I am trying to run a Django management command from cron. I am using virtualenv to keep my project sandboxed.
I have seen examples here and elsewhere that show running management commands from within virtualenv’s like:
0 3 * * * source /home/user/project/env/bin/activate && /home/user/project/manage.py command arg
However, even though syslog shows an entry when the task should have started, this task never actually runs (the log file for the script is empty). If I run the line manually from the shell, it works as expected.
The only way I can currently get the command to run via cron, is to break the commands up and put them in a dumb bash wrapper script:
#!/bin/sh
source /home/user/project/env/bin/activate
cd /home/user/project/
./manage.py command arg
EDIT:
ars came up with a working combination of commands:
0 3 * * * cd /home/user/project && /home/user/project/env/bin/python /home/user/project/manage.py command arg
At least in my case, invoking the activate script for the virtualenv did nothing. This works, so on with the show.
