 [Django]数据库 API 参考
软件技术
lhwork 发表于 2007/2/3 13:40:42 |
一旦 数据模型 创建完毕, 自然会有存取数据的需要.本文档介绍了由 models 衍生而来的数据库抽象API,及如何创建,得到及更新对象.
贯穿本参考, 我们都会引用下面的民意测验(Poll)应用程序:
class Poll(models.Model):
slug = models.SlugField(unique_for_month='pub_date')
question = models.CharField(maxlength=255)
pub_date = models.DateTimeField()
expire_date = models.DateTimeField()
def __repr__(self):

[Django]Apache 基于 Django 用户数据库进行授权
软件技术
lhwork 发表于 2007/2/3 13:39:50 |
| Apache 保持多种授权数据库同步一直有些问题, 你可以配置Apache 直接使用 Django 的 authentication system . 举例来说,你可以:
让 Apache 只对授权用户提供媒体文件服务.授权拥有特定权限的用户访问 Subversion 库.允许特定用户连接到由 mod_dav 创建的 WebDAV share.

[Django]Django 缓存框架
软件技术
lhwork 发表于 2007/2/3 13:39:02 |
动态网站的基本功能就在于, 没错, 它是动态的. 用户每次请求一个页面时, Web 服务器都要进行全面的计算 --
从数据库查询到渲染业务逻辑 -- 直到生成最终展示的页面. 从服务器负载的角度来看,这远比仅仅从文件系统读取一个文件展示要占用的系统资源多得多.
对绝大多数网站应用程序来说, 这点负载不是大问题.绝大部分网站应用不是 washingtonpost.com 或
slashdot.org 这样繁忙; 它们通常是小规模-中等规模的,没有特别高的点击率. 但对大规模高点击率的站点来说,
就应该尽可能的降低WEB服务器的负载.
这正是需要缓存机制的原因.
建立缓存机制的目的就是在适当的时候省略掉计算步骤(再次访问时).下面用伪码来阐述该机制如何运作:
根据 URL 请求, 看看缓存中有没有该页面
如果缓存中有该页面:
返回该页面
否则:
生成该页面
将该页面保存在缓存中(以备下次访问)
返回这 |

[Django]Using Django's TemplateTags
软件技术
lhwork 发表于 2007/2/3 11:51:15 |
| I've had a number of e-mails about how I include the listing of blog
tags and archives by month on the side of my website from people who
have obviously built up a blog and now want further integration with
their website.
Well, it's ultra-simple thanks to a nifty Django feature called template tags.
The concept behind template tags is simple - a quick snippet of |

[Django]django with apache2
软件技术
lhwork 发表于 2007/2/3 11:46:21 |
| One thing that I feel is harder than it should be with django is
getting it working with Apache2. Sure the built in webserver is nice
for development, but there comes a time when you need to step up and
use a webserver for development that you can also deploy the site upon.
I have used Apache a lot in the past, but recently I have decided to move over to installing everything the Debian
way, and this will reflect that. I am goin |
