[Feature Request] $user->getChanges(), date transformation not being applied

[masterbater]

 $validatedData = $request->validated();
        $update = $user->update($validatedData);

        return response()->json(['message' => 'success', 'data' => $user->getChanges()], Response::HTTP_OK);

This returns

{"message":"success","data":{"fname":"fname","updatedAt":{"$date":{"$numberLong":"1727594198505"}}}}

I didnt test with default timestamp fields since I have custom fields, but the transformation should work especially with eloquent. Let me const CREATED_AT = 'createdAt'; const UPDATED_AT = 'updatedAt';

I understand that you expect the field updatedAt to be automatically updated when you call $model->update($data). This field is correctly updated, as proved by this passing test:

    public function testGetChange()
    {
        $user = User::create(['name' => 'John Doe']);
        $user->update(['name' => 'Jane Doe']);
        $this->assertSame(['name', 'updated_at'], array_keys($user->getChanges()));
    }

The call stack to update the timestamp when $user->update() is called:

HasTimestamps.php:64, Illuminate\Database\Eloquent\Model->updateTimestamps()
Model.php:1229, Illuminate\Database\Eloquent\Model->performUpdate()
Model.php:1155, Illuminate\Database\Eloquent\Model->save()
DocumentModel.php:738, MongoDB\Laravel\Tests\Models\User->save()
Model.php:1013, Illuminate\Database\Eloquent\Model->update()

If you freeze the time for testing, using Date::setTestNow(), then updated_at is updated with the non-different value. So $model->getChange() does not detect change on this field.

This is the same behavior with an SQL database. If you think this behavior is problematic, please submit an issue to Laravel.

Yes you are right about saving part, but my question is why date transformation or should I say the format of date return by getChanged() doesnt automatically return date or carbon date format. It returns the native date format by mongodb $numberLong

[masterbater]

If by default getChanges returns native database changes and doesnt respect your eloquent model casting and attributes mutators then Im wrong here thanks for giving the attention
