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

```auto
@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)`

Please see the docs on how to use the new forms

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 :)')

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

Basically, you’d need to implement `rasa_sdk` in Node.js. I’m sorry, I don’t have any links for this

I’m implementing formAction in nodeJS. but fails while deactivating a form. any idea about form in node js or how to deactivate form using nodejs. I guess in formAction using rasa-SDK we need to give null in story. I tried same but it doesn’t work. and when a form is excuted it gives the same responce 10times with warning “circuit break tripped. stopped predicting more actions for sender default”

Hi @rohitnairtech do you know about implementation of RASA voice bot? I am facing issue there. As everything is executing well but might servers not getting connected.
