Unfortunately I have no expirience in screencasting, and my English is buggy.
Debugging/logging tool is very useful thing for web development. I really like this one in Symfony framework (it is included to Symfony and made with JavaScript, screenshot - http://www.symfony-project.org/blog/2008/08/27/new-in-symfony-1-2-customize-the-web-debug-toolbar). For Django there is third-party module Django Debug Toolbar (http:// rob.cogit8.org/blog/2008/Sep/19/introducing-django-debug-toolbar/). I think the most valuable things that this type of tools can show for developer are: accessible report to server-side logs pre request, info about queries executed during request and maybe some cache stats and variables list. Firebug (http://getfirebug.com/) is the most popular Firefox extension for web developent, very handy and well-built. It implements JavaScript console, DOM traversing, JS-debugging and lot more. FirePHP (http://www.firephp.org/) is another extension that uses Firebug interface and resources and therefore requires Firebug for work. You can see demo here (Firefox with both extensions required, open and enable Firebug console to see output) - http://www.firephp.org/Examples/PHPArchitect/. In two words, FirePHP allows you to output log messages that you passed from PHP code, displays executed db queries, stack trace of exceptions, etc. It requires of using PHP class FirePHPCore/ FirePHP.class.php. Firepy (documentation and screenshot - http://code.google.com/p/firepy/wiki/Documentation) is the implementation for Python of the server-side FirePHP library, but it uses the same Firefox extension (FirePHP). And it includes Middleware for using with Django, but you can easily adopt it for any Python framework. How-to for using FirePHP with web2py: 1) Open Firefox, install Firebug, FirePHP addons: https://addons.mozilla.org/ru/firefox/addon/1843, https://addons.mozilla.org/en-US/firefox/addon/6149. Restart browser. 2) Download http://www.box.net/shared/dtm0dhgze9 and extract 'firepy' folder. 3) Open directory with your current web2py application, and copy 'firepy' folder into 'modules' directory of application. 4) Edit first file in 'models' folder in your application (via web- or desktop-editor). Place these lines in top of the file: import sys sys.path += ['applications/%s/modules' % request.application] from firepy.web2py import start_firepy start_firepy(globals()) 5) Edit some controller file and add this line to some controller function: logging.debug([1, {"asdf":(123, 2, "3")}, "3"]) 6) Click on bug icon on bottom status line of Firefox. This will bring up panel. Check the checkbox "Console" and click "Apply settings". Ensure that tab "Console" is showing. 7) Navigate from browser to this application/controller/function. And now you should see your logging output in console ([1, {"asdf":(123, 2, "3")}, "3"]). If controller executes some db queries, then console will contain some info about them (sample screenshot http://firepy.googlecode.com/files/firepy.png). This is very interesting to know raw SQL-queries (especially for eduction, and for finding redundant or duplicating queries). Notice: Logs shows only if you are autorized in admin application. This check prevents from showing debugging logs for non- administrators. One disadvantage of this way is that it requires Firefox. But if you open your site in other browsers no errors will occur (logging info passes via HTTP headers). One possible way to support other browsers is to use Firebug Lite (pure JS implementation of extension) for them (http://getfirebug.com/lite.html) and modify or extend its code for adding FirePHP functionality. BTW, web2py is great, I really was charmed with it. It is most pytonic web framework and more flexible than most of them (I think it beats Django as well). Such debugging possibility will be a nice addition for it. On 3 июн, 08:10, mdipierro <mdipie...@cs.depaul.edu> wrote: > I am new to this.
