Prefect 1.0 If have a "flow of flows", which calls

wait_for_flow_run

several times. I want this parent flow's success to depend on the success of all child flows. I've tried setting

upstream_tasks

to the result of

wait_for_flow_run

, but I realize that that's a

FlowRunView

object, not a

Task

. From the child flow, I can

get_tasks

, and set

upstream_tasks

to that. But I have some tasks I allow to fail in the child flows (they are not reference tasks of the child flow.) What I'd really like to do is to be able to reference

<child_flow>.state

, and set the parent flow's reference tasks to be expecting a

<Success: "All reference tasks succeeded.">

Is there a built-in way of going about this, instead of just manually inspecting the child flow results, and raising the appropriate SIGNAL ?

Hi @Anders Segerberg I believe you can use the

raise_final_state

in the

wait_for_flow_run

to accomplish this. https://docs-v1.prefect.io/api/latest/tasks/prefect.html#wait-for-flow-run Here's a great example.

thank you
