@akelad need your help here. Thanks Slots gets extracted but does not get validated using validate_<slot_name> function. Following current guidelines here Forms Logs 2020-10-14 17:06:20 DEBUG rasa.core.processor - Logged UserUtterance - tracker now has 297 events. 2020-10-14 17:06:20 DEBUG rasa.core.policies.rule_policy - Predicted loop ‘order_form’. 2020-10-14 17:06:20 DEBUG rasa.core.policies.ensemble - Predicted next action using policy_0_RulePolicy 2020-10-14 17:06:20 DEBUG rasa.core.processor - Predicted next action ‘order_form’ with confidence 1.00. 2020-10-14 17:06:20 DEBUG rasa.core.actions.forms - Validating user input ‘UserUttered(text: lays, intent: {‘id’: 3152659454284902011, ‘name’: ‘inform’, ‘confidence’: 0.999991774559021}, entities: [{‘entity’: ‘snack’, ‘start’: 0, ‘end’: 4, ‘confidence_entity’: 0.8661425709724426, ‘value’: ‘lays’, ‘extractor’: ‘DIETClassifier’}])’. 2020-10-14 17:06:20 DEBUG rasa.core.actions.forms - Trying to extract requested slot ‘snack’ … 2020-10-14 17:06:20 DEBUG rasa.core.actions.forms - Got mapping ‘{‘type’: ‘from_entity’, ‘entity’: ‘snack’}’ 2020-10-14 17:06:20 DEBUG rasa.core.actions.forms - Successfully extracted ‘lays’ for requested slot ‘snack’ 2020-10-14 17:06:20 DEBUG rasa.core.actions.forms - Validating extracted slots: {‘snack’: ‘lays’} 2020-10-14 17:06:20 DEBUG rasa.core.actions.action - Calling action endpoint to run action ‘validate_order_form’. 2020-10-14 17:06:20 DEBUG rasa.core.actions.forms - Request next slot ‘size’ and My custom action: from typing import Dict, Text, List from rasa_sdk import Tracker from rasa_sdk.events import EventType from rasa_sdk.executor import CollectingDispatcher from rasa_sdk import Action from rasa_sdk.events import SlotSet from typing import Text, List, Any, Dict from rasa_sdk import Tracker, FormValidationAction from rasa_sdk.types import DomainDict from rasa.shared.core.domain import Domain class ActionSwitchFAQ(Action): def name(self) -> Text: return "action_switch_faq" def run( self, dispatcher: CollectingDispatcher, tracker: Tracker, domain: Dict ) -> List[EventType]: return [SlotSet("detailed_faq", not tracker.get_slot("detailed_faq"))] class ValidateOrderForm(FormValidationAction, Action): def name(self) -> Text: """Unique identifier of the form""" return "validate_order_form" def run( self, dispatcher: CollectingDispatcher, tracker: Tracker, domain: Dict ) -> List[EventType]: # dispatcher.utter_message("validate_some_slot") # return [SlotSet("some_slot", "sdk")] return [] def validate_snack( self, slot_value: Any, dispatcher: CollectingDispatcher, tracker: Tracker, domain: DomainDict, ) -> Dict[Text, Any]: """Validate cuisine value.""" print("Slot Value=", slot_value) if slot_value == "fries": print("validation succeeded") return {"…

ahhh @noman it’s because you overwrote the run() function, which now doesn’t do anything. If you remove it I believe it should work

Could you share the logs of your action server? It seems like it does call your action server to validate the slots

Logs before filling the snack slot 2020-10-14 17:32:58 INFO rasa_sdk.endpoint - Starting action endpoint server... 2020-10-14 17:32:58 INFO rasa_sdk.executor - Registered function for 'action_switch_faq'. 2020-10-14 17:32:58 INFO rasa_sdk.executor - Registered function for 'validate_order_form'. 2020-10-14 17:32:58 INFO rasa_sdk.endpoint - Action endpoint is up and running on http://localhost:5055 validate_order_form Run Called Logs after i enter the value for snack slot 2020-10-14 17:32:58 INFO rasa_sdk.endpoint - Starting action endpoint server... 2020-10-14 17:32:58 INFO rasa_sdk.executor - Registered function for 'action_switch_faq'. 2020-10-14 17:32:58 INFO rasa_sdk.executor - Registered function for 'validate_order_form'. 2020-10-14 17:32:58 INFO rasa_sdk.endpoint - Action endpoint is up and running on http://localhost:5055 validate_order_form Run Called validate_order_form Run Called

And you should only need to subclass the FormValidationAction so that it’s class ValidateOrderForm(FormValidationAction) The default implementation of the run method is listed here

ahan ok but to add custom slot mappings and require extra slots we need to override run function as stated here Forms . Then in this case what will we do?

Then you subclass a normal Action, and define the validation logic there. You can find an example in Sara, our demo bot, here - keeping in mind that the method has been renamed to tracker.slots_to_validate. The example is still in process of being updated

In helping you out with this I realise that that implementation isn’t ideal, and the docs are also a little bit confusing! Will talk to our team on how to address this :slight_smile:

ok Thanks. @akelad can i keep using FormAction from rasa_sdk with rasa==2.0?

Yeah it would be great :slight_smile:

hm, i think it’s still gonna work for now, but we will deprecate it eventually. So it’s better to migrate eventually. Are there any particular parts you’re struggling with?

Hmm ok. Right now i was facing the problem in validation, if i face any while exploring rasa==2.0, will ping you. Thanks for the help.

Rasa 2.0 Forms does not validate extracted slots and asks the next slot
