Just imagine implementing the experience of the market leaders into your project. Doesn’t it mean that you have a chance to reach their success? Of course, it’s true! The only thing left is to study the 15 cases when companies made the step that 100% rebooted their product.
Fortunately for you, we have some great examples of products developed in Django and which are solid proof that this framework can be used in various industries.
When creating a website, you usually need to work with approximately the same set of basic components:
If the tasks are the same, why not simplify them and thereby reduce development costs? Web frameworks emerged as a collection of components designed to make it easier and simpler to build websites.
One such framework is Django. Django is gaining popularity, and many large companies use it to create web projects.
Django is considered the best web framework written in Python. This tool is useful for developing sites that work with databases. In this article, you will learn about Django and understand why it is a key link in the Python ecosystem.
Also, we have selected 15 popular portals that refer to the Django website development. Hurry up to see them!
Django was created by the developers of the Lawrence-Journal World. This newspaper needed a website to publish news on the Internet. Programmers Adrian Golovaty and Simon Willison created a web application and made it public.
A vibrant community has quickly emerged around Django. The framework began to develop rapidly through the efforts of volunteers. Several well-known sites that have used the framework have played a significant role in the success of Django. These include Pinterest, Dropbox, Spotify, The Washington Post. The Django community currently includes over 11,000 developers from 166 countries.
Django implements the DRY (don’t repeat yourself) principle. Thanks to this, the time for creating sites is reduced. That is, when using Django, you don't need to rewrite the same code multiple times. The framework allows you to create a website from components. It can be compared to building a fortress with Lego.
Django web systems are built from one or more applications, which are recommended to be made alienable and pluggable. This is one of the notable architectural differences of this framework from some others (for example, Ruby on Rails).
This framework is suitable for developing high-load web applications. This is possible thanks to the architecture of the framework, which will be discussed below.
The Django framework is written in the Python programming language, so its structure follows the language's specifics. The creators have implemented the MVC pattern in Django, and it is used in the current version of the framework.
The MVC architecture allows the developer to work with the application's visual presentation and business logic separately. By the way, when working with Django, experts often use the term MVT - Model-View-Template. MVT components can be used independently of each other.
The Django documentation defines a model as "a source of information about data that contains key fields and data behavior." Typically one model points to one table in the database. Django supports PostgreSQL, MySQL, SQLite, and Oracle databases.
Models contain information about data. This data is represented by attributes or fields. Since the model is a simple class, it doesn't know anything about Django's other layers. Interaction between the layers takes place through the API.
The model is responsible for business logic, methods, properties, and other data manipulation elements. Models also allow developers to create, read, update, and delete objects in the database.
The view solves three problems:
That is, the view receives data from the model and provides templates access to this data or preprocesses the data and then makes it available to templates.
Django has a powerful templating engine and its own markup language. Templates are files with HTML code that display data. The content of the files can be static or dynamic. Templates contain no business logic. Therefore, they only display data.
This architecture allows Django to solve various problems, which are discussed below successfully.
Inexperienced people consider Django to be one of the many content management systems (CMS). It is actually a software tool that you can use to build and run web applications.
Interestingly: The name of the framework emphasizes its versatility. It is named after renowned jazz guitarist Django Reinhardt. Although two fingers on his left hand did not function after an injury sustained in a fire, this musician played the guitar masterly. That is, the musician had to play chords with three fingers.
The Django framework handles a large number of tasks and increased workloads. It is used to create:
Django is also suitable for creating algorithmic generators, platforms for email newsletters, verification systems, filtering systems with dynamic rules and complex parameters, platforms for data analysis and complex calculations, and machine learning.
Django powers thousands of sites around the world. This framework is great for developing web applications. Let's see why web developers love this tool.
If you ask multiple developers why they chose Django, the answers are mostly the same. Below are the main advantages of the framework, thanks to which it became popular.
Experienced developers recommend thinking of Django as a system. This means that the framework is usually used with a lot of third party applications. They can be selected depending on the needs of a particular project.
To better understand this principle, imagine a Lego construction set. There are many standard blocks in it. Django has generic blocks too. For example, an authorization block or a newsletter subscription block is used in almost every project. Web applications created using the framework are composed of such independent blocks.
Django was introduced in 2005. Over the 15 years of its existence, it has changed and improved a lot. New features constantly appear in the framework, and old ones are being improved.
An important point: When you are unfamiliar with Django and are looking for an answer to a specific question, it is often straightforward. Thousands of specialists had already solved the same problems before you and shared their experience on the Internet. This is how the Django community works.
The Django admin panel is automatically generated when you create your application. This saves the developer from having to create the admin panel manually.
Using third-party applications, Django's default management console can be improved and adapted to suit your project's needs. Also, the framework allows you to customize the interface of the default admin panel.
The code written in Python is readable and understandable, even for untrained people. This is one of the factors that make Python web applications SEO friendly. Django generates semantic URLs. They are also called human-readable URLs or CNCs. Django applications easily implement other search engine optimization features.
Django's functionality is extended with plugins. These are software modules that allow you to add the desired function to the site quickly. The official catalog contains hundreds of plugins that make it easy to implement sitemap.xml on the site, manage access, connect the Stripe payment system, and so on. If necessary, you can disable or replace plugins to adapt the application to the project's current needs.
Popular programming languages have libraries that are convenient for solving special problems. In libraries, you can find ready-made solutions: functions, classes, configurations, and so on. These solutions expand the capabilities of the language and simplify the creation of applications.
Django supports the use of libraries when developing web applications. Popular libraries include:
Django implements an Object-Relational Mapping (ORM) that enables your application to interact with databases (DB). ORM automatically transfers data from a database, for example, PostgreSQL or MySQL, to objects that are used in the application code.
ORM accelerates the development of prototypes and finished web applications in Django. The Django developer does not even need to know the language that is used to interact with databases.
ORM also allows you to switch between databases with minimal code changes quickly. For example, you can use SQLite on a local server and then switch to MySQL on a production server. However, to minimize errors, it is better to use the same database during development and production.
Django has drawbacks like any tool. The main disadvantages of the framework are listed below.
Django's capabilities can be overkill for a small project. However, there are other frameworks in the Python ecosystem that can be used in such cases. For example, if you want to make a simple chat, it's better to use Flask.
The WebSocket protocol provides real-time communication between the server and the browser. Django does not support this functionality out of the box. But the problem can be solved with other tools like aiohttp.
Some Django modules, like ORMs or forms, are difficult to replace. Developers have to spend a lot of time changing the framework's internal structure and use alternative tools.
The behavior of some Django components is not always easy to control. For example, the administrative console is one such component. If you want to add something that is not part of the Django ecosystem, it can take a lot of effort and time.
In general, the advantages of Django with a margin overlap the disadvantages of this framework.
Using the following list of sites built with Django, we will analyze the main benefits of implementing this platform. Consider these sites not only as examples but also as an inspiration for what you can apply to your own projects.
The largest video hosting YouTube is part of Google, which uses Python and the Django framework in many of its projects. YouTube is also no exception, and this entire giant platform is written on this framework.
It was first built in PHP, but the rapid growth of the audience and the need to quickly implement new features led the team to join the Django community. And the choice was completely justified, since the audience's growth did not stop (fortunately for them), and new features appear very often (fortunately for us).
Google has been using Python in many of its products for a long time. They always saw this language's potential and tried to implement it as much and as often as possible. The company uses the Python language and the Django framework for its main project, Google Search.
One of the world's largest sites for data storage, or simply put, cloud storage. DropBox has created a new way of storing data: instead of a computer - on the cloud. You can access your files anywhere and from any device (when you're online, of course). The most famous and popular cloud storage application for documents, videos, graphics, etc. allows us to store, sync, and share almost anything using Python's power.
Python was used to build the backend and client software. This allowed the team to come up with a product relatively quickly. Using Django, developers were able to add a user history option, sync an account across devices, and, most importantly, add a file sharing option.
Instagram is one of the largest social networks in the world. It allows users to post their photos, like others, and delve into the lives of not only their friends but also various celebrities around the world. Instagram is a mobile application, but if we talk about its web version, then it is completely and entirely built on Python Django.
From the beginning, Instagram has used Python as its core technology in its tech stack. They have used multiple versions of Python and have now migrated to a dedicated Python 3.5.
Instagram handles huge amounts of data and user interactions (likes, posts, etc.). With Django, the Instagram team can handle all of this, in addition to capitalizing on ready-to-implement tools that allow them to focus on UI and UX.
This is what helped Kevin and Mike, the co-founders of Instagram, develop the first version of the app in about two weeks. According to Mike, it was very easy to get started with Django as it didn't require many solutions or a lot of customization, and it made testing easier.
Instagram began to grow rapidly, and the company began looking for new technologies for its system.
They considered different options, but in the end, they decided to get Python and Django to work on them on a large scale. Hui Ding, a former head of development at Instagram, says, “We were able to reach several hundred million users with our Python / Django stack, so we decided to continue. The important thing about the decision was that our engineers really love Python. This is actually the reason people want to work for us."
What's more, Instagram uses Sentry to monitor and report Python bugs. Sentry allows them to track and detect bugs on their system in real-time.
Reddit is the largest social news project. Users themselves can post various articles, as well as comment and vote for other articles of other authors. On this site, you will find thousands of Internet news and disputes on various topics. Most of the site's functionality is done in Python.
Pinterest is very similar to Instagram. Here users can also share various photos, but only those photos that meet their interests or their selection. For example, if a user leads Pin about the fastest cars, then by subscribing to him, you will receive a bunch of photos with fast cars.
Django is popular among social media platforms as it helps to deal with massive amounts of data and can handle thousands of user interactions every second. Pinterest has 250 million monthly active users, so you need to deliver great performance and scale while maintaining performance efficiently. With Django, Pinterest can handle this by allowing Pinterest users to follow each other, share boards, and pins.
Quora is an American website. On this portal, users can ask various questions, and other users can answer them. The more you answer the questions, the higher the rating you will have on the site. So, if you do not know the answer to something, then the easiest way to get an answer is to post it on this site.
In general, Yahoo uses the Node.js platform for its projects. However, they decided to use Python to create their maps. Yahoo Maps is an ordinary, good map that allows you to get a route from point A to point B. This search engine is not very popular in the eastern countries, but it is a very large and popular search engine in the West. Yahoo Maps are considered reliable, which is why many people use them on their daily travels.
Spotify is an app that lets you find, listen, and share music with your friends for free. The application is very convenient, as it allows you to find relevant music and add it to your playlist quickly.
Like iTunes, Spotify has changed the way people listen, share, and buy music. When using it, you can access your music library anywhere and on any device. The developers chose Django for two reasons:
With Django, they not only got the full set of Python features but also made the most of it.
However, in fact, Spotify uses a combination of Java, Python, and C ++, with the latter being used less than ever before.
The Onion is another great Django development example. This is a satirical newspaper that also has an online version of its source. All publications, design, and all functionality of their site is done in Python using Django.
Today it is one of the most famous and widely read newspapers in the world.
Disqus is one of the most significant projects ever done with Django. It allows you to implement comments and discussion options on your site, analyze audience activity, and customize ad serving.
Leveraging the Django framework allowed the team to not only build a website quickly but continue to scale it to millions of new users. The Disqus team is now using other frameworks as well, but Django continues to be the top choice thanks to its ever-growing community and many ready-to-implement options.
But Django was used by Disqus for more than just developing and scaling websites. The Disqus development team also used Django to build Sentry, an internal tool for tracking bugs, debugging, and fixing application crashes.
As we have already mentioned, Django was originally built to support a content application for Lawrence Journal-World. Currently, The Washington Post, The Guardian, The New York Times, and other newspaper sites that use Django are highly scalable and can handle the large amounts of data generated by their daily audience.
Launched back in 2008, this cloud-based Git repository has attracted millions of developers. With 17 million requests and 6 million repositories a year, this is one of the busiest Django-based web applications.
The BitBucket team decided to use Django for a couple of reasons. The first is thousands of developers in their community. The second reason we mentioned earlier is the set of ready-to-deploy Django solutions.
Another Django site is Eventbrite, a ticketing and event management platform. Originally built using Python and native frameworks, it later switched to Django to cope with the platform's rapid growth in audience and interaction volumes. Thanks to Django's scalability, Eventbrite, like many other websites built with Django, can adapt to any audience size and continually provide users with new updates.
One of the most popular browsers, Mozilla, has to handle hundreds of millions of requests every month. Given the number of requests they receive via the API, it's easy to see why the team decided to switch from PHP + CakePHP to Python + Django. The Mozilla support site and all add-ons for their browser are now powered by Django.
When you have a definite thought, it only takes a few minutes to transform it into the programming language and give it its real form using Django. The fact that Django is freely available makes it possible to significantly simplify the web development process since the developer can focus on the design process and development of the application's functionality. Thus, Django is the perfect tool for startups where web designers need to reflect the company's vision and goals.
