
#上面的min_price以及max_price为我们提交数据的key

2. In view of the introduction layer

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

II. Sort

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'] #可以用()包裹,写前面的优先级大于后面
    filter_backends =[DjangoFilterBackend,]
