Django is a high-level web framework written in Python that encourages rapid development and clean, pragmatic design. It follows the model-view-template (MVT) architectural pattern, which is similar to the model-view-controller (MVC) pattern commonly used in web development. Django is designed to be easy to use and allows developers to build web applications quickly and efficiently.
In this tutorial, we will cover the basics of Django, including setting up a development environment, creating a new project, setting up a database, creating models, views, and templates, and deploying the application to a production server. This tutorial is designed for beginners who are interested in learning how to build web applications using Django.
Setting up a development environment
Before we can start building web applications with Django, we need to set up a development environment. The first step is to install Python on your computer. Django requires Python 3.6 or higher, so make sure you have the correct version installed.
Next, we need to install Django using pip, which is the package manager for Python. Open a terminal or command prompt and run the following command:
pip install django
This will install the latest version of Django on your computer. Once Django is installed, we can create a new Django project.
Creating a new project
To create a new Django project, run the following command in the terminal:
django-admin startproject myproject
Replace “myproject” with the name of your project. This command will create a new directory with the project structure and configuration files for your Django project.
Setting up a database
Django uses an object-relational mapping (ORM) system to interact with databases. By default, Django uses SQLite as the database backend, but you can configure it to use other databases such as PostgreSQL, MySQL, or Oracle.
To set up a database for your Django project, open the settings.py file in the myproject directory and update the DATABASES setting with the database configuration. For example, to use PostgreSQL, you would configure the DATABASES setting like this:
DATABASES = {
‘default’: {
‘ENGINE’: ‘django.db.backends.postgresql’,
‘NAME’: ‘mydatabase’,
‘USER’: ‘myuser’,
‘PASSWORD’: ‘mypassword’,
‘HOST’: ‘localhost’,
‘PORT’: ‘5432’,
}
}
Once you have configured the database settings, you can create the database by running the following command in the terminal:
python manage.py migrate
This will create the necessary tables in the database for your Django project.
Creating models, views, and templates
Models in Django are used to define the data structure for your application. To create a new model, open the models.py file in the myapp directory and define a new class that extends the models.Model class. For example:
from django.db import models
class Post(models.Model):
title = models.CharField(max_length=100)
content = models.TextField()
created_at = models.DateTimeField(auto_now_add=True)
Once you have defined your models, you can create views to handle the logic for your application. Views in Django are Python functions that take a request object and return a response object. To create a new view, open the views.py file in the myapp directory and define a new function. For example:
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})
Finally, you can create templates to display the data in your application. Templates in Django are HTML files that include template tags and filters to dynamically render data. To create a new template, create a new directory called templates in the myapp directory and create a new HTML file. For example, create a file called post_list.html with the following content:
{% for post in posts %}
{{ post.title }}
{{ post.content }}
{% endfor %}
Deploying the application to a production server
Once you have finished building your Django application, you can deploy it to a production server. There are several ways to deploy Django applications, but one common method is to use a platform-as-a-service (PaaS) provider such as Heroku or PythonAnywhere.
To deploy your Django application to Heroku, you can follow these steps:
1. Create a Heroku account and install the Heroku CLI on your computer.
2. Create a new Heroku app using the Heroku CLI.
3. Set the Django secret key as an environment variable on Heroku.
4. Configure the DATABASES setting to use a PostgreSQL database on Heroku.
5. Push your Django project to the Heroku app using git.
Once your Django application is deployed to a production server, you can access it using a web browser and start using your web application.
In this tutorial, we covered the basics of Django, including setting up a development environment, creating a new project, setting up a database, creating models, views, and templates, and deploying the application to a production server. Django is a powerful web framework that allows developers to build web applications quickly and efficiently. By following this tutorial, you can start building web applications with Django and take your Python programming skills to the next level.

one of the worst aspects of learning web dev in youtube is that you don't have access to table of contents and the underlying principles of things that is very important to understand what is going on. only the old timers understand what is of importance is missing. and this course is the best in this scope. instead of just jumping into the django itself it tries to teach what problems we have in web and then how django can help us in that manner . this is a full course about web development and it is in my view a gold mine.
The video quality is 🎉
Can I start Freelancing after completion of this course or can I able to land on a job after this course
Great to learn from you sir, I am honored to learn from one of the ideal teachers. Love and Regards, Asst. Prof. Syed Faisal Ali
27:00 Accurate Hacking is portrayed in Mr Robot
Going to start this on 2nd june, and will not quit until i complete it.
wow…I'm gonna deep dive in this for sure! Look at this table of contents! Thanks Charles!
That's the most complete web development YouTube course I have ever watched.
I have never seen someone teaches how the server side really worked, normally a course like that starts directly at "Installing Django"
I tried every django book/tutorial many of which were paid. But this is hands down the BEST ONE to learn django.
i judge yes i judge
08:29:51 Install django-extensions
Is this course still valid in 2024?
this men made me the SWE i am today. thank you sir
2/10 for this course, no examples for practice
I am grateful for your effort. Thanks a lot
Very informative content. Plenty of useful and valuable material here. However, this is not where you want to learn Django for your first time. I will say come back here after you know how Django works, and use this as a reference. The Dr presents the material in a "how-to" manner. That's to say he basically narrates the procedures. The "why" is largely missing, and thus new learners will find it hard to see the big picture. However, after you have a working knowledge of Django, come back here for great revision, then write to the Dr. and thank him for such dedication.
cool video)
