Activate Form in Calling FormAction in CustomAction

Rasa Open Source
1

Hi i want to activate form through custom action, anyone knows how to do that?

for example:

        req_details = FeedbackForm()
        req_details.run(dispatcher, tracker, domain)

FeedbackForm is inheritance from FormAction, its work but the form is not opening and closing, i want to set activate before the feedbackform run

The reason i want to use this because i’m using mapping policy default fallback for this actions

Thankyou, Rino Alfian

In order for the form to open and close, you need to return the events returned by the run method of the form

3

any docs or example code to return the events by the run method of the form? i still didn’t get it

4

each run method returns the list of events (Actions) that are passed to rasa core, that’s how rasa core knows that a form was activated. Therefore your custom action should return these list of events

class ActionDefaultFallback(Action):
    def name(self):
        return "action_default_fallback"

    def run(self, dispatcher, tracker, domain):
        # print(tracker.current_state())
        print("******************default************************")
        wrong_counter = tracker.get_slot('fallback_counter')
        if wrong_counter == None:
            wrong_counter = 0
            wrong_counter += 1
            req_details = FeedbackForm()
            form_name = req_details.name()
            dispatcher.utter_template('utter_default_fallback',tracker)
            req_details.deactivate()
            dispatcher.utter_template("utter_i've_sent_details", tracker)
            dispatcher.utter_template("utter_thankyou_for_feedback", tracker)
            return [Form(form_name)]

thats the sample code, now the condition is the bot reply only the default fallback utterances, it won’t return the form, if i want the form to showup there, i have to type something first, its like form stucking if i didnt type something after utter_Default_fallback comes up

I don’t understand what do you mean, why do you need a form inside fallback action? fallback action is not designed for that

I think this is what you’re looking for: https://innovationyourself.com/form-action-with-your-rasa-chat-bot/

Instead of creating class ActionFormInfo(FormAction) You would create: class ActionDefaultFallback(FormAction)

And in that action you can define the details of your FeedbackForm
