32-搜索后台接口

搜索后台接口

一、流程

'''
# 后端	
	1. 模糊匹配: SearchFilter
	2. 自己写: 自定义过滤类, 继承filter_queryset, 指定'字段__contains', return queryset
	3. 搜索接口: 不和课程一起, 坨到一起了
		CourseSearchView 继承 G/L
		内部书写SearchFilter的即可
		提示: 需要携带分页
	4. 配置路由: search
'''

二、路由：course/urls.py

router.register('search',views.CourseSearchView,'search')

三、视图：course/views.py

from rest_framework.viewsets import GenericViewSet
from rest_framework.mixins import ListModelMixin
from rest_framework.filters import SearchFilter
from . import models, serializers
from .filters import CourseFilter

# 搜索课程接口
class SearchCourseViewSet(ListModelMixin, GenericViewSet):
    queryset = Course.objects.filter(is_delete=False, is_show=True).order_by('orders')
    serializer_class = CourseModelSerializer

    # 提示: 需要携带分页
    pagination_class = PageNumberPagination

    # 自定义
    # filter_backends = [CourseFilter]

    # 使用SearchFilter
    filter_backends = [SearchFilter]
    search_fields = ['name']
