app = Flask(__name__)

@app.route('/')
def home():
    return render_template('home.html')

@app.route('/post', methods=['POST'])
def create_post():
    # Logic to process form data and save a new blog post
    title = request.form['title']
    content = request.form['content']
    # Save post logic here...
    return 'Post created!'
        
if __name__ == '__main__':
    app.run(debug=True)

Simple Django Task Management System

        
from django.db import models
from django.shortcuts import render, redirect

class Task(models.Model):
    title = models.CharField(max_length=100)
    completed = models.BooleanField(default=False)

def task_list(request):
    tasks = Task.objects.all()
    return render(request, 'task_list.html', {'tasks': tasks})

def add_task(request):
    if request.method == 'POST':
        title = request.POST['title']
        Task.objects.create(title=title)
        return redirect('task_list')
    return render(request, 'add_task.html')
