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

[编辑] 安装指南

获得 quixote http://quixote.python.ca/releases/Quixote-2.4.tar.gz
tar zxvf Quixote-2.4.tar.gz
cd Quixote-2.4 

python -c "import os, quixote; print os.path.dirname(quixote.__file__)"  // 检查是否已有quixote安装
python setup.py install  // quixote 安装到 :/usr/lib/python2.3/site-packages/quixote 
若出现 error: invalid Python installation: unable to open /usr/lib/python2.3/config/Makefile (No such file or directory)
请安装 #apt-get install python2.3-dev
或 /usr/local/lib/python2.4/site-packages/quixote/server/  // 使用了 Python 2.4
或 /usr/local/lib/python2.5/site-packages/quixote/server/ // 使用了 Python 2.5

http://localhost:8080
python server/simple_server.py --port 4000
http://localhost:4000

通过mod_python与Apache的整合 

#apt-get install apache2-dev 安装 apxs2 , apxs 针对 Apache 1.x

获得 http://www.apache.org/dist/httpd/modpython/mod_python-3.2.10.tgz 
./configure --with-apxs=/usr/bin/apxs2
make
make install
vi /etc/apache2/sites-enabled/000-default
相关细节: /usr/lib/python2.3/site-packages/quixote/server/mod_python_handler.py
   LoadModule python_module /usr/lib/apache2/modules/mod_python.so
   <LocationMatch "^/quixote(/|$)">
       SetHandler python-program
       PythonHandler quixote.server.mod_python_handler
       PythonOption quixote-publisher-factory quixote.demo.create_publisher
       PythonInterpreter quixote.demo
       PythonDebug On
   </LocationMatch>

/etc/init.d/apache2 restart
http://localhost/quixote

Windows用户 

cd Quixote-2.4
修改 setup.py 
build_extensions = True
python setup.py build_ext --compiler=mingw32 install

通过scgi 

http://www.mems-exchange.org/software/scgi/
python setup.py install
LoadModule scgi_module /usr/local/lib/python2.3/site-packages/mod_scgi.so
<Location "/">
    SetHandler scgi-handler // Apache 2.0 need, Apache 1.3 don't need
    SCGIServer 1localost:3000
    SCGIHandler On
</Location>

[编辑] Quixote Sample

touch miniqx.py 

#!/usr/bin/env python

               Simple Quixote Server
               A <a href="hello">link</a>.

              </body>
              </html>
            
def hello(self):
    return '<html><body>Hello world!

<a href="/">Home</a></body></html>'

def create_publisher():
    return Publisher(RootDirectory(),
    display_exceptions='plain')

if __name__ == '__main__':
    from quixote.server.simple_server import run
    print 'creating demo listening on http://192.168.1.3:8082/'
    run(create_publisher, host='192.168.1.3', port=8082)

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
