Django App - Python

Introduction

Django is a free and open-source web framework written in Python. It follows the model-template-view (MTV) architectural pattern and helps developers build web applications quickly and easily.

Features

Django offers a wide range of features that make it one of the most popular web frameworks. Some of the key features are:

• Object-Relational Mapping (ORM)
• URL routing
• Built-in forms and validations
• Admin interface
• Session management
• Security features such as cross-site scripting (XSS) prevention and cross-site request forgery (CSRF) protection
• Testing framework
• Internationalization and localization support

Getting Started

To get started with Django, you need to have Python installed on your machine. Once you have Python installed, you can install Django using pip.

pip install Django

Once you have Django installed, you can create a new Django project using the following command:

django-admin startproject projectname

This will create a new project with the name 'projectname'. You can then create a new app inside your project using the following command:

python manage.py startapp appname

This will create a new app with the name 'appname'. You can then build your web application within this app.

Code Snippet

from django.db import models
from django.contrib.auth.models import User

class Post(models.Model):
    title = models.CharField(max_length=255)
    content = models.TextField()
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    def __str__(self):
        return self.title

This is a simple model for a blog post. We have defined a 'Post' model with fields for the title, content, author, and creation/update timestamps. This model uses the Django ORM to interact with the database.
