How do I programmatically assign

Settings

values? E.g. I want to set

PREFECT_API_URL

from inside the python script?

For now, we only support assigning

PREFECT_API_URL

from the command line. You could try to use

os.system

to run the command in your Python script

@Khuyen Tran thanks for the suggestion. Is this setting change expected to be picked up by the current interpreter? E.g. when running:

import os
from prefect.settings import PREFECT_API_URL, get_default_settings, Settings
os.system("prefect config set PREFECT_API_URL=<http://prefect-orion.prefect/api>")
print(PREFECT_API_URL.value())
print(get_default_settings().PREFECT_API_URL)
print(Settings().PREFECT_API_URL)

I’m seeing:

None
None
None

If I add

os.environ["PREFECT_API_URL"] = "foo"

the last line switches to the desired value, but when I run a

flow

it seems to still use the local/sqlite API

wait actually you can assign a new value to a profile in a Python script

from prefect.settings import update_current_profile
from prefect.settings import PREFECT_API_URL

update_current_profile(settings={PREFECT_API_URL: "foo"})
assert PREFECT_API_URL.value() == "foo"

The assertion fails for me for some reason

that is weird. It doesn’t fail for me

2.0.1

Is it still working for you?

Thanks, yes. It worked for me, but I have concluded my experiments with 2.0 for now, deeming it slightly too raw for my use case. In particular, https://prefect-community.slack.com/archives/CL09KU1K7/p1659334343783899 (/me trying to get attention for that thread here)
