Django is a free open-source framework that allows you to create web applications. It is written in popular Python. Current version of Django allows separating the visual presentation of an application from the business logic of the application.
What is the Django framework?
Django is a framework written in Python that allows you to build websites and applications. It has been developed since 2005 as a free and open source software. It works on the MVT (Model-View-Template) model. In a nutshell, the Model is the layer that handles the database. Template, on the other hand, is meant to display the UI and data. View interacts with the model and is responsible for the business logic.
What does Django provide?
Django allows you to build large apps that use complex databases in a simple and transparent way. The rapid development methodology is used for this. A huge number of ready-made components and extensions allow you to create complex sites. Due to the fact that Django is written in Python, it is simple to understand for many people, as Python is considered one of the easiest programming languages to learn. The fact that its solutions are used by YouTube and Spotify is a testament to Django’s wide range of applications. According to the estimates, several thousand programmers work on the development of the framework all over the world. Thanks to that it is constantly being improved, and bugs are eliminated very quickly. The best solutions are constantly developed and receive updates very often.
Why do developers love working with Django?
Apart from the aforementioned huge number of users constantly developing the Django framework, it is very useful and this is the reason why it is so popular among developers. Building an application is like putting blocks together to create a large and cohesive building. The main uses of Django undoubtedly include using it as a CMS (content management system). However, the possibilities are much wider and allow even to create standalone web applications. As an example, it can be used in communication platforms for document management or data analysis. You can also use it to create semantic addresses or entire ecosystems.
DRY in Django
One of the most important features that Django framework offers is DRY (Don’t Repeat Yourself). There is no repetition in the code development process. If a piece of code is already in the program we don’t write it again, but we call it. Thanks to this the programming process becomes faster and the code is much clearer. It is then easier to analyze and check, both by the programmer and testers. This saves a lot of time and allows us to develop and improve applications faster.
As mentioned before, thousands of people around the world are working on the framework. Therefore, it has very clear and extensive documentation. Thanks to Python, it has a very smooth learning curve. From the very beginning, we can create simple applications and extend them according to our needs. Answers to all questions can be found in documentation or on special user forums.
For which projects Django is perfect?
One of the most popular uses of Django is undoubtedly creating cross-platform applications, that is applications that should work on different types of devices and on different operating systems. It’s also perfect in places where scalability of solutions is in the first place. That is why many startups use it from the very beginning. Further expansion of the application is simple and does not involve huge costs. Other places where you should consider introducing Django are applications that offer users multiple roles. It will also be perfect for financial and e-commerce platforms. Social networks and corporate or SaaS applications can also be an interesting application.
