Translating a KeyValue field

[grantholle]

I have a translatable Laravel\Nova\Fields\KeyValue field called options. I can get it to work by doing some interesting things with a custom attribute for the model:

public function options(): Attribute
{
    return new Attribute(function ($value) {
        while (is_string($value)) {
            $value = json_decode($value, true);
        }

        return $value;
    }, function ($value) {
        return json_decode($value);
    });
}

However, the key order of the keys get changed (sorted) after saving it. When I change the json_decode to be an array in the setter, it saves the column with nested/recursive locales and tries to save the keys of that field as columns in the database.

public function options(): Attribute
{
    return new Attribute(function ($value) {
        while (is_string($value)) {
            $value = json_decode($value, true);
        }

        return $value;
    }, function ($value) {
        // Returning an associative array instead
        return json_decode($value, true);
    });
}

Here is the error that happens when trying to save, "Undefined column: 7 ERROR: column "either" of relation "form_fields" does not exist":

update "form_fields"
set
  "options" = '{"en":"{\"en\": {\"apple\": \"ap\", \"either\": \"Either\", \"full-time\": \"Full-time\", \"part-time\": \"Part-time\"}, \"zh-CN\": {\"some\": \"x\", \"grape\": \"a\", \"part-time\": \"\u517c\u804c\"}}","zh-CN":"{\"en\":\"{\\\"en\\\": {\\\"apple\\\": \\\"ap\\\", \\\"either\\\": \\\"Either\\\", \\\"full-time\\\": \\\"Full-time\\\", \\\"part-time\\\": \\\"Part-time\\\"}, \\\"zh-CN\\\": {\\\"some\\\": \\\"x\\\", \\\"grape\\\": \\\"a\\\", \\\"part-time\\\": \\\"\\u517c\\u804c\\\"}}\",\"zh-CN\":{\"some\":\"x\",\"grape\":\"a\",\"part-time\":\"\\u517c\\u804c\"}}"}',
  "either" = 'either',
  "full time" = 'Full-time',
  "part time" = 'Part-time',
  "some" = 'x',
  "grape" = 'a',
  "part-time" = '兼职',
  "updated_at" = '2024-02-06 17:07:41'
where
  "id" = 18

The order of options is kind of important, but I can't figure out how to get it to work. I may not have a choice.
