windows10 -- mysql5.5 + python3.4 + django1.11 +pycharm2016.2 + PyMySQL(DB DRIVER) 环境搭建

环境介绍

2016-07-2513:32:26

 

name	value	comment
OS	win10	操作系统
python	python3.4	python主程序
IDE	pycharm:  201.2	python IDE集成开发环境
框架	django:  1.11	web开发框架，类似与Struts（JAVA）
DB	mysql: 5.5	(在centos 上使用二进制安装，你可以直接安装在win10上面)    ----- 一款nc的开源数据库
connector	PyMySQL	python connector

 

 

 

 

作者一路飘来的坑

这就是自己探索的代价，一个小问题都可能停滞1天，或者2天，或者一周

但是，这就是探索的乐趣所在

•   pycharm 无法创建django project，只能创建pure python
  • 　　因为pycharm的community版本没有，需要下载professional版本，要注册码，自己百度搞定
•   python死活连接不上mysql   ----  django内置了sqlite，无需安装，直接使用，但是生产环境一般还是使用mysql，所以这个问题必须解决
  • 　　需要再windows上下载一个DBdriver，我的理解就是一个客户端去驱动连接数据库，python不能直接连接，毕竟db认sql语言，不认识python对吧
  •      看介绍：可以安装mysqlclient,connector/python，其实都有问题，因为python3.4太新了(20160725)，使用pymysql代替

 

软件下载

1. python: python3.4      www.python.org  这个如果都找不到就不要学python了
2. pycharm:  2016.2        http://www.jetbrains.com/pycharm/download/#section=windows  这个注意，请下载 professional 版本
3. django:  1.11              https://www.djangoproject.com/download/      可以源码安装，也可以pip 安装
4. mysql: 5.5(在centos 上使用二进制安装，你可以直接安装在win10上面)
5. connector: PyMySQL    git clone https://github.com/PyMySQL/PyMySQL  如果不熟悉git，可以直接打开后面的网址在网页端下载

软件安装

python   

　　下一步，下一步，一下到底，安装位置作者放在了   C:\Python34

pytharm

　　下一步，下一步，一下到底

django

　　方式1   将源代码解压，放到C盘下面吧-----win+r-----cmd---cd c:\dj  ---- python setup.py

　　方式2    ---win+r-----cmd-----pip install django=1.9.2   建议安装这个版本（20160725）

mysql5.5

　　方式1 下载windows版本的installer ,一下到底

　　方式2  使用centos6.5，然后下载bin版本的安装（作者采用的方式）

PyMySQL

　　安装方式和django差不多，进入windows的cmd界面，cd到软件解压目录，然后 python setup.py install 

 

django和pymysql都会安装下面的目录

C:\Python34\Lib\site-packages

 

 

 

创建工程

 ..1 new---new project

建立好的工程目录类似这个样子

这里可以再多建立几个APP

到现在为止基本的矿机已经完成了，恭喜我自己

 

..2 让django跑起来

点击工具栏的run

然后在本地打开浏览器输入:    http://127.0.0.1:8000/admin

没错，你就成功了，这个系统已经跑起来了，并且你看见了django非常强大的自动生成的一个后台管理界面

 

 

..3 让django连接上数据库mysql

..3.1 常见数据库的model

 1 class UserInfo(models.Model):
 2     name = models.CharField(max_length=32)
 3     email = models.CharField(max_length=32)
 4     comment = models.CharField(max_length=32)
 5     age = models.IntegerField()
 6     password = models.CharField(max_length=32,default="123456")
 7 
 8     # def __str__(self):
 9     #     s = {"id": self.id, "name": self.name, "email": self.email}
10     #     return s
11     def __str__(self):
12         return self.name

projectname/appname/models.py

 

 ..3.2 配置数据库连接

/projectname/settings.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'django_db',
        'USER':  'root',
        'PASSWORD': '123456',
        'HOST': '192.168.202.104',
        'PORT': '3306',
    }
}
..3.3 初始化安装你的app
注意后面一定要有逗号，app01 and app02 就是作者自己建立的两个app， 我使用app02,稍后你可以看见设置

 

 

 1 INSTALLED_APPS = [
 2     'django.contrib.admin',
 3     'django.contrib.auth',
 4     'django.contrib.contenttypes',
 5     'django.contrib.sessions',
 6     'django.contrib.messages',
 7     'django.contrib.staticfiles',
 8     'app01',
 9     'app02',
10 ]

 

 

 ..3.4 在数据库中建表

manage.py这个时候可以登场了

使用pycharm提供的terminal

python manage.py makemigrations

python manage.py migrate

如果一切正常，你已经在数据库中建表格了，如果有意外，你可以在数据库中先建好db,然后使用这两条命令插入表

..3.5 编写代码对数据库进行增删改查，使用ORM

..3.5.1

 views会去models里面去取数据

 1 from django.db import models
 2 
 3 # Create your models here.
 4 
 5 
 6 class UserInfo(models.Model):
 7     name = models.CharField(max_length=32)
 8     email = models.CharField(max_length=32)
 9     comment = models.CharField(max_length=32)
10     age = models.IntegerField()
11     password = models.CharField(max_length=32,default="123456")
12 
13     # def __str__(self):
14     #     s = {"id": self.id, "name": self.name, "email": self.email}
15     #     return s
16     def __str__(self):
17         return self.name
18 
19 
20 class Reporter(models.Model):
21     name = models.CharField(max_length=32)
22 
23     def __str__(self):

27 class Article(models.Model):
28     pub_date = models.DateField()
29     headline = models.CharField(max_length=32)
30     content = models.TextField()
31     reporter = models.ForeignKey(Reporter)
32 
33     def __str__(self):
34         return self.headline

好了，现在运行吧

在浏览器里面输入

http://127.0.0.1:8000/app02/db/select

后台查出来的数据也是这个
