Django+Vue打造购物网站(一)

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
        'HOST': '127.0.0.1',    #IP
        '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
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',

    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'rest_framework',
    'users',
    'user_operation',
    'trade',
    'goods',
    'xadmin',
    'DjangoUeditor',
    'crispy_forms',    
]
