Frequent Technical Questions

"Scheduled actions do not run at the exact time they were expected"
|
|
-------------------------------------------------------------------
|
|
|
|
On the Odoo.sh platform, we cannot guarantee an exact running time for scheduled actions.
|
|
|
|
This is due to the fact that there might be multiple customers on the same server, and we must guarantee a fair share of the server for every customer. Scheduled actions are therefore implemented slightly differently than on a regular Odoo server, and are run on a *best effort* policy.
|
|
|
|
.. warning::
|
|
Do not expect any scheduled action to be run more often than every 5 min.
|
|
|
|
Are there "best practices" regarding scheduled actions?
|
|
-------------------------------------------------------
|
|
|
|
**Odoo.sh always limits the execution time of scheduled actions (*aka* crons).**
|
|
Therefore, you must keep this fact in mind when developing your own crons.
|
|
|
|
We advise that:
|
|
|
|
- Your scheduled actions should work on small batches of records.
|
|
- Your scheduled actions should commit their work after processing each batch;
|
|
this way, if they get interrupted by the time-limit, there is no need to start over.
|
|
- Your scheduled actions should be
|
|
`idempotent <https://stackoverflow.com/a/1077421/3332416>`_: they must not
|
|
cause side-effects if they are started more often than expected.

Can you install `pycups <https://pypi.org/project/pycups/>`_ or some similar library linked to `CUPS <https://www.cups.org/>`_ ?
|
|
--------------------------------------------------------------------------------------------------------------------------------
|
|
|
|
Several community apps for Odoo list ``pycups`` as required dependency.
|
|
|
|
- ``pycups`` is a set of Python bindings for the libcups library. They are meant to integrate your computer with a local printing server.
|
|
- CUPS is a printing server meant to be used for printers on the same local network as the Odoo server.
|
|
|
|
We consider adding new system packages as long as they are indeed used.
|
|
Regarding ``pycups``, you won't be able to configure a printer in the local network of your Odoo.sh server.

The online editor is loading indefinitely
|
|
-----------------------------------------
|
|
|
|
If you can't access the online editor (either a white page, or a frozen loading screen),
|
|
you can restart it by opening a shell on the affected branch and running these two commands:
|
|
|
|
- rm ~/.jupyter
|
|
- pkill -9 jupyter
