# Models

Not that

leaf MVC models extend the base model, so read Leaf MVC core docs (opens new window) for full functionality.

Eloquent

MVC Core models are powered by Laravel's eloquent engine so we recommend getting familiar with it (opens new window).

In leaf MVC, we don't really have anything to do with our models: Leaf Core has taken all the trouble out of using models, so all we have to do in leaf MVC is to generate the model and include it in our controller.

Our Models are kept in app/models, but we won't need to create our models manually. leaf MVC's command line tool covers this for us.

Commands

Model commands now rely on Aloe CLI instead of the standard Leaf CLI.

php leaf g:model <Name>
1

A new model will be created in the app\models directory which looks like this:

<?php
namespace App\Models;

class ClassName extends Model {

}

That's all we need to do with our model. leaf MVC's models have methods prepared which allow us to manipulate out database without doing much.

We can create, read, update and delete without writing any code to specially access our database.

# Using a model

As mentioned earlier, we include models in our controller to use them. We can do that by using the use keyword.

<?php
namespace App\Controllers;

// include the model
use App\Models\User;

class UserController extends Controller {
  public function index($id) {
    // use the model here
    $user = User::find($id);
    $this->respond($user);
  }
}

In our controller, we can do these:

// return all rows
ModelName::all();

// return all rows sorted by date created
ModelName::orderBy('created_at', 'desc')->get()

// find a database row by id
ModelName::find($id);

// find a database row by title
ModelName::where('title', 'Title goes here')->get();

// create a new database row
$model = new ModelName;
$model->field = $this->request->get("field");
$model->save();

// delete a post
$model = ModelName::find($id);
$model->delete();
