Django-1.3的helloworld和1.2.1下载

django各种版本的下载 比如1.2.1
http://code.djangoproject.com/svn/django/tags/releases/1.2.1/


1.安装python2.6后（2.7好像db插件没有exe版本的，不好装），下载Django-1.3.tar.gz
比如目录为E:\java\python\Django-1.3
2.python setup.py install之后会在C:\Python27\Lib\site-packages中建个目录django
设置E:\java\python\Python26\Lib\site-packages\django\bin到path环境变量
3.随便找个地方比如D:\java\python\workspace\work1>
运行django-admin.py startproject mysite

E:\java\python\workspace\work1\mysite>tree /F
文件夹 PATH 列表
卷序列号为 1ECF-E5A4
D:.
    manage.py
    settings.py
    urls.py
    __init__.py
    
没有子文件夹 

工程名尽量不要用django或test等python内建的名称

python manage.py runserver

http://localhost:8000/

python manage.py runserver 8080  可以更改端口
python manage.py runserver 0.0.0.0:8080  可以更改ip，别人的机器，没试验

如果想连mysql数据库
配置setting.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'test',                      
        'USER': 'root',                     
        'PASSWORD': 'haoning',                
        'HOST': 'localhost',                    
        'PORT': '3306',                      
    }
}

再启动报错:django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named MySQLdb
还需要装驱动，就像java的jar驱动一样
到http://www.djangoproject.com/r/python-mysql/ 下载MySQL-python-1.2.3.tar.gz
这个不好使，似乎还要装别的，改用MySQL-python-1.2.2.win32-py2.6.exe（http://sourceforge.net/projects/mysql-python/forums/forum/70460/topic/2316047?message=5613887）
附件中大的jpg改成exe使用，自动安装
参考http://pqcc.iteye.com/blog/511588 虽然和我的版本有点出入
把附件中的小的jpg去掉jpg后缀，改成rar，解压到两个dll文件放到E:\java\python\Python26\Lib\site-packages\MySQLdb\下，那个__init__.py修改
34行：

#from sets import ImmutableSet
#class DBAPISet(ImmutableSet):
class DBAPISet(frozenset):

去掉两行加一行
修改E:\java\python\Python26\Lib\site-packages\MySQLdb\converters.py
把两个大写变成小写
129行改成
set: Set2Str,
45行改
def Str2Set(s):
return set([ i for i in s.split(',') if i ]) 
去掉第37行：
#from sets import BaseSet, Set
如果python manage.py runserver还有问题，就删掉E:\java\python\Python26\Lib\site-packages\MySQLdb下面的所有pyc文件，只留py文件

E:\java\python\workspace\work1\mysite>python manage.py syncdb

将会在mysql中

E:\java\python\Python26\lib\site-packages\MySQLdb\__init__.py:34: DeprecationWarning: the sets module is deprecated

工程创建完了，开始创建子应用app
python manage.py startapp polls

E:\java\python\workspace\work1\mysite>tree /F
卷 back 的文件夹 PATH 列表
卷序列号为 0A16-ED1C
E:.
│  manage.py

│  settings.pyc
│  urls.py

│  __init__.py

└─polls
        models.py
        tests.py
        views.py
        __init__.py
        

E:\java\python\workspace\work1\mysite>

  
修改models.py

from django.db import models

class Poll(models.Model):
    question = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')

class Choice(models.Model):
    poll = models.ForeignKey(Poll)
    choice = models.CharField(max_length=200)
    votes = models.IntegerField()

把poll模块加入到settings.py

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'polls'
    # Uncomment the next line to enable the admin:
    # 'django.contrib.admin',
    # Uncomment the next line to enable admin documentation:
    # 'django.contrib.admindocs',
)

根据模块生成sql语句

E:\java\python\workspace\work1\mysite>python manage.py sql polls
E:\java\python\Python26\lib\site-packages\MySQLdb\__init__.py:34: DeprecationWarning: the sets module is deprecated
  from sets import ImmutableSet
BEGIN;
CREATE TABLE `polls_poll` (
    `id` integer AUTO_INCREMENT NOT NULL PRIMARY KEY,
    `question` varchar(200) NOT NULL,
    `pub_date` datetime NOT NULL
)
;
CREATE TABLE `polls_choice` (
    `id` integer AUTO_INCREMENT NOT NULL PRIMARY KEY,
    `poll_id` integer NOT NULL,
    `choice` varchar(200) NOT NULL,
    `votes` integer NOT NULL
)
;
ALTER TABLE `polls_choice` ADD CONSTRAINT `poll_id_refs_id_5d896c23` FOREIGN KEY (`poll_id`) REFERENCES `polls_poll` (`id`);
COMMIT;

可以刷到mysql里面；
验证
python manage.py validate
python manage.py sqlcustom polls
python manage.py sqlclear polls
python manage.py sqlindexes polls
python manage.py sqlall polls
这些都是查看sql语句

再运行 python manage.py syncdb就又在数据库里生成了
polls_choice,polls_poll  两个表

在有工程的环境变量下使用命令行

python manage.py shell
>>> import polls
>>> dir(polls)
['__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__', 'models']
>>> 

django-admin.py help  查看帮助

已经看到E:\java\python\Django-1.3\docs\intro\tutorial01.txt的558行
下次继续吧
