Using protected $dateFormat throws trailing error - laravel

Question

I am trying to format the date at the model using:
protected $dateFormat = "Y-m-d";
and I am getting this error:
"The separation symbol could not be found Trailing data" on line 582 of C:\wamp64\www\israplanet.com\vendor\nesbot\carbon\src\Carbon\Carbon.php
Using
protected $dateFormat = "Y";
causes this error:
"Trailing data" on line 582 of C:\wamp64\www\israplanet.com\vendor\nesbot\carbon\src\Carbon\Carbon.php
This example is from the October docs.
Whats is wrong here?

Answer 1

I'm not familiar with the example you have given (ie: using protected $dateFormat = "Y-m-d";) but when I do something like this I tend to use an accessor on the model:
public function getFormattedDateAttribute($value)
{
return $this->created_at->format('Y-m-d');
}
Obviously created_at would need to be replaced with the name of the date field. You'd then be able to access it in Twig as {{ array.formatted_date }}.

Answer 2

I cannot name this as good answer, but for now i at least can continue.
I simply changed format of the columns (created_at and updated_at) to date format and it stores the way i wanted it, but i always trying to fix problems (this habbit takes a lot of my time).
another option is to use handlebar helper for this.
But i want to understand the problem in the root.
(btw - thanks for answers)
