Most web apps have the concept of an "administrator." Administrators are typically users with elevated permissions and access to restricted areas of the application. For example, imagine you want to retrieve all authors that have books titles start with PHP. This is commonly referred to as “Single Table Inheritance,” but I prefer to just call it “Model Inheritance”. When retrieving model records, you may wish to limit your results based on the existence of a relationship. In this case, I can just load all the records using the function I had created in the Parent model and pass them to the blade templates using the compact(). By extending another model, you inherit the full functionality of the parent model, while retaining the ability to add custom methods, scopes, event listeners, etc. This technique involves creating new Eloquent models that extend other models. The demo consists of a single page application that shows a list of links or bookmarks. Let’s explore another alternative that can be used as a stand-in for repetitive where statements and local scopes. To practice the examples explained throughout the series, you’ll download a setup to run a PHP development environment on containers. There are many times when it’s necessary to do computations or add extra attributes based on existing attributes on an eloquent model. For more advanced users, features like scopes, accessors, and mutators offer more expressive alternatives to the query-building patterns of old. This article will explain the different ways to automatically manipulate and mutate eloquent model attributes while accessing or retrieving them. When starting out with Eloquent, it’s natural to reach for familiar operations like where and join. Tools like Laravel’s Eloquent ORM allow us to interact with databases at a higher level, freeing us from lower level details like query syntax and security. So, for example, for a text input named email, the user models email attribute would be set as the value. We’ve come a long way since the days of hand-writing SQL queries in our web apps.
