Since this is example code for a tutorial, I'm guessing you might be trying to keep the code matching what you did in the cast. However, if you are open to improvements, I'd love to submit a pull request for some or all of these features:

1. If the presenter can't match the property requested to a property on the model, it should see if a snake case version of the property is available. $post->present()->createdAt would return $post->created_at. This allows us to use snake case in our database, but keep camel case in our view.
2. Throw an exception if you try to access a property that is not a presenter method or a model property. Currently it just returns an empty string, which I don't think is the expected response.
3. Allow the user to omit the () in ->present(). i.e. $post->present->created_at.

Hi ! Thanks for this package.

I have difficulties in using the presenters with an eloquent relationship.

Let me explain, when, for example I retrieve users and their profiles in this way:

Route::get('/', function() {
    $users = MyProject\Entities\User::take(10)->with('profile')->get();

    foreach ($users as $user) {
        echo $user->profile()->present()->fullName;
    }
});

I got an error: Call to undefined method Illuminate\Database\Query\Builder::present()

Am I missing something ?

Thanks !

This is my Presenter

if($this->status == 'pending'){ 
     echo '<span class="label label-teal"><span class="ico-file"></span> PENDING</span>';
}

i can call others column like
$this->id
$this->employee_id

but when i called $this->status it give me an error

ErrorException (E_UNKNOWN) 
Undefined property: RequisitionPresenter::$status 

this is my table

                        $table->increments('id'); 
            $table->integer('employee_id');  
            $table->timestamps();
            $table->integer('created_by');
            $table->integer('updated_by'); 
            $table->string('status')->default('pending');
            $table->datetime('status_at');
            $table->integer('status_by');
            $table->text('status_notes'); 

Please. :)

My Model :

<?php

namespace App\Models;
use App\Presenters\InventoryOutProductPresenter;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Laracasts\Presenter\PresentableTrait;

class InventoryOutProduct extends Model 
{
    use HasFactory,PresentableTrait;
    protected $presenter = InventoryOutProductPresenter::class;
   
}

My Presenter :

<?php
namespace App\Presenters;
use Laracasts\Presenter\Presenter;

class InventoryOutProductPresenter extends Presenter {

    public function product_text_format()
    {
        return $this->title.'('.$this->price_per_qty.')';
    }

}

Call : $model->present()->product_text_format;

I am attempting to use the Laracasts Presenter with the lists() method like so:

$physicians = Employee::physician()->get()->lists(<formattedName>, 'id');
// <formattedName> would be the column name of the employee's name.
// Since it is stored as first and last separately, I use the Laracasts Presenter to present the concatenated full name.

I have a namespaced Employee model, and a query scope to filter the query results. My issue is, without calling the present() method, I can't access my presenter method for formatting the name. I can not find a place to insert the present() method that makes the lists() method work properly. Has anyone done this before?

My current workaround was setting a custom getter on the model to get the concatenated full name that way, but I would like to use the presenter method I already wrote if that is possible.

With many other presenter packages out there, I keep coming back to this one for its simplicity and flexibility (others seem to limit themselves to much more restricted use-cases).

Anyway, tried adding a service to a presenter constructor, since the service contains functionality used across a number of the presenter methods:

public function __construct($entity, protected OrderService $orderService)
{
    parent::__construct($entity);
}

This did not work, as the additional parameter was not being set in PresentableTrait:

$this->presenterInstance = new $this->presenter($this);

So this tried this in PresentableTrait instead, and it worked a treat:

$this->presenterInstance = app()->make($this->presenter, ['entity' => $this]); 

Now my order presenter class has $this->orderService at its disposal.

Now, I know I can extend the trait with this fix (or something similar - this is first draft to check viability) for myself, but is this something that could be useful for this package? It should be possible for it to work across all the supported Laravel versions.

Having to include $entity to pass up to the parent is, unfortunately, a little messy.

Hey,

Will there be support for Laravel 6?

Why don't we rather use Traits for this?

Than we could have multiple "prester-traits" and it would still be nicely clean.

And it is very annoying to keep writing $model->present()->something.

I have

composer.json

"autoload": {
        "psr-4": {
            "BMTracking\\": "app/BMTracking"
        }
    }

/app/BMTracking/Entities/Question.php

<?php namespace BMTracking\Entities;

use Laracasts\Presenter\PresentableTrait;

class Question extends \Eloquent {

    use PresentableTrait;

   /**
     * @var string
     */
    protected $presenter = 'BMTracking\Preseters\QuestionPresenter';

/app/BMTracking/Presenters/QuestionPresenter.php

<?php namespace BMTracking\Presenters;

use Laracasts\Presenter\Presenter;

class QuestionPresenter extends Presenter {

    public function company()
    {
        return $this->company->name;
    }

    public function group()
    {
        return $this->groups{$this->entity->for};
    }

    public function frequency()
    {
        return $this->frequencies{$this->entity->frequency};
    }

    public function type()
    {
        return $this->types{$this->entity->type};
    }

}

And I receive

Please set the $presenter property to your presenter path. (View: /app/views/questions/index.blade.php)

The view is a simple foreach

@foreach ($questions as $question)
            <tr>
                <td>{{ $question->text }}</td>
                <td>{{ $question->present()->company }}</td>
                <td>{{ $question->present()->group }}</td>
                <td>{{ $question->present()->for_id }}</td>
                <td>{{ $question->sort }}</td>
                <td>{{ $question->active }}</td>
                <td>{{ $question->present()->frequency }}</td>
                <td>{{ $question->present()->type }}</td>
            </tr>
        @endforeach

Whant am I doing wrong? How can I track if the presenter class is loaded?

It seems like something has changed with Laravel 5.

Currently I'm not able to use a function name which is equal to the name of the property.
So this is not working and I can't figure it out why

public function description()
{
    return $this->description;
}

This will throw an Undefined property: App\Presenter\ApplicationPresenter::$description

The only way I could get this to work is by using a different method name

public function getDescription()
{
    return $this->description;
}

or referencing the property like this

public function description()
{
    return $this->entity->description;
}

Am I doing something wrong or is this a bug in interaction with Laravel 5 ?

I create

use Laracasts\Presenter\Presenter;

class StaffPresenter extends Presenter
{
    public function dob()
    {
        return $this->dob;
    }

}

I get error, but when i change method name it is ok.
I think that, it could do

https://packagist.org/packages/laracasts/presenter
Larvel 9.0 is not supported

Hi there ,first big thanx for this super easy/handy package.

i currently have something like

public function Creation_time() {
    return $this->created_at->diffForHumans();
}

which works great but once i use

$posts = Post::remember('all', 60)->paginate(12);

i get this error

Call to a member function diffForHumans() on null

which i think its because am no longer making a request to the server so now the $this doesn't refer to anything + the result is within a key all (which is made so i can clear the Cache in case of new data),

so how can i make the presenter work with the above ?

I create Presenters folder in workbench..., and then i create StaffPresent and pull it to StaffModel via docs help.
But when i call ->present()->....., it show error
Please set the $presenter property to your presenter path.

I couldn't get this working, until I realized that my presenter classes were not loaded. Added this to app/start/global.php:

ClassLoader::addDirectories(array(
....
  app_path().'/presenters',
));

Maybe this should be mentioned in the readme file?

I think the installation instructions for the Laravel 5 compatible versions need to change to reference 0.2.*
"laracasts/presenter": "0.2.*"

Hi guys,
i'd would ask if it's possibile to use presenter model inside the email blade template.
I said that because i'm trying to use it but i've an error

I wonder if this package is compatible with Laravel 5.2?

I say that because a long time is not updated and there are some changes that need to be done.

Hi guys i don't know why but if inside the presenter class i try to access like a method on relationship model

$this->relations()->count()

i get an error message on method 'Call to undefined method'. Why ?

For some reason I am unable to have model attributes the same name as a presenter method.

class AuthorPresenter extends Presenter
{
    /**

     * is not set.
     *
     * @return string
     */
    public function pen_name()
    {
        if ($this->pen_name) {
            return $this->pen_name;
        }

        return $this->user->name;
    }
}

View Snippet

<div class="author">by {{ $book->author->present()->pen_name() }}</div>

Error Returned

Undefined property: AuthorPresenter::$pen_name

In my presenter, to access the wrapped object's attribute I had to do it like:

In the example you are just doing $this->attr.. but it throws an exception because the attribute doesnt exist in $this, but in $this->entity

Could you please add support for Laravel 9?

Is there a way to get autocomplete for methods of Presenters in PHPStorm ?

Hello,

Love this package! Trouble is, it is annoying to pull in.

I have a blank Laravel app installed but I have to change my minimum-stability in my composer.json file to pull this package in as a dependency.

Problem with that is, it changes my Laravel version to the bleeding-edge version...

Can't I use the stable version of Laravel with this package?

I could imagine the present() method of the PresentableTrait accepting a parameter specifying the Presenter I want to use. I might have different Presenters for each Model for Ajax, Forms, Backend, Frontend etc.

Thoughts?

I have an Owner Model and an OwnerPresenter class. 'Standard' functionality os working fine. I am now trying to do something in a presenter part of which I will use in other presenters (but not all) so would like to utilise DI using a constructor in my Presenter Class. I get the following error:

Argument 1 passed to Owners\OwnerPresenter::__construct() must be an instance of Utilities\AddressBuilder, instance of Owners\Owner given, called in /home/vagrant/project1/vendor/laracasts/presenter/src/Laracasts/Presenter/PresentableTrait.php on line 29 and defined (View: /home/vagrant/project1/app/views/search.blade.php)

I have tried adding parent::_construct and parent::_construct($this->entity) but I am getting the same error.

I can see that there is a conflict with the constructors but struggling to work out how to solve it

I tried to do the following within my presenter:

    public function rating_value()
    {
        return $this->ratings()->avg('rating');
    }

But I kept getting the error

Call to undefined method Ideadrop\Presenters\IdeaPresenter::ratings()

Anybody shed any light?

Hi,

I'm trying to do something like

$post->present()->created_at

I have a created_at function in my presenter class. But somehow it doesn't work. It works if I named my created_at as createdAt though.
