Is there a way to use optional filed or to set one of the multiple fields as required I am looking for something like this @staticmethod def required_fields(): # how can i access the slots in this function duration = tracker.get_slot("duration") return_date = calculate_return_date(departure_date, duration) SlotSet("retrun_date", retrun_date) return [ EntityFormField("to", "to"), EntityFormField("from", "from"), EntityFormField("departure_date", "departure_date"), EntityFormField("return_date", "return_date") ] what is the right way to achieve this?

We recently released rasa_core and rasa_core_sdk 0.12.1 with the new forms, you can do it there by subclassing required_slots(tracker) RasaHQ/rasa_core_sdk/blob/47106d959767148d15b328a3a38a95cd697e0616/rasa_core_sdk/forms.py#L34 class FormAction(Action): def name(self): # type: () -> Text """Unique identifier of the form""" raise NotImplementedError("A form must implement a name") @staticmethod def required_slots(tracker): # type: (Tracker) -> List[Text] """A list of required slots that the form has to fill Use `tracker` to request different list of slots depending on the state of the dialogue """ raise NotImplementedError("A form must implement required slots " "that it has to fill") Please see the docs on how to use the new forms

[image] pragya-96: EntityFormField it looks like you use old FormAction what version of rasa_core and rasa_core_sdk do you use? It is impossible to read not indented code!

Hey @Ghostvv thanks for listening. I am using rasa core version 0.12.2. here is my actions.py file from rasa_core.actions import Action from rasa_core_sdk.events import SlotSet class ActionOrderPizza(FormAction): RANDOMIZE = False @staticmethod def required_fields(): return [ EntityFormField("size", "size"), EntityFormField("toppings", "toppings") ] def name(self): return 'action_order_pizza' def submit(self,dispatcher,tracker,domain): size = tracker.get_slot("size"), toppings = tracker.get_slot("toppings") dispatcher.utter_message("your pizza size of") dispatcher.utter_message(size) dispatcher.utter_message("and with toppings") dispatcher.utter_message(toppings) dispatcher.utter_message('Ordering Pizza is completed! It should be with you soon :)')

what version of rasa_core_sdk do you use? EntityFormField is not supported anymore

i am using rasa_core_sdk verion 0.12.1. if not EntityFormField then what is to be used?

Please check the docs: Slot Filling

hey @Ghostvv how can I use formAction in Node.js instede of python

You need to implement all the methods in FormAction class in Node.js, make sure that you return the same jsons

Even if I skip the rasa-sdk for my project? Do you have any resource link for formAction In node @Ghostvv
