AttributeError: type object ‘BookAPIView‘ has no attribute ‘get_extra_actions‘

django-rest-framework开发时报错 如下：

。。。。。。
File "/Users/user/Desktop/PythonProject/django_restful_drf/venv/lib/python3.9/site-packages/rest_framework/routers.py", line 236, in get_urls
    routes = self.get_routes(viewset)
  File "/Users/user/Desktop/PythonProject/django_restful_drf/venv/lib/python3.9/site-packages/rest_framework/routers.py", line 152, in get_routes
    extra_actions = viewset.get_extra_actions()
AttributeError: type object 'BookAPIView' has no attribute 'get_extra_actions'

报错分析：

views.py的类视图函数不是继承自视图集ViewSet，而路由使用的是router拼接，所以不支持

解决：

方法1. 把路由改为普通格式：

from django.conf.urls import url
from . import views

urlpatterns = [
    url(r'^books/$', views.BooksAPIView.as_view()),
    url(r'^books/(?P\d+)/$', views.BookAPIView.as_view()),
]

方法2. 视图函数继承自视图集ViewSet：

from rest_framework import viewsets

class BooksAPIView(viewsets):
	...

如有不足，欢迎指正！
