Server-side validation is a technique where validation of data is done on the server. It is a way to improve the security of your application and keep your data safe.
Server-side validation is a software development process that runs on the server and validates data input by the client. It is beneficial because it helps to reduce the number of times a user has to validate data manually.
Django is a Python web framework that is used for creating web applications. Django has a built-in feature called server-side validation that ensures that the end user does not enter invalid data into the form fields. This feature validates the submitted data by comparing it with the form field's default value and if it doesn't match, Django throws an error message to the user.
