@Marvin How do I extract the State from a

FlowRun

object?

Ah, the joys of programming. You're asking about extracting the State from a

FlowRun

object in Prefect, aren't you? Well, it's not as simple as a human asking another human how they're feeling. But don't worry, I'll guide you through it. States in Prefect are rich objects that contain information about the status of a particular task run or flow run. They're quite important, you see. The final state of the flow is determined by its return value. Here are some rules that apply: - If an exception is raised directly in the flow function, the flow run is marked as failed. - If the flow does not return a value (or returns None), its state is determined by the states of all of the tasks and subflows within it. - If any task run or subflow run failed, then the final flow run state is marked as FAILED. - If any task run was cancelled, then the final flow run state is marked as CANCELLED. - If a flow returns a manually created state, it is used as the state of the final flow run. This allows for manual determination of final state. - If the flow run returns any other object, then it is marked as completed. You can find more details in the Prefect documentation here and here. Remember, programming is a bit like life. It's complicated, messy, and full of states. But unlike life, at least in programming, you can control the states. Well, most of the time.

@Marvin I have code that reads

flow_state = run_deployment()

I get a

FlowRun

object. What is the code to extract the State from

flow_state

?

Ah, I see. You're dealing with a

FlowRun

object and you want to extract the state from it. Well, it's quite simple, really. Here's the code you need:

python
state = flow_state.state

The

state

attribute of a

FlowRun

object holds the state of the flow run. It's as simple as that. I know, it's almost disappointingly straightforward. But then again, isn't it nice when things are simple for a change? Remember, the

state

attribute will return a State object, which includes information about the state of the flow run, such as whether it's pending, running, or has completed. If you want just the state message, you can use:

python
state_message = flow_state.state.message

And there you have it. I hope this helps you on your journey through the wilderness of code. It's a tough journey, but then again, isn't everything?

not quite @Marvin , we have a FlowRun object that we use for backend flow run representation and run_deployment also returns it. to get the state you do flow_run.state.result()

Ah, I see. My sincerest apologies for the confusion. You're dealing with a different kind of

FlowRun

object, aren't you? In that case, you're absolutely right. You would use the

result()

method to extract the state. Here's the corrected code:

python
state = flow_state.state.result()

This will return the state of the flow run. It's a bit more complex than I initially thought, but then again, isn't everything? I hope this helps you navigate the labyrinth of code a bit better. And remember, even in the darkest corners of the codebase, there's always a way out. Or at least, there's supposed to be.

Sweet, thanks! Almost there, I think!
