What's inside this package?

UrlPresenter

The url presenter encapsulate the routes that are generated in Route::resource('users, UserController::class)

For one model

class UserUrlPresenter extends BaseUrlPresenter
{

    function getRouteName(): string
    {
        return 'users';
    }
}

// --- Examples ---

// Url presenter for routes that doesn't depend on a specific model (index, create)
$userUrlPresenter = new UserUrlPresenter();
$userUrlPresenter->index(); // --> /users
$userUrlPresenter->create(); // --> /users/create
$userUrlPresenter->store(); // --> /users (for post method)

// Url presenter for routes that depend on a specific model (show, edit, update, delete )
$user = User::first();
$userUrlPresenter = new UserUrlPresenter($user);
$userUrlPresenter->index(); // --> /users
$userUrlPresenter->show(); // --> /users/1
$userUrlPresenter->create(); // --> /users/create
$userUrlPresenter->store(); // --> /users (for post method)
$userUrlPresenter->edit(); // --> /users/1/edit
$userUrlPresenter->update(); // --> /users/1
$userUrlPresenter->destroy(); // --> /users/1

For related models

class UserPostCommentUrlPresenter extends BaseUrlPresenter
{

    function getRouteName(): string
    {
        return 'users.posts.comments';
    }
}

class Post extends \Illuminate\Database\Eloquent\Model
{

    public function getRouteKeyName(): string
    {
        return 'slug';
    }
}

// Example

$user = User::first();
$post = Post::first();
$comment = Comment::first();

$urlPresenter = new UserPostCommentUrlPresenter($user, $post, $comment);
$userUrlPresenter->index(); // --> /users/1/posts/the-post-slug/comments
$userUrlPresenter->show(); // --> /users/1/posts/the-post-slug/comments/1
$userUrlPresenter->create(); // --> /users/1/posts/the-post-slug/comments/create
$userUrlPresenter->store(); // --> /users/1/posts/the-post-slug/comments (for post method)
$userUrlPresenter->edit(); // --> /users/1/posts/the-post-slug/comments/1/edit
$userUrlPresenter->update(); // --> /users/1/posts/the-post-slug/comments/1
$userUrlPresenter->destroy(); // --> /users/1/posts/the-post-slug/comments/1

Entities

An entity is an extra layer that wraps your model to add extra logic. The BaseEntity only require a url() method to be implemented

class UserEntity extends BaseEntity
{

    public function url(): ?BaseUrlPresenter
    {
        return new UserUrlPresenter($this->model);
    }
    ... // more methods
}

// Example single model
$user = User::first();
$userEntity = new UserEntity($user);

$user->entity->getCreatedAtDayDateFormat(); // Sat, Oct 7, 2023

// Example multiple model
$users = User::all();
$userEntities = UserEntity::collection($users);

$userEntities->first()->url()->show() // /users/1

View Models

View models encapsulates all the logic and data that you need to send to your views.

IndexViewModel

This view model send to the view the following data:

• entities: A collection of the entities of the model defined in the IndexViewModel (i.e: UserEntity)
• pagination: Because now you receive a collection of entities and not models, this is the same as doing $users->links. now you can do:

  <div class="flex w-full mt-4 justify-end">
    {!! $pagination !!}
  </div>
  

• title:: This is just the string you return in the getTitle() method. It's useful in your index to add it in your blade like this:

    <h1 class="text-2xl">{{ $title }}</h1>

Example

class UserIndexViewModel extends BaseIndexViewModel
{
    public function getTitle(): string
    {
        return trans('Users');
    }

    public function getEntityClass(): string
    {
        return UserEntity::class;
    }
}


// In the UserController
class UserController extends Controller
{
    public function index(Request $request): View
    {
        $users = User::query()->with('roles');
    
        return view('users.index',
            (new UserIndexViewModel($users, $request))->build()
        );
    }
}

ShowViewModel

This view model send to the view the following data:

• entity: A single entity of the model defined in the ShowViewModel (i.e: UserEntity)

Example

class UserShowViewModel extends BaseShowViewModel
{
    public function getTitle(): string
    {
        return trans('User');
    }

    public function getEntityClass(): string
    {
        return UserEntity::class;
    }

    protected function getExtraData(): array
    {
        return [
            'title' => $this->getTitle()
        ];
    }
}

// In your UserController
class UserController extends Controller
{
    public function show(User $user)
    {
        $user->load('roles');
            
        return view('users.show', (new UserShowViewModel($user))->build());
    }
}

FormViewModel

This view model send to the view the following data:

• entity: A single entity of the model defined in the ShowViewModel (i.e: UserEntity)
• form: This contains the url for submitting the form, the method type (POST or PUT) and some other helper methods. It's useful to use it in your forms like this:

    <form method="POST" action="{{ $form->getUrl() }}">
        @csrf
        @method($form->getMethod())
    
    //...your fields

    <button class="btn btn-primary">
        @if($form->isEditType())
            {{ trans('Update') }}
        @else
            {{ trans('Create') }}
        @endif
    </button>
</form>

• title:: This will resolve automatically the title based on the method type. For example if you use ->setFormType(FormTypes::CREATE), the title will be Create user, if it's ->setFormType(FormTypes::EDIT), the title will be Edit User. You can use it like this:

    <h1 class="text-2xl">{{ $title }}</h1>

Example

class UserFormViewModel extends BaseFormViewModel
{

    protected function getEntityClass(): string
    {
        return UserEntity::class;
    }

    protected function getExtraData(): array
    {
        return [
            'roles' => Role::query()->get();
        ];
    }
}

// In your UserController

class UserController extends Controller
{

    public function create(): View
    {
        return view('users.form',
            (new UserFormViewModel(new User()))->setFormType(FormTypes::CREATE)->build()
        );
    }
    
    public function edit(User $user): View
    {
        return view('users.form',
            (new UserFormViewModel($user))->setFormType(FormTypes::EDIT)->build()
        );
    }
}

All ViewModel includes a method getExtraData() where you can return an array of extra data you need to send to the view.
