Best Practices in Django Development

As a high-level Python web framework, Django enables programmers to build various modern web applications with less and clean code. In addition to being highly scalable, it comes with several valuable features like ORM, forms, and an admin interface. As a Python Programmer, I am a big fan of Django, and I firmly believe businesses should invest in Django.

The web framework also provides several security features that help programs protect web applications from malware threats. But the developers still need to follow several best practices to build and deploy Django applications better and more straightforwardly.

7 Django Development Best Practices

1) Set up Persistent Database Connections in Django

Django allows users to establish a connection with the database in a number of ways. But you can always set up persistent connections while using PostgreSQL. When you do not set up the persistent connection, each request will connect to the server individually, and the server has to authenticate each user request.

The additional connection and authentication may result in memory leaks and poor user experience. Each persistent connection will remain alive for up to 10 minutes. Hence the chances of memory leaks are reduced drastically.

2) Turn Cached Loading on on Django

The default configuration allows you to take two standard template loaders. But each time a request is made, the two template loaders search the file system and parse the templates.

The process increases the response time per request. You can always turn the cached loading option in the configuration to enable Django to find and parse the required templates only once.

3) Store the Sessions in the Cache in Django

Django, by default, stores all user sessions in databases. So you have to execute SQL queries to retrieve the user session data from the database to obtain the required user object information.

Also, you must clean the old user sessions stored in the database regularly. But you still have the option to store the session data temporarily in Cache by enabling the Memcache option or using tools like Redis. When the session data are stored in Cache, the SQL query need not be executed each time the application makes a request. However, you still need to store the session data in the database for the longer run.

4) Keep the Application and Libraries Separate in Django

Django allows you to store the application and libraries in two distinct folders and use these folders as packages. So you can create two different folders inside the project folder. The “apps” directory will house models, views, and similar components of the project’s application.

At the same time, you can store all libraries and other components of the project in the libs folder. However, importing the apps and libraries to the Django project is also important to write the correct path.

5) Store All Templates in One Place

Storing all templates and template tags in the same place is also important. You can even consider creating a Django application to contain the project’s templates and template tags.

However, you must ensure the Django app is stored in the project folder. Likewise, the app must be included in the file of the project.

6) Install HTML5 Boilerplate in Django

You can always make the Django web application more responsive using HTML5, CSS, and JavaScript. You also have the option to download and install HTML5 Boilerplate.

The zip file’s contents need to be stored inside the templates folder. However, you must remember that the js and css folders are static. You must also make changes to the index.html to link these folders to the project.

7) Monitor and Control Processes using Supervisor in Django

While deploying the Django application on UNIX, you can monitor and control the processes using Supervisor. But the tool will require you to create a separate configuration file for each process.

Once the configuration files are established, Supervisor efficiently manages all processes. It can further back up the processes and use the backup to restore them in case of disruptions and interruptions.

Introduction to Django Development

Django represents a Python web framework at an elevated level, promoting swift development and an organized, practical approach to design. It follows the Model-View-Controller (MVC) architectural pattern and includes various built-in tools that help developers handle common web development tasks.

Setting Up a Virtual Environment in Django

Before starting a Django project, creating a virtual environment to isolate project dependencies is recommended. Virtual environments ensure that the dependencies of one project do not interfere with another, leading to a cleaner development environment.

Organizing Project Structure in Django

A well-organized project structure promotes maintainability and collaboration. Divide your project into distinct apps, each serving a specific purpose. This modular approach makes it easier to manage different components of your application.

Utilizing Django’s ORM for Database Interactions

Django’s Object-Relational Mapping (ORM) simplifies database interactions by allowing developers to work with database entities as Python objects. This abstraction streamlines database operations and helps prevent common security vulnerabilities like SQL injection.

Implementing User Authentication and Authorization in Django

User authentication and authorization are critical aspects of web applications. Django provides built-in authentication mechanisms that can be customized to suit your project’s needs. Always use these features to secure your application and protect user data.

Writing Effective Templates with Django’s Template Language

Django’s template language allows you to create dynamic HTML templates. Utilize template inheritance and built-in template tags to maintain consistent layouts across your application.
