I've been reading and trying to figure out the best way to implement scheduled background tasks in PythonAnywhere. I think I understand the basics and challenges, but I still think I'm missing something.
I haven't found a reasonable way to use web2py scheduler directly in PythonAnywhere. Is it possible? When using script with my own loop, I'm having either issues with timeout (might take several minutes before I check db again) or when manually refreshing DAL with auto_import=True, the db variables are not imported, only table names (I have few pickle filters). I want to have a background task, which checks the database and sends emails if necessary. PythonAnywhere offers min 1 hour interval for scripts, and my script should be more responsive (varies from 30 seconds to 15 minutes). Currently I've made an hourly scheduled python script, which never ends (while loop), checks the database and then sleep variable time, if nothing is found. It updates a file so that when PythonAnywhere tries to start a new process again (hourly), it will not start another instance as the previous script is still ok. This works fine and I use the web2py environment to load all model information and so on (e.g. python web2py.py -S app -M -R applications\app\modules\script.py). But that command loads the models only once and if I sleep 15 minutes, the db connection is lost. I tried to search if web2py has something like db.reconnect() by could'nt found anything. P.s. I do have to say that PythonAnywhere rocks for a small developer like my (as well as we2py).
