项目所需要的第三方库

  • python版本：python 3.5
  • pip安装的第三方库（重要的，需要注意的已经用红色方框标明）

python django 项目搭建到部署_redis

  • 其中Django1.8.2最高兼容python3.5，如果安装了python更高版本，则对应的Django版本也需要更高。
  • redis版本和celery也存在一定的兼容关系，已知celery最新版本（4.4）对应的redis版本最低为3.2.0，而安装了更低版本的celery，如图中的3.1.25则对redis的版本也有要求，3.1.25的cerely在异步发送邮件时（后续会说明），redis3.0及以上的版本都会报错，所以这里使用了redis2.8.0

Django项目框架搭建

1.文件目录

python django 项目搭建到部署_django_02

python django 项目搭建到部署_redis_03

其中：db文件夹存放模型类的基类，其他的模型类继承该BaseModel类，代码如下：

from django.db import models


class BaseModel(models.Model):
    '''模型抽象基类'''
    create_time = models.DateTimeField(auto_now_add=True, verbose_name='创建时间')
    update_time = models.DateTimeField(auto_now=True, verbose_name='更新时间')
    is_delete = models.BooleanField(default=False, verbose_name='删除标记')

    class Meta:
        # 说明是一个抽象模型类
        abstract = True

2.manage.py常用指令：

python manage.py startapp appname
python manage.py makemigrations
python manage.py migrate
python manage.py runserver

3.setting.py

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
import os
import sys

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.insert(0, os.path.join(BASE_DIR, 'apps'))
# 项目的应用存放在apps目录下，加上这行代码，在之后需要用到应用时，可以不带上前面的apps

4.项目的urls和应用的urls

项目的urls：

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^tinymce/', include('tinymce.urls')), # 富文本编辑器
    url(r'^user/', include('user.urls', namespace='user')), # 用户模块
    url(r'^cart/', include('cart.urls', namespace='cart')), # 购物车模块
    url(r'^order/', include('order.urls', namespace='order')), # 订单模块
    url(r'^', include('goods.urls', namespace='goods')), # 商品模块
]

其余应用的urls通过后面的代码展示

5.python与数据库交互，需要在__init__.py中加上两行代码，其中pymysql库需要安装后使用

import pymysql
pymysql.install_as_MySQLdb()

6.模型类代码：

from django.db import models

# Create your models here.


# 暂无模型

from django.db import models
from db.base_model import BaseModel

7.执行迁移命令，在数据库生成对应的数据表，最后启动服务器，验证是否正确运行。
