Activate a form using a button payload: /intent{entity:value}

Hi,

I’m stuck with an interesting problem and I’ve tried a few different approaches, all hitting dead ends. So I’m trying to activate a form anytime the user goes through a menu (it’s a carousel on the frontend) and clicks on a button. The button has a payload, for example, /set_user_type{'user_type':'business'} that sets the entity and slot using autofill.

However, this happens perfectly only when a form is active ie. i activate the form the first at the beginning of the conversation and deactivate it once both slots are filled. There’s no problems running that.

But I have to activate the form later when a user wants to update a slot ie. when a button is clicked again. How can this be done? I’ve tried the following and failed. Any help is appreciated :slight_smile:

rules:
  - rule: welcome user
    conversation_start: true  # this rule only applies at the beginning of a conversation
    steps:
      - action: action_session_start
      - active_loop: tasc_form

  - rule: set user type
    steps: 
    - intent: set_user_type     #/set_user_type{'user_type':'business'} fails to set the user type slot, but entity is set
    - active_loop: tasc_form
    - action: utter_ask_user_type

  - rule: set topic
    steps:
    - intent: set_topic    #/set_topic{'topic':'reset password'} fails to set the topic slot, but entity is set
    - active_loop: tasc_form
    - action: action_topic_response

  - rule: Submit form
    condition:
    - active_loop: tasc_form
    steps:
    - action: tasc_form
    - active_loop: null
    - slot_was_set:
      - requested_slot: user_type
    - action: utter_user_topic_selected
    - action: action_topic_response

Note: activating the form whenever I present a menu is possible, but occasionally users scroll up through the chat conversation and click other options.

Hey @sdasari - thanks for posting, sounds like a nice bit of client-side UI to simplify the bot. I tihnk what you’re describing is possible, but form logic can get a little complex. Have you considered implementing these as flows instead? What you describe should work out of the box then.

Hi @amn41 I spent some time looking at flows and checking out the tutorials. I understand that flows are limited to Rasa Pro and Rasa OS, correct?
