Hi
I have a working FormAction in which I fill multiple slots.
Goal:
After all slots are filled, I want to sent / export all slot values into a json file. Or is there a better way to store slot values, then please let me know!
My approach:
I think in order to solve my problem I have to change the function def submit in my FormAction. According to the documentation this function is about “what to do at the end of the form, when all the slots have been filled”.
This might be useful but I didn’t know how to apply it to my case: sent slot values in JSON
Maybe you can help me with this?
Here is my FormAction (which works properly):
actions.py
class AuthenticateFormShort(FormAction):
"""Example of a custom form action"""
def name(self):
# type: () -> Text
"""Unique identifier of the form"""
return "authenticate_form_short"
@staticmethod
def required_slots(tracker):
# type: () -> List[Text]
"""A list of required slots that the form has to fill"""
return ["name"] # Every time the form action gets called, it will ask the user for the next slot in required_slots which is not already set. Note the order!!!
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_form_bye', 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 {
"name": [self.from_entity(entity="name", not_intent=["chitchat"])],
}
def validate(self,
dispatcher: CollectingDispatcher,
tracker: Tracker,
domain: Dict[Text, Any]) -> List[Dict]:
"""Validate extracted requested slot
else reject the execution of the form action
"""
# extract other slots that were not requested
# but set by corresponding entity
slot_values = self.extract_other_slots(dispatcher, tracker, domain)
# extract requested slot
slot_to_fill = tracker.get_slot(REQUESTED_SLOT)
if slot_to_fill:
slot_values.update(self.extract_requested_slot(dispatcher,
tracker, domain))
if not slot_values:
# reject form action execution
# if some slot was requested but nothing was extracted
# it will allow other policies to predict another action
raise ActionExecutionRejection(self.name(),
"Failed to validate slot {0} "
"with action {1}"
"".format(slot_to_fill,
self.name()))
# we'll check when validation failed in order
# to add appropriate utterances
for slot, value in slot_values.items():
if slot == 'name':
if (bool(re.search(r'\d', value)) == False) and (
bool(re.search("[^a-zA-Z.\-\s\Ü\ü\ß\ä\Ä\ö\Ö]", value)) == False): # if hasNumber == False
slot_values[slot] = value
else:
dispatcher.utter_template('utter_spezial_characters', tracker)
# validation failed, set slot to None
slot_values[slot] = None
# validation succeed, set the slots values to the extracted values
return [SlotSet(slot, value) for slot, value in slot_values.items()]
As you can see, the slos that I want to export is
name
Hope you can help me!
