基础命令 

一、新建项目

二、配置

三、运行

Bootstrap下载

jQuery下载

基础命令 

#创建项目
django-admin startproject [项目名称]
#创建app应用
python manage.py startapp [app名称]
#运行
python manage.py runserver [端口号]
#创建数据模型和数据表结构
python manage.py makemigrations  
python manage.py migrate

一、新建项目

D:\DATA\PycharmProjects>django-admin startproject day
D:\DATA\PycharmProjects>cd day
D:\DATA\PycharmProjects\day>python manage.py startapp app01

新建static、css、img、js、plugins、templates

将bootstrap-3.4.1-dist放入plugins中，把jquery-3.6.0.js放入js中 

创建数据库day

写好models.py后需要在终端输入

D:\DATA\PycharmProjects\day>python manage.py makemigrations  
D:\DATA\PycharmProjects\day>python manage.py migrate

练习文件结构

二、配置

1.settings.py

#添加app应用
'app01.apps.App01Config'

#数据库设置

        'USER': 'root',
        'PASSWORD': 'xxxx',
        'HOST': 'localhost',
        'PORT': 3306,
    }
}
