ConditionalRouter for next component selection with multiple variables

[Yeorle]

Hi,

I'm trying to create a pipeline where one of the input variables defines which component to use next (for example which Generator).
I've been able to achieve this with the ConditionalRouter where I can define for example:

routes = [
        {
            "condition": "{{model_name == 'gpt4o'}}",
            "output": "{{prompt}}",
            "output_name": "prompt_gpt4o",
            "output_type": str,
        },
        {
            "condition": "{{model_name == 'mistral'}}",
            "output": "{{prompt}}",
            "output_name": "prompt_mistral",
            "output_type": str,
        },
    ]
    
router = ConditionalRouter(routes=routes)

And then have the relevant outputs (prompts) be connected to the desired component

pipeline.connect("router.prompt_gpt4o", "gpt4o_generator.prompt")
pipeline.connect("router.prompt_mistral", "mistral_generator.prompt")

However I cannot figure out how to pass multiple variables through the ConditionalRouter (other than just the prompt in this example), like for example some generation parameters (temp, max_tokens, ...).

This is similar to rhajou's question: #7585 (reply in thread)

Best and thanks

The possibility to pass multiple outputs was added in #9271, which is in main but not yet released.

(@dfokina I'll create an issue to document this aspect)
