西佛尼FOSRest ChoiceType

Question

我正在尝试用FOSRest提交一份表格。到目前为止还不错，但是我只想知道choiceType接受哪种格式？它是一个关联数组吗？还是..？

FormType

/**
 * {@inheritdoc}
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('name', TextType::class);
    $builder->add('roles', ChoiceType::class, [
        'multiple' => true,
        'expanded' => true
    ]);
}

提交的数据：

{"group":{"name":"esdfgh","roles":["ROLE_VIEW_ALL_CATEGORIES","ROLE_ADD_RECEIPTS","ROLE_EDIT_RECEIPTS","ROLE_VIEW_ALL_RECEIPTS"]}}

但这会导致错误：“此值在ChoiceType上无效”。

Answer 1

您需要提供有效的选择

选项是一个数组，其中数组键是项的标签，数组值是项的值

根据您的例子，应该是这样的：

/**
 * {@inheritdoc}
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('name', TextType::class);
    $builder->add('roles', ChoiceType::class, [
        'choices' => [
         "ROLE_VIEW_ALL_CATEGORIES" => "ROLE_VIEW_ALL_CATEGORIES",
         "ROLE_ADD_RECEIPTS" => "ROLE_ADD_RECEIPTS"
        ]
        'multiple' => true,
        'expanded' => true
    ]);
}
