PyCharm创建django项目

 

前提条件:

需要安装django，可以参考如下连接:

1.创建项目

 

 

发现报错误:

 

 解决办法:

2.查看版本
python -m django --version

 

 

3.启动项目
python manage.py runserver

 

解决办法:
找到 seetings.py 文件,然后在settings.py文件头加上:import os

继续启动

python manage.py runserver

 

4.修改settings.py

修改结果如下:

ALLOWED_HOSTS = ['*']

DEBUG = False

 

5.解决告警问题

Ctrl+C停掉后执行
python manage.py migrate

 

说明:

1.创建项目的同时会自动创建一个与项目名相同的app,该app名称是可以修改的，但是修改后需要修改配置文件settings.py的配置项:ROOT_URLCONF

2.启动的时候可以本机的ip和指定端口,如下:

python manage.py runserver 192.168.1.102:8080

 

或是修改manae.py文件，指定ip和端口
