Is there currently a way of overriding a task name when calling it in Prefect 2? The following (which is what the documentation recommends, unless I'm reading it wrong) appears to have no effect: my_task_function(name="Custom Task Name") The task run name for the above task ends up being "my_task_function-6971d82e-1"

The name part goes in the task decorator, eg

@task(name="Custom Task Name")

def my_task_function():

That's one way of doing it, but then I can't override it each time I execute the task, which is what I'm trying to accomplish. Unless you can override task decorators at runtime?

oops, in which case:

my_task_function.with_options(name="Custom Task Name")

, worked for me

Awesome, that works. Thanks! 🤩

not sure why you can’t see the change in the UI.

@task(name="Custom Task Name")

should change your task name into

Custom Task Name-id

I think I wasn't explaining my issue properly: I need to run the same task, multiple times, with different names. So I don't think the decorator override will do! with_options worked, even though it's a bit clumsy to use. So I'm all good now.

Is there a way to template the task name based on the input like in v1.0 ? (especially for mapped tasks) https://docs-v1.prefect.io/core/concepts/templating.html

We currently don’t support it, but here is the work around

thank you. this will work for me 🙂

Feel free to open a GitHub feature request for dynamic templating of task run names — I do not believe there are workaround for mapping yet.

@Timo Can you open a GitHub issue on Prefect repo so we can keep track of the issue?
