Web development involves three core skills: Designing, Programming, and Problem solving – as it is chiefly concerned with web design, full stack development, and testing & debugging.
Hosting and maintenance are among its other, but non-core functions. As it is multi-skilled, the job of web developers can be demanding and challenging.
However, thanks to the introduction of “web frameworks,” which provide a foundation and tools for building web applications from scratch, it has become much more efficient and streamlined to develop robust and feature-rich web applications. Web frameworks are different from Content Management Systems (such as Wix, Weebly or WordPress). While the latter helps non-developers use a template to design and update content on websites, the former is meant for web developers to simplify and streamline the web development process using reusable components to reduce development time and effort.
The Django Advantage
Django is among the popular web frameworks for backend development. It is based on Python, one of the top web development languages. It can also be used for certain front-end development tasks. Its popularity has been growing since its release in 2005 as the framework is known for:
Rapid Development: Django’s design philosophy focuses on enabling fast and efficient development. It provides a wide range of pre-built features and libraries, allowing developers to quickly build web applications with less code.
Scalability and Versatility: Django is designed to handle high-traffic and complex web applications. It offers scalability features, such as caching, database connection pooling, and support for distributed architectures.
Cyber Security: Django incorporates various security features to help developers build secure web applications. The features include protection against common web vulnerabilities, such as cross-site scripting (XSS), cross-site request forgery (CSRF), and SQL injection attacks.
There are numerous success stories and case studies of applications built with Django across various domains, including websites, e-commerce platforms, content management systems, and more.
Hence, Django is considered a premium skill in the job market as the need for building such web applications is always on the rise. Consequently, Django training remains one of the choicest courses among students seeking to build a career in web development.
Django’s MVT architecture
Django has the backing of its own philosophy – or guidelines. It also has tools to help developers adhere to them.
The guidelines include: ‘Don’t Repeat Yourself’, which provides tools and conventions to promote code reuse and modular design; ‘Explicit is Better than Implicit’, which promotes clarity and readability by favoring explicitness in code, and ‘Security by Default’, which aims to provide secure defaults.
However, the core component that makes Django a capable tool for building scalable and maintainable web applications is its MVT architecture.
MVT is nothing but a set of high-level design templates, tools, and guidelines that simplify, streamline, and accelerate web development. This architectural pattern separates web applications into three components: the model, the view, and the template, wherein.
- Model represents the data and the business logic of the web application. The model component interacts with the database or other data sources to fetch and update data.
- View is responsible for presenting the user interface (UI) and rendering the data to the users. It represents the visual representation of the data and is responsible for displaying information and interacting with users.
- Template component represents the presentation layer and is responsible for defining how the data is rendered and displayed to users. The template system in Django combines the template with data to produce the final output.
Other key features of Django are: the provision for creating RESTful APIs, and Django’s intuitive admin interface.
Django has built-in features to create RESTful APIs, the APIs that follow the principles and constraints of Representational State Transfer (REST). RESTful APIs are essential for building scalable web services.
Django’s admin interface
The admin interface in Django is designed to provide a convenient and efficient way to manage application data without the need for extensive custom coding. It can save developers significant time and effort in building an administration panel, particularly for back-office or content management systems.
The interface can be extensively customised to match the look and feel of any particular application – developers can translate the interface into different languages and adapt it to regional preferences.
The interface also provides a comprehensive permission system for developers to control user access and restrict actions based on roles and permissions. It comes with a powerful filtering and search option.
In addition to these built-in features, Django also has the support of a large ecosystem of third-party packages that enable developers to make scalable web applications efficiently and rapidly.
