Lecture Features ✨

A lecture that deals with Django deeply and sincerely

This course is designed to help you understand and utilize Django correctly. I sincerely wanted to convey Django's design philosophy. The following are excerpts from Django's design philosophy .

1. Django uses the minimum amount of code possible, avoiding boilerplate code.
2. The main focus of a 21st century web framework is to speed up web development. Django should enable incredibly fast web development .
3. Duplication is bad, normalization is good. Django encourages you to not repeat yourself (DRY) and to create the most with the least amount of things.

In-depth coverage of both the backend and frontend in one lecture.

There is no royal road. It is just learning steadily and step by step. Come on that path with me. I will become your Python/Django/React pacemaker. Below is a quote from JangOO’s course review.

A lecture that combines 13 years of practical experience with Django and 6 years of Q&A experience from a developer who is serious about Django

1. I have been using Python since 2004 (version 2.4) and Django since 2008 (version 1.0) 1.0 (2008), and have practical experience in carrying out various web service/embedded/factory automation (FA) projects with Django and Python.
2. Experience answering various questions related to Django/Crawling/Python through the Ask Django community since 2015
3. Thousands of hours of Django/Python offline lecture experience since 2015
4. This is not a newly created course. It is a course that has been continuously refined and upgraded through 6 years of offline and online lectures . It will continue to be upgraded in the future.

A teacher who loves asking deep questions

We welcome all kinds of questions. Any questions related to Django/React, even if they are not covered in the lecture, are welcome. There is no such thing as a stupid question in the world. Please ask various questions. Let's think together and grow together.

I like the old life coding article by Egoing, so I'm quoting it.

As an aside, the more trouble the questioner has, the better the answer will be. Also, if you describe the process of solving the question along with the solution, it will be helpful for later searches and will be a great help to others.

Unlimited access and continuously updated courses

In order for this lecture to be a reference for Django, and to avoid outdated content, I promise to continuously update the changed Django functions. I will try to make this a lecture that continues to evolve. You can finish the basics of Django with this one lecture. If there is anything I missed, please let me know. I will reflect it immediately.

Slide-based theory lectures, and PDF provided

The slides used in all theory chapters have been refined and polished over many years of lectures. They are also provided as PDF files, so you can take the lectures while taking notes.

I have also carefully added links to official documents that you may find useful to refer to in the PDF document. Please read the relevant official documents whenever you have time. Django has really well-organized official documents. The answers are in the official documents. You should make it a habit to look at the official documents. That way, your skills will improve quickly. Don't start by Googling, but if you do, if you Google accurately, the official documents will probably come up.

_{I added a link to the official Django documentation to the document.}

All hands-on code is shared via a GitHub repository.

All the practice details are committed to the repository below. This is convenient if you want to check the practice details with your own eyes.

Things to prepare before class ✔️

The most important thing is your enthusiasm for development and persistence. You can't understand everything at once. Only persistent practice can improve your skills. I will be your pacemaker on that journey.

I strongly recommend that you become familiar with the basics of Python syntax before starting this course. At the very least, please review Python functions/classes/inheritance/first-class functions/decorators before starting.

Among these, inheritance and decorators are essential grammars for understanding and customizing various functions of Django. The decorator concept is similarly applied to React's HOC (Higher Order Components). Since Python and JavaScript are scripting languages, they have many similar grammars.

What you will gain by following this lecture faithfully 📜

You will be able to build a solid foundation for understanding the web, Django backend, and React frontend development. Through this, you will be able to create simple Instagram/Baedal Minjok services in no time. Of course, you cannot reach this level by simply listening to the lecture once and following the code. Attend the lecture diligently, think about it, ask questions, and develop.

Once you understand Django well, you can quickly start using Python web frameworks such as Flask or FastAPI. They may seem different, but they are similar because they are all web frameworks developed in Python. You can mix and match them in one service as needed.

In the last chapter, we will also explain in detail about deployment using Docker containers. If you use this, you can deploy web services more easily regardless of language/framework on various cloud vendors :-)

What you'll learn 📚

Orientation (2 sessions, 32 minutes)

Let's understand the technical background of Django and React.

Django Overview (5 lessons, 51 minutes)

We will set up the Django development environment and look at the core functions of Django. And in order to experience the power of Django, we will conduct a Django blog development live coding show. The source code editor will use Visual Studio Code, and we will explain the development environment settings centered on Windows.

Database processing using Django Models (Lecture 14, 4 hours 2 minutes)

Understand each function of Models, Django ORM, and learn how to use models to perform database CRUD.

Handling HTTP requests using Django Views (Lecture 12, 3 hours 37 minutes)

Let's understand the different ways to handle HTTP requests through Django Views.

Web Frontend Basics and How to Handle Static Files in Django (Lecture 6, 1 hour 46 minutes)

Learn the most basic web front-end HTML/CSS/JS development methods and how to place CSS/JS files within a Django project.

Efficient Data Validation and Storage Using Django Forms (Lecture 9, 3 hours 4 minutes)

Learn validation using Django Forms and how to use it in View. All data sent to the server should never be trusted and must be validated before being reflected in the DB.

For example, if a request for withdrawal of 1 million won comes from the bank, you should check if there is 1 million won in the balance before making the withdrawal. It may seem obvious, but many people develop programs to process withdrawals of 1 million won without checking the balance. They find validation cumbersome or difficult, so they say they will implement it first and then leave it for later.

These Djangos are well-linked with various functions to systematically perform validation. If you know Django well, you can perform systematic validation with minimal code and manage our service more safely. Isn't it the purpose of using a web framework to make good use of and enjoy these functions? You can see as much as you know and use as much as you know. Just typing is not development .

Implementing Django Basic Authentication (Lecture 7, 57 minutes)

It is an essential function that must be taken care of in the service authentication security. There are various vulnerabilities on the web, and it may be difficult to take care of these vulnerabilities one by one. Django provides almost all the functions required for authentication in Django Basics. The authentication function is guaranteed and maintained by the Django team.

Just because you use the features provided by the Django team doesn't mean you're blocked from customizing. It's well designed so that we can customize as much as we want. If you follow the default logic of the auth app 100%, there's almost nothing to code. Let's implement login/logout/signup functions by making full use of the auth app, which is the default Django app.

Creating an Instagram St using Django Forms/Views in a non-SPA manner (Lecture 23, 7 hours 5 minutes)

Now it's time for practice. Let's develop an Instagram St service together, making full use of Django's features.

Creating an efficient web API using Django django-rest-framework (hereinafter referred to as DRF) (Lecture 15, 5 hours 45 minutes)

Django's basic features are focused on implementing web pages. They can be used for developing web APIs, but they do not 100% match the usage. That is why DRF, which focuses on developing web APIs, was developed. DRF is not a separate library from Django, but a library that follows Django's design philosophy. DRF's Serializer follows the philosophy of Django's basic Form. DRF's ViewSet/APIView was developed based on Django's basic CBV. Therefore, in order to use DRF well, you must be good at Django's basics to 100% understand and utilize its functions.

Learning ES6+ Grammar and React Basics (24 lectures, 9 hours 26 minutes)

Learn ECMAScript 6 (ES6) grammar and the core concepts of React.

Creating Instagram in SPA style with React (21 lectures, 6 hours 53 minutes)

Up to the previous section, we have learned all the basic theories required for Django/React development. Now , it is time to practice mixing React and Django together. Let's develop the Instagram St. service together by making full use of the functions of Django/React. In this lecture, we will not implement all the functions of Instagram St. Since many of the necessary service functions have similar technical implementations, we will explain the core service functions without duplication.

Deploying Django/React services on AWS/Azure infrastructure based on containers (Lecture 14, 3 hours 29 minutes)

Learn about the need for container-based service deployment, how to install Docker, and how to build and deploy Docker images.
