Solve the problem that select in laravel-admin cannot automatically select the current value when editing the form

This article mainly introduces how to solve the problem that select in laravel-admin cannot automatically select the current value when editing the form. It has a certain reference value. Now I share it with you. Friends in need can refer to it

Just create a method for each Model that can automatically generate a select option.

For example, create a method to generate options for the model User.php

    /**
     * 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;
    }

Use it in the corresponding controller, such as the controller of Article

    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)

Use as mentioned in the document The interface method, and the format in the returned document cannot automatically select the original value, it can only be blank.

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