pest Laravel Livewire Plugin: date cast with format causes test failures

Eloquent model contains: a 'dateAttribute' => 'date:Y-m-d' cast.
All tests of this component fail during Livewire's hydration cascade (see below), but it continues to display properly via browser.
When changing the cast from date:Y-m-d to date, all tests pass, but <input type="date" wire:model="dateAttribute" ... > fails to bind the existing value.
[ADDED] Potentially complicated by the fact that the models use jenssegers/laravel-mongodb.

Since Livewire itself seems to handle all of this as expected, I believe the issue is somewhere within Pest's Livewire Plugin.

I have pasted the verbose Pest failure below.

Additional, possibly useful information: I do not know why it says $subject in the exception message. It is neither an attribute nor a relation of the model in question.

[UPDATED with MongoDB context since it now seems important.]

I was able to recreate this with the following setup:

Model:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Jenssegers\Mongodb\Eloquent\Model;

class DateFormattedModel extends Model
{
    use HasFactory;

    protected $connection = 'mongodb';
    protected $collection = 'datemodels';

    protected $casts = [
        'dateAttribute' => 'date:Y-m-d',
    ]
}

Component:

<?php

namespace App\Http\Livewire;

use App\Models\DateFormattedModel;
use Livewire\Component;

class DateFormat extends Component
{
    public DateFormattedModel $model;

    public function doNothing()
    {
        // literally doing nothing
    }

    public function render()
    {
        return view('livewire.date-format');
    }
}

Template:

<div>
    {{ $model->dateAttribute }}
</div>

Test:

<?php

use App\Http\Livewire\DateFormat;
use App\Models\DateFormattedModel;

it('can serialize a date', function () {
    $model = DateFormattedModel::factory()->create();

    $response = $this->livewire(DateFormat::class, ['model' => $model]) // does not fail here
        ->call('doNothing'); // fails here

    $response
        ->assertStatus(200);
});

I have narrowed this further to an interaction with the model factory.

<?php

namespace Database\Factories;

use Illuminate\Database\Eloquent\Factories\Factory;

class DateFormattedModelFactory extends Factory
{
    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition()
    {
        return [
            // 'dateAttribute' => $this->faker->dateTimeBetween('2022-07-03', '2022-07-05'), // fails
            // 'dateAttribute' => \Carbon\Carbon::parse('2022-07-04'), // fails
            'dateAttribute' => '2022-07-04', // succeeds
        ];
    }
}

Hi, please could you provide a small reproducible repository that we can use to test this? 🙂

Regarding the reason it shows $subject is the issue, it's because that's the 2nd parameter to the preg_match() function signature. 👍🏻

Maybe if I get to the end of a sprint with a whole bunch of spare time, sure.

Jul 22 '22 14:07 trip-somers

Just copied your code examples verbatim into a clean Laravel app, and was unable to reproduce.

No rush about the repro, I'll try and have a look into it if I get time. 👍🏻

Jul 22 '22 14:07 owenvoke

I will admit to trying my base case on an existing app instead of a fresh one, but the only other thing I can think of would be that the database is MongoDB and the models use the jenssegers/laravel-mongodb repo. I will mess around with it some more when I can.

For now, my work-around was to change the factory to use a string.

Jul 22 '22 14:07 trip-somers

Quick note to say that I have updated previous comments with MongoDB context.

Jul 22 '22 21:07 trip-somers

Thanks, I'll try and take a look soon using MongoDB. 👍🏻

Ok, I just pushed some changes to my repro repo, and can confirm that I can reproduce the issue you're getting. 👍🏻

I can exactly replicate this, for some reason (only using the MongoDB model), in render() the $this->model->dateAttribute is set to a \DateTime instance. Whereas in doNothing(), it's set to an empty array. For some reason, it seems to strip that after the page has been rendered. 🤔

This is not a Pest issue.
