I want my custom made Django command to be executed every minute. However it seems like python /path/to/project/myapp/manage.py mycommand doesn\'t seem to work
If you want your Django life a lot more simple, use django-command-extensions within your project:
http://code.google.com/p/django-command-extensions/
You'll find a command named "runscript" so you simply add the command to your crontab line:
****** root python /path/to/project/myapp/manage.py runscript mycommand
And such a script will execute with the Django context environment.
