So I've been meaning to create a cron job on my prototype Flask app running on Heroku. Searching the web I found that the best way is by using Flask-Script but I fail to see the point of using it. Do I get easier access to my app logic and storage info? And if I do use Flask-Script, how do I organize it around my app? I'm using it right now to start my server without really knowing the benefits. My folder structure is like this:
/app
/manage.py
/flask_prototype
all my Flask code
Should I put the 'script.py' to be run by the Heroku Scheduler on app folder, the same level as manage.py? If so, do I get access to the models defined within flask_prototype?
Thank you for any info
Flask-Script just provides a framework under which you can create your script(s). It does not give you any better access to the application than what you can obtain when you write a standalone script. But it handles a few mundane tasks for you, like command line arguments and help output. It also folds all of your scripts into a single, consistent command line master script (this is manage.py
, in case it isn't clear).
As far as where to put the script, it does not really matter. As long as manage.py
can import it and register it with Flask-Script, and that your script can import what it needs from the application you should be fine.
