Django Project Structure

Project Directory:

The project directory is the root of your application. It contains various subdirectories, including settings, urls, and apps.

Settings.py:

The settings.py file configures your Django project. It defines database connections, installed apps, and other project-specific settings.

URLs.py:

This file maps URLs to views in your application. It defines the routing logic, determining which view should handle each URL request.

Create an App: Create a new Django app using the “django-admin startapp” command.
Configure Your Project: Add your app to the INSTALLED_APPS setting in your project’s settings.py file.
Run the Development Server: Start the development server using the “python manage.py runserver”command.

Creating Models in Django Python

Models in Django Python represent the data structure of your application. They are defined using Python classes and are mapped to database tables.

Here’s a simple example of a BlogPost model:
Python from django.db import models
class BlogPost(models.Model):

title = models.CharField(max_length=200)

content = models.TextField()

# myapp/templates/myapp/index.html

<!DOCTYPE html>

<html>

<head>

<title>Django Example</title>

</head>

<body>

<h1>Hello, {{ name }}!</h1>

</body>

</html>

<body>

<ul>

{% for blog_post in blog_posts %}
