Before we move on, let's talk about CRUD. Do you

know what that acronym stands for?

It stands for create, read, update, and delete.

These are the four basic operations for working with a resource.

In our application, we have a blog post resource, and we

want to allow users to create new posts.

Also, we need to provide a way to read them, in other words,

to show the information about a specific post.

And we also want to allow users to update them and delete them.

This pattern is so common that frameworks like Laravel

provide a lot of functionality to manage these operations

in a predictable and uniform way.

For example,

Laravel provides us with a special type of controller

known as a resource controller.

This resource controller assumes that you will implement

CRUD operations on a specific resource.

So unlike the regular controller, it will be prepopulated with certain actions.

And here are the names of these actions that will be provided by default. Create

and store should sound familiar because that is exactly how we named our two

routes for creating and storing a new post resource.

So the create action should serve a form for creating a new resource, and store

action should actually store that resource in the database.

The show action should read the information from the database about a particular

resource instance and show it to the user. Edit and update are similar to create

and store, but the edit action serves the form for modifying an existing

resource instance and update is used for updating information about that

instance. Destroy is self‑explanatory.

It is used for deleting a specific instance of the resource from the

database. So these actions round up all of the CRUD operations.

This only leaves us with the index section,

which is usually used to present all of the

instances from that specific resource.

So if the resource in question is a blog post,

this action should show a list of all blog posts from the database.

In the next lesson,

we will implement this resource controller in our own application.
