Description: Active Record Callback is a feature that allows triggering logic before or after certain events in models. These events can include creating, updating, or deleting records in a database. Callbacks are methods that automatically execute in response to these events, enabling developers to implement custom logic without directly modifying the program’s control flow. For example, they can be used to validate data, modify attributes before saving a record, or send notifications after deleting an object. Callbacks are a powerful tool in many web frameworks, as they promote separation of concerns and facilitate the management of business logic related to models. There are several types of callbacks, such as `before_save`, `after_create`, `before_destroy`, among others, each designed to execute at specific moments in an object’s lifecycle. This functionality not only improves code readability but also allows developers to maintain finer control over their applications’ behavior, ensuring that certain conditions are met or necessary actions are taken at key moments.<\/p>\n","protected":false},"excerpt":{"rendered":"
