Extracting slot method - advice on how to use

Hi,

I have a form which at the end, asks if the user wants to enter freeform comments. If they say “Yes” I dynamically add a slot.

However, validation only occurs if it has been extracted. I have therefore created an extract_<slot_name> method. Using the example from the RASA website it simply gets the user input i.e.

text_of_last_user_message = tracker.latest_message.get("text")

However, this picks up the “yes” from the previous user’s input to agreeing to enter comments and skips my slot (as it’s just a freeform text field).

Can you advise on the best way to get the input only if they are being asked the question from the slot you’re in?

Thanks!

In absence of a response, I changed my extract method to only pick up the text for the slot I was on i.e. survey_comments:

if tracker.get_slot('requested_slot') == 'survey_comments':
    text_of_last_user_message = tracker.latest_message.get('text')

This works for me. Not sure if it’s the best way but I am not sure how the sample code works when adding a slot to pre-existing form slots without picking up the current field’s text first.
