Django may be a free and open-source Python web framework that helpfully solves common development challenges and allows you to build flexible, well-structured applications. Django features a lot of recent characteristics. The Admin, Object Relational Mapping tool (ORM), Routing, and Templating features made Django the best choice because applications require tons of labor and, while I enjoy my job the maximum amount as any developer could, I would like to spend as little time as possible on these basic repetitive tasks. Django allows you to try to do all this without compromising on flexibility.
1: Utilising System Python Environment for Project Dependencies
Don’t use Python’s global environment for project dependencies, since it can produce dependency conflicts. Python can’t use multiple package versions at an equivalent time. this will be a drag if different projects require different incompatible versions of an equivalent package.
This mistake is typically made by new Python and Django developers that don’t realize Python’s environment isolation features.
2: Not Pinning Project Dependencies during a [requirements.txt] File
A Python project should be able to start with a requirements.txt file and a standard replacement isolated environment. Normally you put in all packages through [pip/easy_install] but always remember to feature them to your [requirements.txt file] too. This makes it possible to deploy your project on servers, or for a team member to bootstrap the project on their own machine.
3: Performing on Old-style Python Functions rather than Class-based
Sometimes it’s an honest idea to use a little Python function in an application’s [views.py] file especially for tests or utility views, but generally, you ought to use class-based views (CBVs) in your applications.
4: Writing Fat Views and thin Models
Writing your application logic in views rather than models means you’ve written code that belongs in your model into the view, making it “fat” and your model “skinny.”
Break logic into small methods on your models. This enables you to employ it multiple times from multiple sources (admin interface UI, front-end UI, API endpoints, multiple views) during a few lines of code rather than copy-pasting plenty of code. So next time you’re sending a user an email, extend the model with an email function rather than scripting this logic in your controller.
5: A Huge, Unmanageable Settings File
Even the new Django project settings file features a lot of settings. In standard settings, the file grows ample, such as increasing up to 700+ lines of configuration, becoming difficult to take care of, especially when your dev, production, and staging environments all need custom configurations.
