MindsDB is a predictive AI layer for existing databases that enables you to build and deploy machine learning models effortlessly. Here's why MindsDB is an excellent choice for building chatbots:
- Ease of Use: MindsDB provides a straightforward API for training and deploying models, making it accessible even for those with minimal machine learning experience.
- Integration: It seamlessly integrates with your existing databases and applications, reducing the overhead of data migration.
- Performance: MindsDB leverages powerful machine learning algorithms to deliver accurate predictions and responses.
Project Overview
Here's a quick overview of our project structure:

Step 1: Training the MindsDB Model
First, we need to train our MindsDB model using the chatbot data. We'll assume you have a CSV file (reformatted_chat_data.csv) with columns input and response.
from mindsdb import MindsDB
# Initialize MindsDB
mdb = MindsDB()
# Train the model using the reformatted data
mdb.train(
name='chat_model',
from_data='reformatted_chat_data.csv',
to_predict='response'
)
Step 2: Bot Logic and Advanced Features
We'll define the main logic for interacting with MindsDB and include advanced features like sentiment analysis, logging, rate limiting, and custom commands.
from mindsdb import MindsDB
from textblob import TextBlob
import logging
import time
from collections import defaultdict
# Initialize MindsDB
mdb = MindsDB()
project = mdb.get_project('chat_model')
# Initialize logging
logging.basicConfig(level=logging.INFO, filename='bot.log', filemode='a',
format='%(asctime)s - %(name)s - %(levelname)s - %(message)s')
# Rate limiting configuration
rate_limit_window = 60 # 1 minute
rate_limit_max_requests = 5
user_request_log = defaultdict(list)
def analyze_sentiment(text):
analysis = TextBlob(text)
return analysis.sentiment.polarity
def get_response(input_text):
prediction = project.predict(when={'input': input_text})
return prediction['response']
def get_response_with_sentiment(input_text):
sentiment = analyze_sentiment(input_text)
response = get_response(input_text)
if sentiment < 0:
response = "It seems like you're having a tough time. " + response
elif sentiment > 0:
response = "I'm glad to hear that! " + response
return response
def safe_get_response(input_text):
try:
response = get_response_with_sentiment(input_text)
except Exception as e:
response = "Sorry, I encountered an error while processing your message."
logging.error(f"Error: {e}")
return response
def log_interaction(platform, user, message, response):
logging.info(f"Platform: {platform}, User: {user}, Message: {message}, Response: {response}")
def rate_limited(user):
current_time = time.time()
request_times = user_request_log[user]
# Remove requests that are outside the rate limit window
user_request_log[user] = [t for t in request_times if current_time - t < rate_limit_window]
if len(user_request_log[user]) >= rate_limit_max_requests:
return True
else:
user_request_log[user].append(current_time)
return False
def handle_command(command, user):
if command == "/help":
return "Here are the commands you can use: ..."
elif command == "/info":
return "This bot helps you with ..."
else:
return "Unknown command. Type /help for the list of commands."
def process_message(message):
if message.startswith("/"):
command = message.split()[0]
return handle_command(command)
else:
return safe_get_response(message)
Step 3: Implementing Platform-Specific Bots
Slack Bot
import os
from slack_bolt import App
from slack_bolt.adapter.socket_mode import SocketModeHandler
from config import SLACK_BOT_TOKEN, SLACK_APP_TOKEN
from bot_logic import process_message, log_interaction, rate_limited
app = App(token=SLACK_BOT_TOKEN)
@app.message("")
def handle_message_events(message, say):
user = message['user']
user_message = message['text']
if rate_limited(user):
say("You are sending messages too quickly. Please wait a while before trying again.")
return
response = process_message(user_message)
log_interaction('Slack', user, user_message, response)
say(response)
def start_slack_bot():
handler = SocketModeHandler(app, SLACK_APP_TOKEN)
handler.start()
Twitter Bot
import os
import tweepy
from config import TWITTER_API_KEY, TWITTER_API_SECRET_KEY, TWITTER_ACCESS_TOKEN, TWITTER_ACCESS_TOKEN_SECRET
from bot_logic import process_message, log_interaction, rate_limited
auth = tweepy.OAuthHandler(TWITTER_API_KEY, TWITTER_API_SECRET_KEY)
auth.set_access_token(TWITTER_ACCESS_TOKEN, TWITTER_ACCESS_TOKEN_SECRET)
api = tweepy.API(auth)
class MyStreamListener(tweepy.StreamListener):
def on_status(self, status):
user = status.user.screen_name
user_message = status.text
if rate_limited(user):
return
response = process_message(user_message)
log_interaction('Twitter', user, user_message, response)
api.update_status(f"@{user} {response}", in_reply_to_status_id=status.id)
def start_twitter_bot():
myStreamListener = MyStreamListener()
myStream = tweepy.Stream(auth=api.auth, listener=myStreamListener)
myStream.filter(track=['@YourTwitterBotHandle'])
Discord bot
import os
import discord
from config import DISCORD_TOKEN
from bot_logic import process_message, log_interaction, rate_limited
client = discord.Client()
@client.event
async def on_message(message):
if message.author == client.user:
return
user = str(message.author)
user_message = message.content
if rate_limited(user):
await message.channel.send("You are sending messages too quickly. Please wait a while before trying again.")
return
response = process_message(user_message)
log_interaction('Discord', user, user_message, response)
await message.channel.send(response)
def start_discord_bot():
client.run(DISCORD_TOKEN)
Step 4: Starting the Bots
We'll use multiprocessing to start all bots simultaneously.
from multiprocessing import Process
from slack_bot import start_slack_bot
from twitter_bot import start_twitter_bot
from discord_bot import start_discord_bot
if __name__ == "__main__":
slack_process = Process(target=start_slack_bot)
twitter_process = Process(target=start_twitter_bot)
discord_process = Process(target=start_discord_bot)
slack_process.start()
twitter_process.start()
discord_process.start()
slack_process.join()
twitter_process.join()
discord_process.join()
Step 5: Installtion and Setup
Create a requirements.txt file to list the required dependencies.
requirements.txt
mindsdb
slack-bolt
tweepy
discord.py
textblob
python-dotenv
Install the dependencies:
pip install -r requirements.txt
Create a .env file in the project root and add your API tokens and keys:
SLACK_BOT_TOKEN=your_slack_bot_token
SLACK_APP_TOKEN=your_slack_app_token
TWITTER_API_KEY=your_twitter_api_key
TWITTER_API_SECRET_KEY=your_twitter_api_secret_key
TWITTER_ACCESS_TOKEN=your_twitter_access_token
TWITTER_ACCESS_TOKEN_SECRET=your_twitter_access_token_secret
DISCORD_TOKEN=your_discord_bot_token
Step 6: Running the Project
Train the MindsDB model using the provided script. Then, run the main script to start all the bots:
python main.py
