okay so I am trying to translate a prefect core flow to prefect cloud flow. I want to be able to make changes locally and have it update my cloud flow. Is this possible?

You will need to re-register for the most part for the changes to take effect

And then how do I trigger a cloud run from local after registration?

With Python,

Client.create_flow_run(...)

With CLI

prefect run --project project_name --name flow_name

will trigger a run on Cloud

Ah! Success.

Not super understanding, but that seems like it can be solved by a

if ___name___ == ___main___

to register right?

In my file there is this

registered_flow_id = flow.register(project_name="Development")
    client.create_flow_run(flow_id=registered_flow_id)

Ah ok you can do

flow.register(build=False)

by default I guess?

The latter!

Task docs are here

That's awesome

That is also an option, but

create_flow_run

is the newer task

And there's not a secret way to have the flow detect changes right? lol

You can compare the

flow.serialized_hash()

. So you can try running this twice:

prefect register -p some_flow.py

and on the second one, it will not register because no changes were made. This is because the CLI uses

flow.serialized_hash()

as an idempotency key. So if you try to register with the same idempotency key, it will just return the id of the old run

So it is not able to do that in-code, just via the cli?

Yeah that code path is only in the CLI so you’d need to replicate it or come up with your own identifier around the serialized hash
