解决laravel-admin中select在form编辑时不能自动选中当前的值的问题

    /**
     * 获取用户列表-select-option
     * @return User[]|\Illuminate\Database\Eloquent\Collection
     */
    public static function getSelectOptions()
    {
        $options = DB::table('users')->select('id','name as text')->get();
        $selectOption = [];
        foreach ($options as $option){
            $selectOption[$option->id] = $option->text;
        }
        return $selectOption;
    }

    protected function form()
    {
        return Admin::form(Article::class, function (Form $form) {

            $form->display('id', 'ID');

            $form->text('title','标题')->rules('required|min:10');
            $form->textarea('description','摘要简介');
            $form->ueditor('body','正文')->rules('min:10');
            $form->select('user_id','作者')->options(User::getSelectOptions());
            (略)

$form->select('user_id','作者')->options(admin_base_path('/api/users'));
