  • 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
