Winpdb, awesome debugger.. needs emacs interface tho..

 After working with horrible php but the awesome xdebug+geben for emacs, I finally found an equivalent for python: winpdb and rpdb2.

In your code all you need is

import rpdb2; rpdb2.start_embedded_debugger('asdf',fAllowRemote=True)

where 'asdf' is just some password you come up with so that other users can't start debugging on your code.

Then start winpdb, navigate to file->attach, enter the password you chose, point it at your host and then debug away.

Great!

Emacs, geben and xdebug

* sudo pecl install xdebug
* edit php.ini

  zend_extension=/path/to/xdebug.so
; usually /usr/lib/php5/20060613+lfs/xdebug.so
  [debug]
  xdebug.remote_autostart=off
  xdebug.remote_enable=on
  xdebug.remote_handler=dbgp
  xdebug.remote_mode=req
  xdebug.remote_host=localhost
  xdebug.remote_port=9000

* restart apache: /etc/init.d/apache2 restart
* download geben: http://trac.sakura.ne.jp/geben/
* unpack it into ~/emacs.d/ (emacs includes folder) * add this to your .emacs file:

(add-to-list 'load-path "/home/your/emacs.files/geben")
(add-to-list 'load-path "/home/your/emacs.files/geben/gud")

* restart emacs and run geben with `M-x geben`
* open a php service with the parameter
`?XDEBUG_SESSION_START` to start debugging

Difficult errors to debug in Django for Django noobs..

Got this as an debug template page today:

TemplateSyntaxError at /admin/

Caught an exception while rendering: name 'User' is not defined

After some digging around and frustration, I finally figured it out. I had created a new app for my project called `newsbin`, then created a model and views and set the views up in urls.py, but I had not yet added `newsbin` to the installed apps section of settings.py. Thus it gave the above error.

Stupid Adventures in Djangoland

After converting a project and doing some directory wide find-replace's, I kept getting this error in django:

TemplateSyntaxError at /admin/ Caught an exception while rendering: maximum recursion depth exceeded

A little background, all my projects are usually named 'backend', with the front end code (usually flash) in a separate directory 'frontend'. So for example in settings.py, I install apps in django by adding 'backend.app' to INSTALLED_APPS. Anyway, after commenting out huge chunks of code I eventually turned to one of the last things I could turn to to start commenting stuff out. So things Amongst the urlpatterns I found a line (r'^app/', include('backend.urls')). Some how, after the find-replace session, this line was setup to constantly reference the urls.py that it resided in, which resulted in the error stated above.
