Question

Garret Cook · Answer

maybe I can put them in context as I go

Kevin Kho · Answer

Hey < Garret Cook> you can t modify the context I think there are a couple of ways to achieve this but could you tell me more about what you re trying to do

Garret Cook · Answer

I wanted to use a flow result handler to send a message

Garret Cook · Answer

But I wanted to add some data to that message

Garret Cook · Answer

Some of the flow results you know like success 41 files transferred

Garret Cook · Answer

that sort of thing just some basic metadata about what happened and how

Garret Cook · Answer

I ve scoured google and the docs tried it half a dozen ways and just can t seem to figure it out

Kevin Kho · Answer

You may have to use FlowRunView <https docs prefect io api latest backend flow run html flowrunview|here> Instantiate it inside the flow handler with `FlowRunView from flow run id prefect context get flow run id ` inside the state handler After that you can use ` FlowRunView get all task runs ` which gives you a list of `TaskRunView` objects Each `TaskRunView` object can be used to get the result using the ` get result ` method This is all new in 0 15 0 so I haven t tried it myself quite yet but I think it should work

interesting ok

Garret Cook · Answer

Is there a better pattern for doing this

Garret Cook · Answer

I just need to let accounting know whether it was pass fail and how many uploads were moved through

Kevin Kho · Answer

Is it just like a mapped task

Garret Cook · Answer

Right

Kevin Kho · Answer

Check <https prefect community slack com archives C014Z8DPDSR p1625870774443500 thread ts=1625099514 314400 amp cid=C014Z8DPDSR|this> You can keep track of the state I guess and then feed that to another task for reporting

Garret Cook · Answer

Gotcha ok Thank you

Garret Cook · Answer

I think I saw you have a talk coming up good luck I hope it goes well

Kevin Kho · Answer

Yep I do next week Thanks

Kevin Kho · Answer

That code snippet is slightly different because he needed task inputs instead of results for his reporting
