Django+Vue打造購物網站(一)

環境搭建

python == 3.6
Django == 2.0

創建工程

django-admin startproject MxShop

配置setting.py文件

# 數據庫
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'mxshop',        #數據庫名字
        'USER': 'root',          #賬號
        'PASSWORD': '123456',      #密碼
        'HOST': '127.0.0.1',    #IP
        'PORT': '3306',                   #端口
        #因為后面第三方登錄時，要求引擎為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


# 靜態文件路徑(須在根目錄下創建static目錄)

STATIC_URL = '/static/'
STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'static'),
)

安裝djangorestframework

pip install djangorestframework
pip install markdown       # Markdown support for the browsable API.
pip install django-filter  # Filtering support

安裝其它的插件
mysql插件地址https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysqlclint,自行下載

pip install mysqlclient-1.3.12-cp36-cp36m-win_amd64
pip install pillow

新建兩個python package

• extra_apps （擴展的源碼包）
• apps （放所有app）

新建兩個文件夾

• media （保存圖片）
• db_tools （數據庫相關）

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 設計

首先安裝xadmin和DjangoUeditor
安裝方法參考之前的在線教育系統

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