In this section, we will explore the advanced features of
Django. 1) Practical
Software craftsmanship is a set of principles and practices that focus on creating high-quality software.
Django, this means building maintainable code, using the model-view-controller (MVC) architecture, and writing efficient tests. The goal is to create clean, reusable code that can withstand changes and updates.
Test Driven Development
Test Driven Development (TDD) is a software development methodology that values writing tests before code. This way of working ensures that the code produced meets the desired requirements in a systematic way.
It also automatically writes the tests for future reference.
Git branching is a technique used in software development to manage code changes. It allows developers to work on multiple versions of code at once, making the development process more efficient.
By using Git branching, developers can work on new features without interfering with the main codebase.
Upgrades are an essential part of software development. In
Django, it is vital to manage upgrades to ensure that users can use the latest features without any issues.
Django provides built-in tools for managing upgrades, making it easy to keep up with the latest version of the framework.
Graceful degradation is a software engineering principle that involves building applications that function even when certain components are unavailable.
Django provides mechanisms for handling errors and missing resources so that the site functions even when these resources are not present.
A membership site is a web application that restricts access to certain areas based on user authentication.
Django provides built-in mechanisms for managing user authentication, making it easy to build membership sites.
Bootstrap is a CSS front-end framework used to create responsive and mobile-first web applications.
Django provides integration with
Bootstrap 3, allowing developers to create visually appealing and responsive web applications more efficiently.
REST (Representational State Transfer) is a set of architectural principles for building web applications. In
REST is implemented using the
REST framework, which provides a set of tools for building
REST framework provides authentication and serialization capabilities, making it easy to build
Django provides integration with AngularJS, allowing developers to create scalable web applications more efficiently.
2) Best Practices for Developing Great Software
Writing Maintainable Code
Code maintains itself when it’s clean.
Django provides a framework for developing maintainable code.
Django’s built-in features, such as the ORM (Object Relational Mapping) system and the admin interface, make it easier to write clean, easy-to-understand code. Additionally,
Django provides best practices for structuring your code, such as the Model-View-Controller (MVC) architecture and URL routing.
Branching is an essential technique for managing code changes.
Django provides built-in tools for managing code changes, including versioning, conflict resolution, and merging.
These tools make it easier to keep track of code changes and maintain a stable codebase.
Djangular is a package that integrates
Django and AngularJS. It allows developers to build scalable web applications more efficiently by taking advantage of the strengths of both frameworks.
Angular Forms is a set of tools for building forms in AngularJS. With
Angular Forms, developers can easily create forms that validate user input and generate error messages.
MongoDB is a popular NoSQL database that provides a flexible and scalable data storage solution.
Django provides integration with
MongoDB, allowing developers to use this powerful database with
Django Admin interface provides a powerful tool for managing the backend of web applications. With the
One Admin feature, developers can customize the admin interface to fit their unique needs and make it easier to manage the application’s backend.
