How can I wait for a server side function call?

Anvil Q&A
#1

I’m using @anvil.server.callable to call a server-side function.

I’d like to do X while the function is being called. e.g. Disabling all components until the spinner stops spinning and a value is returned/changed/updated (this value can be the same).

Is there a "while waiting for the server call" kind of function?

Thanks in advance!

Yep, you can use a context manager (“with” statement).

I’m on my phone, but search the forum for “notification with statement” or “wait for notification” or something to that effect.

Neat. It’s actually in the docs:

https://anvil.works/docs/client/python/alerts-and-notifications#notifications

See the parts with with.

As long as “do X” is “display a Notification”, this should work.

If “do X” is something else, then you might consider a Background Task.

Good point. I see that the OP mentioned displaying a message and “disabling user input…etc” which is why I gave that particular suggestion.
