As a Python web framework that works on the highest level, Django enables programmers to build a many differently kinds of modern web applications. These will uses less and encourages clean code. Not only this but it also features being highly scalable. It also comes with a number of different useful features such as ORM, forms as well as admin interface for applications. This web framework is able to provide many different security features. These enables programs built using Django to protect the web applications from the impending malware threats of any kind. But the coders and programmers or developers still need to follow many different best practices. And build as well as deploy Django applications in much simpler and better way.
7 Django Development Best Practices that Each Web Developer Must Note
1. Set up robust and Non-failing Database Connections
Django enables its users to create and use a connection with the database in a variety of different of ways. But you can always set up a strong and persistent connections when you use PostgreSQL. When you do not use the non failing or persistent connection. Each of the requests will make a connection to the server that is being used individually. And the server will need to authenticate the user request for each connection. This can cause many overheads. Such as for example additional connection and authentication can easily result in different kinds of memory leaks. This will lead to a poor user experience. Each of the used persistent connection is able to remain alive for 10 minutes. And because of this the chances of memory leaks are drastically reduced.
2. Turn Cached Loading on
The default configuration that Django uses allows developers to use two standard loaders for templates. But each time a request is created and made to each of the two templates loaders, it automatically will search the file system and will parse the configured templates. This process is bound to increases the response time that is used per request. Developers can always turn on and use the cached loading option by making changes in the configuration to tell Django to find and parse the required templates only once.
3. Store the Sessions in Cache
Django by its default nature stores all user sessions in the form of databases. So developers have to execute one or many SQL queries in order to retrieve the user session data from its respective database and obtain the required user object information for the user. Also, developers must clean the old user sessions that is already stored in the database, and this cleaning must happen at regular intervals. But as a developer you still have option to store the session data temporarily in the form of a cache by enabling the memcache option or with the help of tools like Redis. When the session data is being stored in cache, the SQL query can bypass the execution each time a request is created and made by the application. However, developers still need to store the session data into its respective database in the long run.
4. Keep the Application and Libraries Separate
Django allows developers to store the application as well as the libraries in two distinct folders and make use of these folders as packages. So developers can create two folders inside the myproject folder and use them. The apps folder will be used for containing models, views and other such similar components of the project application. At the same time, developers can store all libraries as well as other different components of the project in the libs folder. However, it is equally important to use and import the apps as well as its libraries to the root Django project by making use of the correct path in the code.
5. Store All Templates in One Place
As discussed in the above points, it is also important to store all templates as well as the template tags in the same place. You can also consider creating a Django application for containing these templates and template tags as a part of the project. However, you need to ensure that the Django app is being stored in the myproject folder. Likewise, the app should also be included settings.py file of the respective project.
6. Install HTML5 Boilerplate
7. Monitor and Control Processes using Supervisor
While deploying the respective Django application on UNIX, developers have option to monitor as well as control the processes using the help of a Supervisor. But the tool will require developers to create separate and independent configuration file for each of the processes. Once developers create the configuration files, the Supervisor will control all processes efficiently. It will also be able to further back up the processes, and use the backup in order to restore the processes in case of any kind of disruptions or interruptions.
