As a high-level Python web framework, Django enables programmers to build a variety of modern web application with less and clean code. In addition to being highly scalable, it further comes with a number of useful features like ORM, forms and admin interface. As a Python Programmer, I am a big fan of Django and I strongly believe businesses should invest in Django. The web framework also provides a number of security features that help programs to protect the web applications from malware threats. But the developers still need to follow several best practices to build and deploy Django applications in a better and simpler way.

7 Django Development Best Practices Each Web Developer Must Know

1) Set up Persistent Database Connections
Django allows users to establish 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 persistent connection, each request will make connection 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
The default configuration allows you to take two standard template loaders. But each time a request is made each of the two templates 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 Cache
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 at regular intervals. But you still have 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 a request is made by the application. However, you still need to store the session data in the database for the longer run.

4) Keep the Application and Libraries Separate
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 myproject folder. The apps folder will contain models, views and similar components of the project application. At the same time, you can store all libraries and other components of the project in the libs folder. However, it is also important to import the apps and libraries to the Django project by writing the correct path.

5) Store All Templates in One Place
It is also important to store all templates and template tags in the same place. You can even consider creating a Django application to contain these templates and template tags of the project. However, you need to ensure that the Django app is stored in the myproject folder. Likewise, the app must be included file of the project.

6) Install HTML5 Boilerplate
You can always make the Django web application more responsive by using HTML5, CSS and JavaScript. You also have option to download and install HTML5 Boilerplate. The contents of the zip file need to be stored inside the templates folder. However, you must remember that the js and css folders are static. You also need to make changes to the index.html to make these folders link to the project.

7) Monitor and Control Processes using Supervisor
While deploying the Django application on UNIX, you have option to monitor and control the processes using Supervisor. But the tool will require you to create separate configuration file for each process. Once you create the configuration files, Supervisor will control all processes efficiently. It can further back up the processes, and use the backup to restore the processes in case of disruptions and interruptions.
