Hi Is there a way to `pass` on a if else branch

Question

Jeremiah · Answer

Hi < itay livni> could you give a little more detail on what you want your workflow to do when that `pass` happens You can absolutely make a task that does nothing but `pass` in which case it will return a `Success` state to any downstream tasks containing no result

itay livni · Answer

something like this

Jeremiah · Answer

I think I see you ll need to change how you write code in Prefect The code you ve written is as if your task results are known for example `x lst value count max ` In Prefect task results are not known until the flow is run and consequently all operations including things like `some str is short ` must happen inside the `run ` method of a `Task` object

Jeremiah · Answer

So with `ifelse` you re saying if the first task evaluates `True` run the second task otherwise run the third task ``` ifelse conditional task true task false task ```

Jeremiah · Answer

Then you can follow that with new task dependencies

Jeremiah · Answer

``` another task on true branch set upstream true task another task on false branch set upstream false task ```

Jeremiah · Answer

And the ifelse will skip all the tasks that don t get run

itay livni · Answer

so the test statement i e `termsense stat response min num term senses gt 1` has to be a task Here is an implementation of what I am trying to do in an aws state machine

itay livni · Answer

sorry wrong one

Jeremiah · Answer

Yes every operation in Prefect must be a `Task` In this case you could use an `ifelse` to run `task1` if the condition is true or `task2` if the condition is false You could also call `task2 set upstream task1 ` This way task 2 will always run but task 1 will only run if the condition is met
