Hello! There is a posibility create new flow run from code:

client.create_flow_run(

flow_id="d7bfb996-b8fe-4055-8d43-2c9f82a1e3c7",

flow_run_name="docs example hello-world"

)

But when run triggered by prefect the names are random. Or you can set manualy from UI flow_run_name. My tipical prefect script looks like :

@task

def task1():

pass

@task

def task1():

pass

with Flow() as flow:

task1()

task2()

...

client.register(flow, project_name='project')

Is there way set run_flow_name by default in code? For example:

name = f"name_{datetime.datetime.utc()}"

I was just typing this up for our FAQ. You can use a state handler with the RenameFlowRun task

from prefect import Flow, task
from prefect.tasks.prefect import RenameFlowRun

def rename_handler(obj, new_state, old_state):
    if new_state.is_running():
        RenameFlowRun().run(flow_run_name="new_name")
    return

@task
def first_task():
    return 1

with Flow("test-flow", state_handlers=[rename_handler]) as flow:
    first_task()

@Kevin Kho thanks!
