How to change the format of all dates in Laravel8 project

@irslan define accesor for attribute.

<?php
 
namespace App\Models;
 
use Illuminate\Database\Eloquent\Casts\Attribute;
use Illuminate\Database\Eloquent\Model;
 
class User extends Model
{
    /**
     * Get the user's birth date.
     *
     * @return \Illuminate\Database\Eloquent\Casts\Attribute
     */
    protected function birthDate(): Attribute
    {
        return Attribute::make(
            get: fn ($value) => $value->format('d-m-Y'), //you need to cast date as carbon instance
        );
    }
}

You can use carbon to display (format) the date for display, but store in database YYYY-MM-DD.

@irslan if dates defined as dates in eloqent model and they use explicit format in blade, like

$model->created_at->format('Y-m-d')

you need to change it. You can search by code and replace all occurences

or explain how they display it

Thanks everyone. I define this function:

public function getDateAttribute($value) { return date('d-m-Y',strtotime($value)); }

I changed this:

to

{{ __('custom.date') }}: {{$invoice->date}}

It worked. Thanks
