Sometimes you may want to standardize the data before saving it to the database. For example, downcasing emails, removing any leading and trailing whitespaces, and so on.

A value object is a type of object that represents a value in a program, such as a point in 2D space or a date. The main advantage of value objects is that they are easy to understand, simple to use, and can improve the readability and maintainability of code. The proposal to add Data class was accepted by Matz on the Ruby forum here. How does it work?Using the newly defined class Data we can create a simple immutable

What is ReDoS? Regular expression Denial of Service (ReDoS) is a security vulnerability that can occur in a regular expression (regex) when the regex is applied to a long string. This attack is designed to make a system or network unavailable to its intended users. An example occurrence of a ReDoS Imagine that a website has a form that accepts user input and uses a regex to validate the input. The regex is designed to only allow alphanumeric characters in the input, so it looks like this: /^[a-zA-Z0-9]+$/. An attacker could potentially craft a string of input that consists of

In the era of content consumption where streaming platforms like YouTube and Netflix have millions of concurrent users, no one wants to wait more than a minute to consume anything, it must be available instantly! Streaming becomes a need in this situation. While downloading requires waiting until the entire file has been downloaded on your computer, streaming allows you to view downloaded portions of the material on the fly. This significantly reduces the waiting time. Let's see with the help of a small example how streaming was handled before Rails 7 and what changed after Rails 7. With Rails <

Rails 7.1 adds the raise_on_assign_to_attr_readonly config to config.active_record that is used to raise ActiveRecord::ReadonlyAttributeError error on assignment to attr_readonly attributes. The previous behavior would allow assignment but silently not persist changes to the database. Configuring config.active_record.raise_on_assign_to_attr_readonly In a newly created Rails 7.1 application, config.load_defaults 7.1 is set by default in application.rb. The default value of raise_on_assign_to_attr_readonly for config.load_defaults 7.1 is true and for config.load_defaults < 7.1

The query_constraints config introduced in Rails 7.1 is helpful for pre-setting the DB query constraints on the ActiveRecord models.
