hi all, I am using Rasa 2.8.15. I have a Form and using action.py to validate slots. For one of them, if intent == 'affirm', I want to trigger a FollowupAction() event. However because it is a slot validation method the returned object needs to be defined as a dictionary… how can I do it? def validate_formslot(self, slot_value: Text, dispatcher: CollectingDispatcher, tracker: Tracker, domain: DomainDict) -> Dict[Text, Any]: if tracker.latest_message['intent'].get('name') == 'affirm': return {"formslot": slot_value, [FollowupAction(action_name)]} This does not work…

[image] userRasa03: I think I have not been very clear, apologies. No worries :slight_smile: [image] userRasa03: Your suggestion above will make the bot say 'Write your action here'in case the "followup" slot has a value of 'action_test'… but no custom action () gets executed if I understand correctly? The bot would then ask the user to fill the next domain_slot , instead of reacting to user response to the Action, right? All correct! [image] userRasa03: I dont understand how to execute the action from the required_slots()? What’s not clear about it? You write your action in the if block instead of separately. For example: def required_slots(self, domain_slots, dispatcher, tracker, domain): if tracker.slots.get('followup') == 'action_get_weather': location = tracker.get_slot('location') weather_info = getWeather(location) temperature = weather_info['temperature'] dispatcher.utter_message(f'The temperature is {temperature} degrees in {location}.'). return domain_slots Just make sure to set the slot to None again in the next validation method :slight_smile: Otherwise this will be executed every time. Or, alternatively, you can do something like this (next_slot_name is the slot that will be filled next, and you’re checking it has not been filled): if tracker.slots.get('followup') == followup_action_name and tracker.slots.get(next_slot_name) is None:

As you said, you cannot do it here. What I suggest to do is setting a special slot: def validate_formslot(self, slot_value, dispatcher, tracker, domain): if tracker.latest_message['intent'].get('name') == 'affirm': return {"formslot": slot_value, "followup": action_name} Then, in the required_slots method, you return an empty list if the followup slot is set: def required_slots(self, domain_slots, dispatcher, tracker, domain): if tracker.slots.get("followup") is not None: return [] return domain_slots Then, you write stories and a rule in which the followup slot is set while the form is active. And when that’s the case, the action gets executed :slight_smile: - story: Execute followup from form steps: - intent: whatever - action: form_whatever - active_loop: form_whatever - slot_was_set: - followup: action_followup - slot_was_set: - requested_slot: null - action: action_deactivate_loop - active_loop: null - action: action_followup - rule: Execute followup from form condition: - active_loop: form_whatever steps: - action: form_whatever - active_loop: null - slot_was_set: - followup: action_followup - slot_was_set: - requested_slot: null - action: action_followup

thanks for suggesting @ChrisRahme . I dont understand how you can set "followup": action_name if the action_name has not been defined in the validation function? I also dont understand how the action gets executed if the return [ ] is empty? With your stories an action gets executed and I get out of the form, which I dont want to happen. I would like an action to be executed if an intent is recognized, and then keep filling the Form slots… let me know thanks

[image] userRasa03: I dont understand how you can set "followup": action_name if the action_name has not been defined in the validation function? Define it :slight_smile: You did not define it in your example, so I did not define it in mine. [image] userRasa03: I also dont understand how the action gets executed if the return [ ] is empty? You return [] to end the form, and then the action will be executed from stories. [image] userRasa03: With your stories an action gets executed and I get out of the form, which I dont want to happen. I would like an action to be executed if an intent is recognized, and then keep filling the Form slots You should have mentioned this from the start. Why not execute the action from the required_slots() method then? def required_slots(self, domain_slots, dispatcher, tracker, domain): if tracker.slots.get("followup") == 'action_test': dispatcher.utter_message('Write your action here') return domain_slots

thanks for suggesting @ChrisRahme very helpful. I think I have not been very clear, apologies. Your suggestion above will make the bot say 'Write your action here'in case the "followup" slot has a value of 'action_test'… but no custom action () gets executed if I understand correctly? The bot would then ask the user to fill the next domain_slot, instead of reacting to user response to the Action, right? I dont understand how to execute the action from the required_slots()?

I will try to see if it works, thanks. My only concern is: the 'action_get_weather' gets triggered (meaning, bot says 'The temperature is {temperature} degrees in {location}.', and the user is not able to reply and have a different conversation flow, because we are including just the utter_message but the bot does not wait for user reply, it will prompt with the utter_next_slot (i mean the next slot to be filled).

Isn’t that what you want? You said yourself that the form should continue. Anyway, I gave you all the basic possibilities. Try to learn by yourself and mix what I taught you according to your needs. For example, you could execute that “action” in the required_slots method and return [], then go back to the form using a story… There are so many possibilities, I will not and cannot showcase them all here - especially that you did not specify your use case, so there are lots of ways to interpret what you want to do. Anyway, I gave you the building blocks and logic, you should be able to learn and modify this info according to your needs. Good luck :slight_smile:

will try use these building blocks yes, thansks. I think based on what I described and your advice the way to go is to use different stories.

[image] ChrisRahme: filled can you answer for this question as well [image] Trigger Action from form validation Rasa Open Source I have a form during the validation of a slot in the form i want to move to an action to trigger an new form . how to achieve the same .
