Hi, I tried to search but don’t seems find related answer. I want to change the auto-generated container like names “happy-jelly” stuff. But I don’t want to overcomplicate things like to

create_flow_run

in code. What’s the simpliest thing to change by giving the flow run a customized run-id? Assume I only need to trigger the flow run using schedules or UI.

Hey @Tony Yun, the simplest way would be to use the

RenameFlowRun

task inside your flow code. Docs

does it require to add a task for renaming a flow run id?..

That’s more automated, but through the UI you can hover over the flow run name and a pencil will appear and you can click it.

the UI change is for one-time only looks like.

create_flow_run

takes in a

run_name

argument if you are using the

Client

using Client is also one time only triggers I thought?

Sorry I am confused. If you want it recurring and always changing for scheduled runs, then

RenameFlowRun

in the flow would be the easiest approach. It can’t be set as the flow is created, unless a one time thing with

create_flow_run

thanks! btw, the example in the API doc is very outdated. After correcting the errors, I can’t seem do it right still:

RenameFlowRun("hello-flow-1", flow_run_name='test-1')

with Flow(
    "hello-flow", 
    schedule
) as flow:
    # download_report()
    load_report(upstream_tasks=[download_report])

The id is a uuid and the name is the string.

RenameFlowRun

has to be inside the

Flow

You don’t need to supply the id. Just do

RenameFlowRun()(flow_run_name="new_name")

inside the Flow.

hmm, it seems it’s not a good practice. I’ll give it up using it this way then. Thank you for the help!

This can occur when `Task` classes, including `Parameters`, are instantiated inside a `with flow:` block but not added to the flow either explicitly or as the input to another task. For more information, see <https://docs.prefect.io/core/advanced_tutorials/task-guide.html#adding-tasks-to-flows>.

You need it under the flow block:

with Flow(
    "hello-flow", 
    schedule
) as flow:
    RenameFlowRun()(flow_run_name='test-1')
    load_report(upstream_tasks=[download_report])
