process of starting a djangoe project

1. use django-admin startproject **projectname** to create an empty project
2. use github to store the project
3. use python3 manage.py runserver 0.0.0.0:8000 to run the server
4. add **ip_address** to ALLOWED_HOSTS in setting.py

• we can use ag ALLOWED_HOSTS to find the path and line of that name

5. we don't want __pycache__ to be uploaded to github so we create a file '.gitignore' to myapp/ and add '**/pycache' to the file.

Adding a new app with Django

• use python3 manage.py startapp **game**

Migrate the update to the server:

• run python3 manage.py migrate to update

Create a superuser to the admin site

• run python3 manage.py createsuperuser.

Making python folder able to be imported:

• add a 'init.py' to the folder

Setting timezone:

• change the string after TIMEZONE in setting.py to Asia/Shanghai

The structure of the project as a whole:

####程序运行逻辑：

1. 用户与前段javascript交互js监听函数返回一个路由
2. 返回的路由有django中的url进行处理后返回对应的views哪的函数
3. views内部函数负责处理传过来的值以及后端逻辑#程序运行逻辑：
