Test-driven development (TDD) is a software development process that relies on the repetition of a very short development cycle: requirements are turned into very specific test cases, then the code is improved so that the tests pass. This is opposed to software development that allows code to be added that is not proven to meet requirements.https://code.tutsplus.com/tutorials/beginning-test…https://rubikscode.net/2019/03/04/test-driven-deve…Linkedin Feel free to contact me.

Tip 1. Carefully handle user uploads If your web application allows users to upload files, you are opening yourself to an attack vector and the upload logic should, therefore, be handled carefully. It is important to validate all uploaded files to be sure they are what you expect (for instance, an image file and not a PHP script!) If your site accepts file uploads, it is strongly advised that you limit these uploads in your Web server configuration to a reasonable size in order to prevent denial of service (DOS) attacks.Recommendation: https://www.freecodecamp.org/news/complete-back-en…Sources:https://docs.djangoproject.com/en/3.0/topics/secur…https://owasp.org/www-project-top-ten/OWASP_Top_Te…https://snyk.io/blog/django-security-tips/Linkedin Feel free to contact me.

One of Django's main benefits is the built-in models and object-relational mapper (ORM). It provides a quick-to-use, common interface for data operations for your models and can handle most queries pretty easily. It can also do some tricky SQL once you understand the syntax. Django’s database layer provides various ways to help developers get the most out of their databases.https://docs.djangoproject.com/en/dev/ref/models/querysets/#django.db.models.query.QuerySet.prefetch_related https://concisecoder.io/2018/11/04/django-orm-optimization-tips/ https://medium.com/@hansonkd/performance-problems-in-the-django-orm-1f62b3d04785Linkedin Feel free to contact me.

What is Docker? How Does it Work and what’s the purpose? A container is a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another. A Docker container image is a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries, and settings.https://www.docker.com/Linkedin Feel free to contact me.

The Flask framework, like Django, is used to develop web applications. These two are the most popular Python web frameworks, and for good reason, they differ greatly in their philosophies.https://www.guru99.com/flask-vs-django.html#6https://www.quora.com/What-is-flask-framework-used-for-in-Python-How-is-it-different-from-Django-and-why-would-you-prefer-it-over-Djangohttps://testdriven.io/blog/django-vs-flask/Linkedin Feel free to contact me.
