MongoDB Storage Adapter

Before you can use this storage adapter you will need to install pymongo. An easy way to install it is to use the chatterbot[mongodb] extra when installing ChatterBot. For example:

pip install chatterbot[mongodb]

You’ll also need to have a MongoDB server running. An easy way to run one locally is to use Docker:

docker-compose.yml

version: "3.8"

services:
  mongo:
    # Use the latest stable version of the mongo image
    image: mongo:8.0
    # Expose the default MongoDB port
    ports:
      - "27017:27017"
    # Persist the MongoDB data
    volumes:
      - ./.database/mongodb/db:/data/db

To start the MongoDB container, run:

docker compose up -d

Note

For more information on Docker and docker compose, see the Docker Compose documentation.
