环境搭建
python == 3.6
Django == 2.0
创建工程
django-admin startproject MxShop
配置setting.py文件
# 数据库
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'mxshop', #数据库名字
'USER': 'root', #账号
'PASSWORD': '123456', #密码

'PORT': '3306', #端口
#因为后面第三方登录时，要求引擎为INNODB
"OPTIONS":{"init_command":"SET default_storage_engine=INNODB;"}
}
}
# 使用中文
LANGUAGE_CODE = 'zh-hans'
TIME_ZONE = 'Asia/Shanghai'
USE_I18N = True
USE_L10N = True
USE_TZ = False
# 静态文件路径(须在根目录下创建static目录)
STATIC_URL = '/static/'
STATICFILES_DIRS = (
os.path.join(BASE_DIR, 'static'),
)
安装djangorestframework
pip install djangorestframework
pip install markdown # Markdown support for the browsable API.
pip install django-filter # Filtering support
安装其它的插件
mysql插件地址https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysqlclint,自行下载
pip install mysqlclient-1.3.12-cp36-cp36m-win_amd64
pip install pillow
新建两个python package
- extra_apps （扩展的源码包）
- apps （放所有app）
新建两个文件夹
- media （保存图片）
- db_tools （数据库相关）
把extra_apps和apps添加到sys.path中
# settings.py
import sys
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.insert(0,BASE_DIR)
sys.path.insert(0,os.path.join(BASE_DIR, 'apps'))
sys.path.insert(0,os.path.join(BASE_DIR, 'extra_apps'))
models 设计
首先安装xadmin和DjangoUeditor
安装方法参考之前的在线教育系统
python manage.py startapp users
python manage.py startapp goods
python manage.py startapp trade
python manage.py startapp user_operation
