Polling Application with Flask – Beginner Project
Are you a beginner looking to build your first web application with Flask? Look no further! In this project, we will guide you through creating a simple polling application using Flask, a popular Python web framework. Let’s get started!
Prerequisites
Before we begin, make sure you have Python and Flask installed on your system. If not, you can easily install them using the following commands:
pip install flask
Setting up the Project
Create a new directory for your project and navigate to it using the terminal. Inside the directory, create a new file named app.py which will serve as the main entry point for your Flask application.
touch app.py
Creating the Polling Form
First, let’s create a simple HTML form to capture the user’s vote. In the app.py file, define a route to render the form:
from flask import Flask, render_template
app = Flask(__name__)
@app.route('/')
def index():
return render_template('index.html')
Now, create a new directory named templates within your project directory. Inside this directory, create a new file named index.html and add the following code for the polling form:
Cast Your Vote
Option 1
Option 2
Handling the Form Submission
Next, let’s add a route to handle the form submission and process the user’s vote. In the app.py file, define a new route:
@app.route('/submit-vote', methods=['POST'])
def submit_vote():
# Process the user's vote here
return 'Thank you for voting!'
Running the Application
That’s it! You have now created a simple polling application with Flask. To run your application, simply execute the following command in the terminal:
python app.py
Open your web browser and navigate to http://localhost:5000 to see your polling form in action. You can cast your vote and see the “Thank you for voting!” message upon submission.
Conclusion
Congratulations on building your first web application with Flask! This beginner project provides a solid foundation for understanding how to create and deploy web applications using Flask. We hope you found this tutorial helpful and encourage you to continue exploring the capabilities of Flask for building more sophisticated web applications.
Thank you NeuralNine, I have Idea to improve – you don't have to write csv manually: '''if not os.path.exists('polls.csv'):
structure= {
'id':[0],
'poll':[''],
'option1':[''],
'option2':[''],
'option3':[''],
'votes1':[0],
'votes2':[0],
'votes3':[0],
}'''
''' elif request.method == "POST":
poll = request.form['poll']
option1 = request.form['option1']
option2 = request.form['option2']
option3 = request.form['option3']
polls_df.loc[max(polls_df.index.values) + 1] = [poll, option1, option2, option3, 0, 0, 0]
polls_df.dropna(inplace=True) #add this line
polls_df.to_csv('polls.csv')
return redirect(url_for('index'))'''
very good
"….Nobody likes Java…." – what ? 🤣🤣🤣🤣🤣🤣🤣
What i'm missing from all your tutorial videos is it starting with a demo and an explanation of what it does.
hah, I was advised by chatgpt to look at you to study neural networks)
Thx_Nice.
Cool!
Hello, my wonderful friend, your videos are very beautiful and deserve a lot of support. I have a good suggestion, perhaps for you. Why don't you make your videos contain Arabic translation? With this step, you will get a lot of support from the Middle East and from all countries Those of you guys who agree with me put a like on my comment so that it appears to the owner of this beautiful channel and looks into this matter well. Thank you very much, my friends.
