Almost all the features needed for backend development
It is supported by Django .
Don't reinvent the wheel. Django supports almost all the features you need for backend development. Enjoy Django, reduce repetition, and save your time. Maximize your development productivity, significantly reduce the code you need to develop, and improve the readability of your code with Django/React.
To do that, you need a solid foundation in Django/React. You can build that foundation solidly through this one lecture.

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 .
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.
To be honest, there were many difficult parts when I first heard it... but after listening to it over and over again and repeating it, I felt that there was no better lecture for grasping the concepts. The best part was that it taught me how to use it in conjunction with React, so I was able to create both the front and back ends with my own hands and see the results for myself, which was really great.
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.
<The Art of Asking Universal Questions from Coding Night School>
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.
In order for this lecture to be a reference for Django, and to avoid outdated content, I promise to continuously update the changed Django functions.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.
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.
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.
Please check your player knowledge!
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.
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 :-)
Let's understand the technical background of Django and React.
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.
Understand each function of Models, Django ORM, and learn how to use models to perform database CRUD.
Let's understand the different ways to handle HTTP requests through Django Views.
Learn the most basic web front-end HTML/CSS/JS development methods and how to place CSS/JS files within a Django project.
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 .
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.
Now it's time for practice. Let's develop an Instagram St service together, making full use of Django's features.
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.
Learn ECMAScript 6 (ES6) grammar and the core concepts of React.
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.
Learn about the need for container-based service deployment, how to install Docker, and how to build and deploy Docker images.
Q. Is this a lecture that non-majors can also take?
This is a proven lecture that has been conducted for non-majors for several years. If you understand the basic grammar of Python, you can follow it. Of course, you may not understand it after listening to it once. There is no one who understands it after listening to it once. Don't be too disappointed. It is natural because you are learning an unfamiliar field. Efforts with a clear direction will not betray you. Please watch it several times, think about it, and learn. If you still have doubts, please ask questions right away. Let's work through it together. :-)
Q. Isn't Python a beginner's language?
Python is more readable than other languages, and can efficiently perform many tasks with short codes. Although Python has not been popular in Korea for very long, it has been a major language overseas for more than a decade, and is actively used in various fields including the web.
And Python is not slow. Just as English becomes Konglish if you don't understand it properly, Python code used without understanding Python properly is not efficient. If you understand and use Python well, you can quickly develop code that runs fast. Can we say that code developed in C runs fast in all cases? If you develop it to run slowly, it will run slowly. And although Python is slow in CPU operations, Python libraries developed in C/C++/Rust solve the parts that require fast CPU operations. Libraries like numpy. So, you can use Python to do data analysis and machine learning. :-) In fact, many of Kakao's machine learning APIs are developed in Python. (Reference: [YouTube - PyCon Korea] Application Server Development Review for Recommendation System @kakao )
Q. Isn't Django too expensive to learn, slow, and has too many limitations?
Django is a mature framework that has been around for over 17 years since it was released in 2005. (Spring was released in 2003.) Django is a full-stack backend framework, and almost all the features required for backend development are developed and being developed within Django.
Django is just a single Django that provides many features. Having many features does not mean that it is slow. Micro web frameworks like Flask provide fewer features. Having fewer features does not mean that it is fast.
The first of Django's design philosophies is "loose coupling." Django provides a variety of functions in a full stack for convenience, but each function is independent. You can select and use only the functions you need, and you can combine them with various Python libraries.
Toss has an organization called "Toss Internal" that creates services for the 1,000 or so Toss team members. This organization develops services with Django and React. ( Related job posting for Toss: Server Developer (Internal Product) ) Why did the Toss Internal team choose Django and React?
Q. To what extent does the course cover Django/React?
We cover all the basic technologies of Django required for basic web service configuration. Django channels and Celery are not covered. In React, we cover everything required for basic web service configuration except Redux. The reason Redux is excluded is that although many people are still using Redux, I think it is a technology that unnecessarily increases the complexity of React applications. Redux is a technology that came out when React did not have a proper state management technology. There are various state management technologies now. Among them, we will take a deep look at Hooks and Context API.
Q. Is there a practical environment that I need to prepare before taking the course?
Any environment where Python and nodejs can be installed is possible. Windows/Linux/Mac environments are all good. If you have difficulty installing Python/nodejs, try using the cloud IDE service . You can use the Linux environment with a web browser.
On Windows, we recommend Windows 10 Pro or higher for easy Docker Desktop installation. Windows 10 Home may require registry modifications, which can be troublesome. Since the Cloud IDE service is a service powered by Docker, running Docker inside the Cloud IDE container is not possible.
This course was originally provided on another platform, but has been transferred to Inflearn. We are sharing our course reviews from the previous platform.

It really explains in detail, focusing on very detailed concepts. It may be difficult at first, but as the concepts accumulate, I think I understand them deeply, so I was really satisfied!! I definitely recommend that you study at least the basics of Python and listen to it. It covers everything from the basics of Django to deployment. I also really liked the part where he gives tips that are hard to understand when studying alone.

I would like to thank instructor Lee Jin-seok for creating this course. I am still taking the course, but as each chapter progresses, my questions are being answered. I bought several books about Django and took courses related to Django to learn on my own, but it was very difficult to learn the in-depth parts of Django by myself. There were many parts that I used without understanding and thought, “What? How can I do it?”. As I listened to instructor Lee Jin-seok’s course, I think I learned why it works this way, what its structure is, and how to use it. The course progresses sequentially, such as admin > model > view, but each chapter is taught with consideration for connectivity, and the content is also deep, so it seems like a great course for beginners to intermediate users like me. Also, while working with Django, I thought a lot about the front-end, and I thought about integrating Django with Vuejs and other front-end tools, but I chose this course, which is a one-shot package, because I thought it would take time and a headache to learn on my own. 154,000 won is not a small amount of money, so I hesitated a lot before paying. However, after paying and listening to the lecture, I felt that the lecturer had really thought a lot about this course, and I did not regret the money spent. The chapter progression is smooth, and the tone of voice is also good for concentrating on the course. It is a shame that the course period is limited to 180 days, but that is a matter of how faithfully I study and acquire the course materials. 😭😭 The course materials are solid, so if I acquire them well through repeated study for 180 days, I think I will be able to remember and utilize them just by looking at the course materials that were created later.
Mr. HaOO
This is the most informative lecture I've ever taken. Since he has a lot of experience, he immediately deals with any errors that he encounters, so the flow of the lecture is not interrupted. His explanations are very clear, and he skips over content that needs a lot of explanation and explains it step by step throughout the lecture. I think the lecture is very well structured. I also have teaching experience, so I know that he puts a lot of effort into the lecture. It's on a different level from YouTube-style web lectures. It's a really informative lecture that covers everything from the basics to deployment. If a friend wants to learn Django or React, I definitely recommend it. I paid the full 220,000 won, but it was worth it. You need to know basic Python grammar, and you don't need to know JavaScript at all. If you just know Python grammar, I think it's a lecture that even non-majors can listen to smoothly.

First of all, thank you so much for making such a great lecture!! I heard that it was a really good lecture, so I trusted it and paid for it, and as expected, unlike other lectures, it was a lecture that I didn't regret spending money on. If you follow it properly from beginning to end, it will take longer than the lecture time, but that time will definitely not be a waste. It's a lecture that's too good to watch once. I highly recommend it to those who feel like they lack basic skills :)
Mr. HyunOO
I wish there were more lectures like this. Django itself has a lot of abstract parts, so it's easy to make something, but there were many cases where I didn't understand the internals. In that sense, the part where you explained the internal code was very helpful. I was so impressed that I even wrote a review on my blog recommending it. Thank you :)
Mr. Lee OO
I took the lecture at askcompany and I want to pay again and do it properly this time. It is very helpful, from the basics to the details. I couldn't listen for a while since the semester started, but I will try to listen to it again even if I have time. Thank you for making such a great lecture. 'Life is short. Use Python and Django.' The saying comes to mind. I will work hard.
Mr. HanOO
I usually do various tasks with Python and upload APIs using Flask, but at some point, I started to need to do more work with Django, so I'm listening to this. Since you create examples one by one with code, you can learn the necessary parts very easily and in a short period of time. If you need to study Django, I highly recommend it!
Mr. Yang OO
This is a really good lecture. I had to analyze and modify open source made with react and django, so I'm learning react and django in a short period of time. It's difficult, but I'm learning well because you explain it well. I only did applications, but I had no concept of full-stack development of web programs with react and django, but it's very helpful. The information you give me as tips here and there is also very useful. I think it would have been difficult just with the book. There's a lot to learn and know. I'm still listening, but I'm very happy that I'm learning about the latest web technologies through this opportunity. Thank you so much for making this lecture.
Mr. OO
I highly recommend it. It is the most satisfying course among the courses I have paid for. You may think the price is a lot, but it is a course that is filled with Lee Jin-seok's passion, effort, and know-how. :) It is the most detailed Django course in Korea!
Mr. ROO
The detailed lectures are really good. At first, when I didn't know anything, I had a headache because I didn't know what he was talking about, but after listening to it for the second time, I realized that he was explaining things in order to help me understand the basics. I'm still taking the class, but I don't regret paying the tuition fee~
Mr. KaOO
I am studying happily because the instructor explains everything thoroughly. I originally studied Django and made a homepage with Django template, but after studying React, I was at a loss as to how to connect with API and how to distribute it. After taking the instructor's class, I feel like my mind has been cleared up a bit! If there is something confusing, I keep listening and repeating it, and then I understand it. Thank you. I will run until the end!
I am Jinseok Lee, a software developer who is passionate about Python and Django.

ジュニアジャンゴ開発者として働いており、整理次元で講義を受講することになりました。 私が受講したジャンゴ講義の中で深くてノウハウが溶けている講義だと思います。 個人的に良かった部分です。 - 単純画面を抜くのではなく、コンポーネントベースのコード構造に対する悩みが溶けている - ORMの活用とクエリのチューニング。 - Django MTVパターン構造の概念 - djangoまたはDRFでの関数型、クラス型ビューの適切な活用 良い講義に感謝し、他の講義もオープンしたら受講したいと思います。 Django Channels、セロリなどを活用した非同期高級講義もぜひ開いていただきたいと思いますファイティングです。

Pythonが流行になった2021年現在でも断然軍界一学です。国内外を統一し、「イ・ジンソクジャンゴ」にビビルほど他の名講義がないというのも学界の定説だと言いますㅎㅎㅎ 2017年ごろですか? Pythonに触れ始めたばかりの時(他サイトで)ジンソク様の講義に初めて接しました。 Pythonの基本文法から独学で学び、Webへの理解が全くなかったため、穴が多かったのですが、ジンソク様の講義が絹のジャンゴだけでなく、Pythonとプログラミングの基礎をつかむのにも大きな助けとなりました。 おかげで私は専門開発者でなくてもブログを直接作って運営する経験もしてみたし、簡単なウェブページ制作副業もすごく撃たせてみました。おすすめや紹介をたくさん聞いてくださって、別にプラットフォームや広告、広報をしなくても一ヶ月受講料の数十倍にもなる収益を得ました。 (私のような場合は幸運に自治体や中小規模のイベント業者で一時的に制作運営する地域フェスティバル、ㅇㅇフェスティバル、またはㅇㅇ公募展のウェブページ制作中心に行うことができました。 その際に比べるとジンソク様講義にリアクトやインスタグラムチュートリアル、AWSなどカリキュラムが多く追加されたのですが、焚き火に豆焼き食べるように一日二日の間に作った講義ではないという点に大きなスコアを差し上げたいと思います。じっくり煮込んだムクジや味噌のような味の講義です。うまく整えられていて過剰な部分がないという感じです。 (もちろん現職のウェブ開発者であれば話が異なるかもしれませんが、入門で初中級レベルならこれ一つで十分ではないかと思います。) 同僚や知人がPythonのWeb開発について推薦してもらうとき、私は一度も他の講義を話しませんでした。 &quot;インフラストラクチャの二進席&quot;のみをお勧めします。おやすみすると、これほど良い他の講義もありますか?と他のサイトを何度も探してみましたが、(もちろん良い講義は多少あったが)これだけの講義がなかったようです。 この講義をより強力に推薦したいのですが、私の筆力がここまでかと思いますㅜこれだけ減らします。最後に、生涯無制限の受講なので、必要な時点で参考にできるように、今回の生に一度は受講しておくことをお勧めします。幸せな一日をお過ごしください!
こんにちは先生。私もその講義を聞きながら "これをきちんと繰り返すと私もフルスタックウェブ開発をしてみることができる。 ところが遅い年齢だから新入は大変そうで、本人の意志は「フリーランスや自宅勤務で適度に長く働きたい。」やったことがありますか?
