Hi, I'm wondering if there's a way to attach a key to a

context

value on a per run basis?

Hey @Philip MacMenamin I'm having some trouble conceptualizing what you're trying to do here haha😅, Do you mind describing what you're trying to accomplish here?

Hi Mason - sorry to be unclear, something along the lines of:

@task

def my_task_2(i: int) -> Tuple[int, int]:

# read something from context

fp = context.fp

do_thing(fp)

return (1, 2)

@task

def my_task() -> Tuple[int, int]:

# assign something to context

prefect.context.fp="/tmp/blah"

return (1, 2)

with Flow("flow_run_name") as f:

a, b = my_task()

my_task_2(a)

So something like this would probably work, the config is technically just a dictionary that gets reference when the flow is run so this should only create a key value pair in the dictionary on a per run basis that you can reference in other flows, I'm not 100% certain this would work well in a flow context. That being said it might make more sense to create a separate task to generate the appropriate parameter based on the current flow run rather than setting it in the config context

from prefect import Flow, task, config

@task
def foo(x: int):
    config["test_key"] = "somval"


@task
def bar():
    print(config["test_key"])

with Flow('test-config') as flow:
    foo()
    bar()

flow.run()

Ah,

config

. OK, yup, this does what I want. Thank you.

No problem 😄
