* Publisher: maps URLs to Python code
 +
* HTTPRequest, HTTPResponse classes
 +
* Web server interfaces for CGI, FastCGI, SCGI, mod_python
 +
* [[Python Templating Language]] (optional)
 +
* [[Quixote Form Framework|Form framework]] (optional)
 +
 +
[[How Quixote Works]]
 +
==核心原则==
 +
Quixote is built on four core principles:
 +
* Publishing function results: Quixote's main job is using a URL to look up a Python callable (e.g., a function or method) and put its results on the web.
 +
* The URL is part of the user interface, and the organization of source code and URL-space should roughly correspond.
 +
* Embedding HTML in Python is cleaner and easier than embedding Python in HTML. // 类似 Java Servlet
 +
* No magic: when Quixote can't figure out what to do, it refuses to guess the programmer's intent, preferring to raise an exception instead.
 +
 +
==Web Interface==
 +
The web interface to SPLAT! is implemented in the splat.web package, with the following modules:
 +
*splat.web.util      (splat/web/util.ptl)
 +
*splat.web.index    (splat/web/index.ptl)
 +
*splat.web.bug_ui    (splat/web/bug_ui.ptl)
 +
*splat.web.prefs    (splat/web/prefs.ptl)
 +
 +
In fact, there are many useful analogies between a traditional filesystem-based web server (such as Apache) and Quixote's Python-centric way of building a web site.:
 +
{|border="1" cellspacing="0"
 +
|+ '''Table 1'''
 +

天涯何处无芳草，何必单恋一只花了

Quixote is yet another framework for developing Web applications in Python.

对于robust, quixote是经过大规模实际应用检验的, douban.com的主要动力就是它.

在放弃使用Zope后，MEMS Exchange 决定开发 Quixote

若使用 apache, 请事先安装 mod_python 或 mod_scgi

How Quixote Works

[编辑] 核心原则

Quixote is built on four core principles:

  • Publishing function results: Quixote's main job is using a URL to look up a Python callable (e.g., a function or method) and put its results on the web.
  • The URL is part of the user interface, and the organization of source code and URL-space should roughly correspond.
  • Embedding HTML in Python is cleaner and easier than embedding Python in HTML. // 类似 Java Servlet
  • No magic: when Quixote can't figure out what to do, it refuses to guess the programmer's intent, preferring to raise an exception instead.

[编辑] Web Interface

The web interface to SPLAT! is implemented in the splat.web package, with the following modules:

  • splat.web.util (splat/web/util.ptl)
  • splat.web.index (splat/web/index.ptl)
  • splat.web.bug_ui (splat/web/bug_ui.ptl)
  • splat.web.prefs (splat/web/prefs.ptl)

In fact, there are many useful analogies between a traditional filesystem-based web server (such as Apache) and Quixote's Python-centric way of building a web site.:

Table 1
Filesystem (e.g., Apache) Quixote
directory Python namespace (module, package, ...)
file Python callable object (function, method, ...)
index.html _q_index()
file exists, is readable callable object exists, is in _q_exports
