跟着您的教学步骤执行 想问id 要在mysql 开auto_increment吗 ？因为我在编辑和删除的时候抓不到资料 谢谢您

python manage.py migrate sims

why only 2 tables are created:
diango_migrations , sims_Student

C:\Users\wue\PycharmProjects\sms>python manage.py makemigrations sims
No changes detected in app 'sims'

C:\Users\wue\PycharmProjects\sms>python manage.py migrate sims
Operations to perform:
Apply all migrations: sims
Running migrations:
Applying sims.0001_initial... OK

学生信息新增， 修改 ，删除， 处理函数

怎么会每个函数都得放 database connection string 啊？！

conn = MySQLdb.connect(host="localhost", user="root", passwd="123456", db="sms", charset='utf8')

你好，我这边在数据库插入数据能正常显示，但是在网页增删改查就提示404
The current path, sims/add, didn't match any of these.
这是什么原因？

C:\Users\myname\PycharmProjects\sms>python manage.py startapp sims
Traceback (most recent call last):
File "manage.py", line 10, in main
from django.core.management import execute_from_command_line
