is it possible to extract entity from the last user input text and only from that last input text? I am looking for a method similar to` tracker.get_latest_entity_values("PERSON")`, instead of extracting latest entity value of the entity “Person”, I want to extract entity person is present in the last user input text.

use case: A form that is used to collect personal details (slots: name, phone\_number, etc). After filling the slot `person_name` (filled by entity extraction) the user might request to change his name. If the user input contains entity PERSON (`"Can i change my name to Adam Jon"`) I need to update the old slot `person_name` with the entity value of `PERSON` and if the user text doesn’t have the Entity `PERSON` (`"Can I change my name?"')I need to update the slot value with `None`

`tracker.latest_message` is a dictionary containing the attributes of the latest message: `intent`, `entities`, and `text`.

So try `tracker.latest_message['entities']` and see if it has the entity `PERSON`.

is there a simple method something like `next(tracker.get_latest_entity_values('entity_type'), None)` that gives us all the values of an entity from last user input

eg : what is the `price` and `color` of the car? here price and color are of same entity ‘car\_attribute’, If I use `next(tracker.get_latest_entity_values('entity_type'), None)` i will get only one value .

I know i can loop through `tracker.latest_message['entities']` to resolve me issue, I am looking for simple method, If someone knows it please let me know

`tracker.latest_message['entities']` should contain all entities in your message
