Content of actions file:

class UniversityForm(FormAction):


   def name(self):
       # type: () -> Text
       """Unique identifier of the form"""

       return "action_get_information"

   @staticmethod
   def required_slots(tracker):
       # type: () -> List[Text]
       """A list of required slots that the form has to fill"""

       return ["address"]

   def submit(self, dispatcher, tracker, domain):
       # type: (CollectingDispatcher, Tracker, Dict[Text, Any]) -> List[Dict]
       """Define what the form has to do
           after all required slots are filled"""

       # utter submit template
       dispatcher.utter_template('utter_submit', tracker)
       return []

Can anyone help me to figure out why form action is not asking for required slots?

you need to add the form to your domain file, and also add a story that actually activates the form. Please refer to the docs here: https://rasa.com/docs/core/slotfilling/

@akelad i have made changes by following example of formbot in github.

In my case, form action is executed, but it directly execute utter_submit rather than filling address slot

@rameshjesswani you're using Rasa Core 0.11.7, documentation is for newer version 0.12.X. Library update should do the trick 😄

[rameshjes]

@marostr thanks . I updated it, but now i am getting this error:

"You have defined a form action, but haven't added the "
rasa_core.domain.InvalidDomain: You have defined a form action, but haven't added the FormPolicy to your policy ensemble.

[marostr]

@rameshjesswani sure! Have you tried adding - name: FormPolicy to your policies.yml?

[rameshjes]

sorry, i dont know where to create policies.yml , could you please elaborate more or provide relevant sources? I am following formbot example in github, i cannot see any policies.yml

[rameshjes]

I created policy.yml as:

policies:
  - name: KerasPolicy
    epochs: 50
    max_history: 6
  - name: MemoizationPolicy
    max_history: 6
  - name: FallbackPolicy
    nlu_threshold: 0.8
    core_threshold: 0.3
  - name: FormPolicy

It worked. Thanks :)

I created policy.yml as:

policies:
  - name: KerasPolicy
    epochs: 50
    max_history: 6
  - name: MemoizationPolicy
    max_history: 6
  - name: FallbackPolicy
    nlu_threshold: 0.8
    core_threshold: 0.3
  - name: FormPolicy

It worked. Thanks :)

In the latest version v1.1.4 , this needs to be added to config.yml
