Dependency injection

- [Instructor] One of Laravel's strongest features,…is it's Dependency Injection, or DI mechanism.…In the Laravel context,…DI merely means adding a class instance…to another class via it's constructor.…Let's see how painless it is to inject a dependency,…when we want to make a class available to our controller.…For the project, we will need a drop-down menu…with titles such as, Mister, Misses, et cetera.…We're going to use a model to obtain these titles.…

However, since it's a static catalog,…we really don't need to add a table to the database.…A simple way to go, is to create a model,…but not use any of the methods…that will fire any database actions.…Let's start by creating a title model with…php, artisan, make,…colon model, title.…Now let's open our title model,…and add an array of titles.…

Let's go, app, title.…Then we're going to add an array as protected,…titles, array,…equal to an array,…and inside of the array, Mister,…Misses, Miss, Doctor, and MX.…

We'll save, and now let's remove…the inheritant from eloquent.…
