Fetching data from mongo-tracker in ' Rasa' and storing it in mongoDB at runtime like sender_id,timestamp - mongodb

Question

Could you please tell me how are you fetching specific details from the tracker store. Elaborating my doubt below:
in my run_app.py (socketIO class) i have used mongotracker like this-
db = MongoTrackerStore(domain=“d.yml”,host=‘host ip’, db=‘xyz’, username=“x”,password=“x”,collection=“x”,event_broker=None)
agent = Agent.load(‘models/dialogue’, interpreter=‘models/current/nlu’,action_endpoint = action_endpoint,tracker_store=db)
now i want to fetch some data like db.sender_id or db.event. the reason of doing it is to store it column wise on my mongodb.Please help me solving this problem.

Answer 1

This information should already be stored in your mongodb, so there should be no extra need for you to store it.
Maybe see the documentation for this https://rasa.com/docs/core/tracker_stores/ and make sure your endpoints.yml file includes the correct information:
tracker_store:
store_type: mongod
url: <url to your mongo instance, e.g. mongodb://localhost:27017>
db: <name of the db within your mongo instance, e.g. rasa>
username: <username used for authentication>
password: <password used for authentication>
auth_source: <database name associated with the user’s credentials>
For information on how to fetch specific details from your mongodb maybe have a look at the mongodb docs https://docs.mongodb.com/manual/reference/method/db.collection.find/.

Answer 2

look at this Example
I am using Pymongo to connect monogoDB. try to understand my code
from typing import Any, Text, Dict, List
from pymongo.database import Database
from pymongo import MongoClient
from rasa_sdk import Action, Tracker
from rasa_sdk.executor import CollectingDispatcher
import pymongo
# url="http://localhost:3000/api"
client = pymongo.MongoClient("localhost", 27017)
db=client.sample
class mercdesCarAction(Action):
def name(self):
return "mercdesCarAction"
def run(self,dispatcher,tracker,domain):
res = db.datas.find({'action':'mercdesCarAction'})
for i in res:
dispatcher.utter_button_message(i['text'],i['buttons'])
return []
