Introduction to Django

Django is a high-level Python web framework that allows developers to build web applications quickly and easily. It was created to help developers take care of the "plumbing" involved in web development, so they could focus on building the core features of their applications. Django comes with a variety of built-in tools and features, such as an ORM, templating engine, and a robust admin interface.

Setting Up Your Development Environment

Before we start building our web application, we need to set up our development environment. First, you'll need to install Python on your machine. Once Python is installed, you can use pip, the Python package manager, to install Django. It's recommended to use a virtual environment to isolate your project's dependencies. You can create a virtual environment using the following command:

python -m venv myenv

After creating a virtual environment, activate it by running the appropriate command for your operating system. Then, you can use pip to install Django:

pip install django

Creating a Django Project

With Django installed, we can create our first project. A project in Django is a collection of settings, configurations, and apps that make up a web application. To create a new project, navigate to your desired directory and run the following command:

django-admin startproject myproject

This will create a new directory called myproject with the following structure:


└── myproject/

Creating a Django App

Now that we have our project set up, we can create a new app. An app in Django is a self-contained module that performs a specific function. For example, a blog app could be responsible for handling blog posts and comments. To create a new app, run the following command:

python startapp myapp

This will create a new directory called myapp with the following structure:



Creating a Model

A model in Django is a representation of a database table. It defines the fields and their types, as well as any methods or behavior associated with the data. To create a model, we'll define a class in For example, if we wanted to create a model for blog posts, we could define it like this:

from django.db import models

class Post(models.Model):
    title = models.CharField(max_length=255)
    content = models.TextField()
    pub_date = models.DateTimeField(auto_now_add=True)

Here, we define a Post model with three fields: title, content, and `pub

Creating Views

Now that we have our model, we can create views to handle user requests and render templates. Views in Django are Python functions that take a web request and return a web response. We'll create a simple view to display a list of blog posts in our file:

from django.shortcuts import render
from .models import Post

def post_list(request):
    posts = Post.objects.all()
    return render(request, 'post_list.html', {'posts': posts})

Here, we import the render function from django.shortcuts to render our template, and import our Post model. We define a post_list function that retrieves all posts from the database and passes them to our template.

Creating Templates

Templates in Django are HTML files that define the structure and layout of our web pages. We'll create a template called post_list.html in a new directory called templates within our app directory:


├── templates/
│   └── post_list.html
└── ...

Here's an example post_list.html template that displays our list of posts:

{% extends 'base.html' %}

{% block content %}
  <h1>Blog Posts</h1>
  {% for post in posts %}
    <h2>{{ post.title }}</h2>
    <p>{{ post.content }}</p>
    <p>{{ post.pub_date }}</p>
  {% endfor %}
{% endblock %}

Here, we use the extends keyword to inherit from a base template called base.html. We define a content block that will be filled in by our child templates. We use a for loop to iterate over our list of posts and display their fields.

Routing URLs

Now that we have our views and templates, we need to map them to URLs. We'll create a new file called in our app directory to define our URL patterns:

├── templates/
│   └── post_list.html
└── ...

Here's an example file that maps our post_list view to the /posts/ URL:

from django.urls import path
from . import views

urlpatterns = [
    path('posts/', views.post_list, name='post_list'),

Here, we import the path function from django.urls to define our URL patterns. We import our post_list view and map it to the /posts/ URL using the path function. We also give our URL pattern a name that we can use to reference it in our templates.

Testing Your Application

Now that we have our basic web application set up, we can test it by running the Django development server. In your terminal, navigate to your project directory and run the following command:

python runserver

This will start the Django development server and display a URL where you can view your web application in your web browser. Navigate to the URL and you should see a list of blog posts.

Deploying Your Application

Once you're satisfied with your web application, you can deploy it to a production environment. There are many options for deploying Django applications, such as Heroku, AWS, or DigitalOcean. You'll need to follow the specific instructions for your chosen deployment method to get your application up and running.


Building a basic web application with Django can seem like a daunting task at first, but with the right guidance and tools, it can be a straightforward

process. By following the steps outlined in this article, you can create a functional web application that stores data in a database, handles user requests, and renders templates. With further practice and learning, you can expand upon this basic application to create more complex and feature-rich web applications.
