Blog Platform in Python (Source Code)

Steps to create a simple blog platform:

1. Install the required packages.
2. Set up the application and database.
3. Implement routes for creating and viewing blog posts.
4. Create basic HTML templates for the user interface.

Step 1: Install Flask and SQLite3

Step 2: Create the Blog Application

Step 3: Code for app.py

from flask import Flask, render_template, request, redirect, url_for
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)
# Set up SQLite Database
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///blog.db'
app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False
db = SQLAlchemy(app)

# Create a Post model
class Post(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    title = db.Column(db.String(100), nullable=False)
    content = db.Column(db.Text, nullable=False)
    
    def __repr__(self):
        return f'<Post {self.title}>'

# Home route to display all blog posts
@app.route('/')
def index():
    posts = Post.query.all()
    return render_template('index.html', posts=posts)

# Route to create a new blog post
@app.route('/create', methods=['GET', 'POST'])
def create_post():
    if request.method == 'POST':
        title = request.form['title']
        content = request.form['content']
        new_post = Post(title=title, content=content)
        db.session.add(new_post)
        db.session.commit()
        return redirect(url_for('index'))
    return render_template('create.html')

# Route to view a single blog post
@app.route('/post/<int:id>')
def post(id):
    post = Post.query.get_or_404(id)
    return render_template('post.html', post=post)

if __name__ == '__main__':
    db.create_all()  # Create the database
    app.run(debug=True)

Step 4: Create HTML Templates (templates/base.html)

templates/index.html

templates/create.html

templates/post.html

Step 5: Basic CSS static/css/style.css

Step 6: Running the Application

To run the application, navigate to the project folder in the terminal and run the following command:
The app should now be running at http://127.0.0.1:5000/. You can visit the home page, create new posts, and view individual posts.

With this code, you can develop Blog Platform in Python to fit your needs.
