路飞项目篇：课程详情前后端、搜索前后端、订单表设计及生成订单接口、this.$router补充
1 课程详情接口
class CourseView(GenericViewSet, ListModelMixin,RetrieveModelMixin):
queryset = Course.objects.all().filter(is_delete=False, is_show=True).order_by('orders')
serializer_class = CourseSerializer
pagination_class = CommonPageNumberPagination
# 按课程分类过滤
filter_backends = [OrderingFilter, DjangoFilterBackend]
filter_fields = ['course_category']
ordering_fields = ['id', 'price', 'students']
2 课程章节列表接口(查所有)
# 过滤---》根据课程id过滤章节
路由
# api/v1/course/coursechapter/
router.register('coursechapter', views.CourseChapterView, 'coursechapter')
视图类
class CourseChapterView(GenericViewSet, ListModelMixin):
queryset = CourseChapter.objects.all().filter(is_delete=False, is_show=True).order_by('orders')
serializer_class = CourseChapterSerializer
filter_backends = [ DjangoFilterBackend]
filter_fields = ['course']
序列化类
class CourseSectionSerializer(serializers.ModelSerializer):
class Meta:
model=CourseSection
# 课时名字，课时顺序，课时视频地址，视频时长，是否可试看
fields = ('name', 'orders', 'section_link', 'duration', 'free_trail')
class CourseChapterSerializer(serializers.ModelSerializer):
# 子序列化---》课时是多条--》一定要加many=True
coursesections=CourseSectionSerializer(many=True)
class Meta:
model=CourseChapter
# coursesections:1 表模型中写 2 序列化类中写 3 子序列化
# 章节id，章节名字，第几章，章节介绍，章节下所有课时
fields=['id','name', 'chapter', 'summary', 'coursesections']

8 生成订单接口
# 下单---》用户要登录---》认证类（自己写，使用内置的：认证类，权限类）
# 前端携带数据发送post请求到后端----》生成订单(待支付状态)，生成支付链接---》把支付链接返回给前端---》重定向到支付链接（支付宝地址）--->等待用户支付
# 前端提交的数据格式：
{courses:[1,2],total_amount:'99',pay_type:1,subject:很多课程}
