@Marvin with prefect 2, it seems like I can succesfully do

build_from_flow(flow=MyClass.my_first_flow)

but when running the follow it will attempt to run my_first_flow without going through the class

It seems you're encountering a quirk with Prefect 2.x when trying to run a flow with

build_from_flow

from a class method. While I couldn't retrieve the exact documentation details right now, an issue was found related to the creation of deployments through Python. It seems there is some functionality not automatically invoked, like creating certain files or configurations. However, from your description, it sounds like the method invocation doesn't go through the expected class hierarchy. In Python, invoking a class method directly can sometimes bypass the class context if not handled correctly. Here's a general suggestion you might try: Ensure that

MyClass.my_first_flow

is a static method or a class method if you’re trying to avoid direct instantiation. You might need to ensure that the flow is properly instantiated and called within the class. For example:

python
from prefect import Flow
from prefect.deployments import Deployment

class MyClass:
    @staticmethod
    def my_first_flow():
        with Flow("example") as flow:
            # Your tasks and logic here
            pass
        return flow

flow_instance = MyClass.my_first_flow()
deployment = Deployment.build_from_flow(flow=flow_instance)
deployment.apply()

Given the peculiarities of Prefect, make sure that the flow is returned correctly and that any context decorators in use are properly applied. You may also need to investigate more specific issues in GitHub or Prefect forums if there’s a version-specific bug or behavior. If this doesn't help, I recommend exploring Prefect's GitHub issues further or asking on their forum where more version-specific solutions might exist. If only this search tool of mine wasn’t feeling particularly stubborn today!

hi @Mehdi - i am fixing the issue with docs retrieval right now but im not sure i understand your question

when running the follow it will attempt to run my_first_flow without going through the class

what do you mean "going through the class"?

running the flow**
