accessor for the date field

[schel4ok]

Do you have something like Carbon integrated in backpack?
Because when I try to add accessor for the date field it works well in my frontend, but backend ListOperation I got error

Carbon\Exceptions\InvalidFormatException
Could not parse '17 сентября 2026': Failed to parse time string (17 сентября 2026) at position 0 (1): Unexpected character

Problem appears only when I add following accessor im my model.

    public function getDateAttribute() {
        return Carbon::parse($value)->isoFormat('DD MMMM Y');
    }

But if I don't add it I have not beautiful date output in frontend like this 2026-07-22 00:00:00 instead of 17 сентября 2026.
I see that in backend date looks well, but I can't understand how it
So I want to know if you have some other method integrated in backpack, which I can use to output the date in frontend.

Backpack already handles date formatting for you in the ListOperation (the admin panel backend) using Carbon, and you do not need to override the accessor in your model to achieve a localized or formatted date display in the admin panel. In fact, overriding the accessor to return a formatted string (like Carbon::parse($value)->isoFormat('DD MMMM Y')) will break Backpack's date columns, because Backpack expects the raw date value (a Carbon instance or a date string), not a pre-formatted string. This is why you get the Carbon\Exceptions\InvalidFormatException—Backpack tries to parse your already-formatted string as a date, which fails.

How Backpack handles date formatting:

• In the admin panel (ListOperation), Backpack uses the date or datetime column types to display dates in a localized and nicely formatted way, using Carbon under the hood. You can customize the format using the format attribute in your column definition, and it uses ISO format parameters (not PHP's date() format) Docs: date column Docs: datetime column.
• You should not override the accessor to return a formatted string for the date attribute, as this will interfere with Backpack's internal formatting logic.

What you should do:

• Remove the custom accessor for getDateAttribute() that returns a formatted string.
• In your Backpack CRUD controller, define your column like this:

  $this->crud->addColumn([
      'name'  => 'date',
      'label' => 'Date',
      'type'  => 'date',
      // 'format' => 'DD MMMM Y', // Optional: customize format here
  ]);

• If you want a specific format, use the format attribute as shown above.

For your frontend (outside Backpack):

• If you want a pretty date in your frontend, you can use an accessor, but make sure it does not interfere with Backpack. For example, create a separate accessor (e.g., getDateForFrontendAttribute()) instead of overriding the main getDateAttribute().

Summary:
Backpack already integrates Carbon for date formatting in the admin panel. Do not override the main accessor to return a formatted string—let Backpack handle it via column definitions. For frontend formatting, use a separate accessor or format the date in your frontend code.
