How do I migrate a model out of one django app and into a new one?
There's a django app called django-debug-toolbar which adds a little toolbar at the top of all django served pages providing info related to the backend of the page's rendering, such as how many queries were executed, how much time they each took, etc.

WMD in Django Admin?
It also prints out signals.

I don't use signals in my app, so I have never used that feature, but it's there..


I wrote little command that shows all signal listeners: You can modify it to show signals only..
