Few weeks back I wrote a post Build your first ChatBot in 5 minutes.
That bot was cool and you can talk through terminal. Today, let’s try to build the same bot with Flask.
So, we will use ChatterBot which is a machine learning, conversational dialog engine for creating chat bots.
If you haven’t read my previous post go here
Install ChatterBot
$ pip install ChatterBot
Install Flask
$ pip install Flask
Create a file
app.py and open it
#import files
from flask import Flask, render_template, request
from chatterbot import ChatBot
from chatterbot.trainers import ChatterBotCorpusTrainer
from chatterbot.trainers import ListTrainer
Create a flask app
app = Flask(__name__)
and as we have seen in my previous post
bot = ChatBot("Candice")
bot.set_trainer(ListTrainer)
bot.set_trainer(ChatterBotCorpusTrainer)
bot.train("chatterbot.corpus.english")
and after this
@app.route("/")
def home():
return render_template("home.html")
@app.route("/get")
def get_bot_response():
userText = request.args.get('msg')
return str(bot.get_response(userText))
if __name__ == "__main__":
app.run()
So, as we can see we need to create a home.html file as a frontend.
Create a folder “templates” and inside that create a file home.html.
templates/home.html
Open home.html
<!DOCTYPE html>
<html>
<title>Candice</title>
<body>
<center>
<h1>
Your Personal ChatBot
</h1>
</center>
<div>
<p>
<center><span>Hi! I'm Candice your personal ChatBot</span></center>
</p>
</div>
<div id="userInput">
<input id="textInput" type="text" name="msg" placeholder="Message" />
</div>
</body>
</html>
So, this is just a basic structure let’s add some css to it. We are not creating another file for css, we are just adding style into home.html
<head>
<link
rel="shortcut icon"
type="image/x-icon"
href="https://user-images.githubusercontent.com/20112458/49326597-773b7280-f57a-11e8-853d-20ed61d18b0d.png"
/>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<style>
body {
font-family: monospace;
}
h1 {
background-color: yellow;
display: inline-block;
font-size: 3em;
margin: 0;
padding: 14px;
}
h3 {
color: black;
font-size: 20px;
margin-top: 3px;
text-align: center;
}
#chatbox {
margin-left: auto;
margin-right: auto;
width: 40%;
margin-top: 60px;
}
#userInput {
margin-left: auto;
margin-right: auto;
width: 40%;
margin-top: 60px;
}
#textInput {
width: 90%;
border: none;
border-bottom: 3px solid black;
font-family: monospace;
font-size: 17px;
}
.userText {
color: white;
font-family: monospace;
font-size: 17px;
text-align: right;
line-height: 30px;
}
.userText span {
background-color: #808080;
padding: 10px;
border-radius: 2px;
}
.botText {
color: white;
font-family: monospace;
font-size: 17px;
text-align: left;
line-height: 30px;
}
.botText span {
background-color: #4169e1;
padding: 10px;
border-radius: 2px;
}
#tidbit {
position: absolute;
bottom: 0;
right: 0;
width: 300px;
}
.boxed {
margin-left: auto;
margin-right: auto;
width: 78%;
margin-top: 60px;
border: 1px solid green;
}
.box {
border: 2px solid black;
}
</style>
</head>
Now, after that let’s change body structure.
<body>
<center>
<h1>
<img
src="https://user-images.githubusercontent.com/20112458/49326597-773b7280-f57a-11e8-853d-20ed61d18b0d.png"
alt="CANDICE"
style="width:40px;height:40px;"
/>Your Personal ChatBot
</h1>
</center>
<div class="box"></div>
<div class="boxed">
<div>
<div id="chatbox">
<img
src="https://user-images.githubusercontent.com/20112458/49326597-773b7280-f57a-11e8-853d-20ed61d18b0d.png"
alt="CANDICE"
style="width:40px;height:40px;"
/>
<p class="botText">
<span>Hi! I'm Candice your personal ChatBot</span>
</p>
</div>
<div id="userInput">
<input id="textInput" type="text" name="msg" placeholder="Message" />
</div>
</div>
</div>
</body>
Now, if we type something nothing will happen. So, let’s add some script
<script>
function getBotResponse() {
var rawText = $("#textInput").val();
var userHtml = '<p class="userText"><span>' + rawText + "</span></p>";
$("#textInput").val("");
$("#chatbox").append(userHtml);
document
.getElementById("userInput")
.scrollIntoView({ block: "start", behavior: "smooth" });
$.get("/get", { msg: rawText }).done(function(data) {
var botHtml = '<p class="botText"><span>' + data + "</span></p>";
$("#chatbox").append(botHtml);
document
.getElementById("userInput")
.scrollIntoView({ block: "start", behavior: "smooth" });
});
}
$("#textInput").keypress(function(e) {
if (e.which == 13) {
getBotResponse();
}
});
</script>
Now, you will see whatever you write will be shown on the ChatBox but your chatbot will not give any reply.
So, to do that let’s run your app.py
$ python app.py
So, go to the link and chat with your personal ChatBot
You can find the full source code on my Github.

Downgrade to python 3.7 time package does not work in python 3.8
Upgrading to the current version of SQLAlchemy (1.3.18 as of now) fixed the problem
