Hi @Tobias_Wochinger! Thank you for the compliment! I tried adding validation to the sugar and cream inputs and it is still acting the same way. However, I do like having an int validation in place.
Here is my form:
class CoffeeForm(FormAction):
"""Form action to capture contact details"""
def name(self):
# type: () -> Text
"""Unique identifier of the form"""
return "coffee_form"
@staticmethod
def required_slots(tracker):
# type: () -> List[Text]
"""A list of required slots that the form has to fill"""
return ["customer_name", "blend", "num_sugar", "num_cream"]
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"""
dispatcher.utter_template('utter_coffee_confirm_order', tracker)
return []
def slot_mappings(self):
# type: () -> Dict[Text: Union[Dict, List[Dict]]]
"""A dictionary to map required slots to
- an extracted entity
- intent: value pairs
- a whole message
or a list of them, where a first match will be picked"""
return {"customer_name": [self.from_entity(entity="PERSON",
intent="self_intro"),
self.from_text()],
"blend": [self.from_entity(entity="blend"),
self.from_text()],
"num_sugar": [self.from_entity(entity="num_sugar"),
self.from_text()],
"num_cream": [self.from_entity(entity="num_cream"),
self.from_text()]}
@staticmethod
def is_int(string: Text) -> bool:
"""Check if a string is an integer"""
try:
int(string)
return True
except ValueError:
return False
def validate_num_sugar(
self,
value: Text,
dispatcher: CollectingDispatcher,
tracker: Tracker,
domain: Dict[Text, Any],
) -> Dict[Text, Any]:
"""Validate num_sugar value."""
if self.is_int(value) and int(value) > 0:
return {"num_sugar": value}
else:
dispatcher.utter_template("utter_wrong_num_input", tracker)
# validation failed, set slot to None
return {"num_sugar": None}
def validate_num_cream(
self,
value: Text,
dispatcher: CollectingDispatcher,
tracker: Tracker,
domain: Dict[Text, Any],
) -> Dict[Text, Any]:
"""Validate num_cream value."""
if self.is_int(value) and int(value) > 0:
return {"num_cream": value}
else:
dispatcher.utter_template("utter_wrong_num_input", tracker)
# validation failed, set slot to None
return {"num_cream": None}
As you could see on Rasa X, both sugar and cream slots are populated, yet it came back indicating one of the slots is “none”.
