Question

How to pass context from main workflow to inner workflow ?

[dosubot]

To pass context from the main workflow to an inner workflow, you can use the Context object available in the workflow steps. This object helps maintain state across different steps and workflows. Here's a basic example:

In the MainWorkflow, you can pass the query from the StartEvent to the ReflectionFlow by calling reflection_workflow.run(query=ev.query) within the start method. This allows the inner workflow (ReflectionFlow) to receive and process the query:

class MainWorkflow(Workflow):
    @step
    async def start(
        self, ctx: Context, ev: StartEvent, reflection_workflow: Workflow
    ) -> Step2Event:
        print("Need to run reflection")
        res = await reflection_workflow.run(query=ev.query)

        return Step2Event(query=res)

Additionally, the Context object can be used to store and retrieve data across steps, which simplifies the workflow and improves maintainability. You can also serialize and deserialize the context for long-term state management using serializers like JsonSerializer or JsonPickleSerializer ^[1][2].

The ctx is specific to a single workflow -- you probably dont want to do this, unpredictable things will happen

Take what you need from the outter ctx and pass it to the input of the inner
