如何在Sanity Studio中设置无线电按钮的默认值？

Question

我正在尝试在Sanity Studio中设置默认值列表。

代码：

export default {
  name: 'banner',
  title: 'Banner',
  type: 'document',
  fields: [
    {
      name: "category",
      title: "Category",
      description: "Choose a category",
      type: "string",
      options: {
        layout: "radio",
        list: [
          { title: "Documentary", value: "documentary" },
          { title: "Fiction", value: "fiction" },
        ],
      },
      // set initial value here ?
    },
  ]
}

有一个称为initialValue的属性，可以轻松设置字符串的默认值，但是我不知道如何使用无线电项目来完成此操作。

如何将无线电项目Fiction在加载页面时已选择？

          { title: "Fiction", value: "fiction" },
        ],
      },
      initialValue: "documentary", // set initialValue's value to one of the `value`s in your list of radio items
    },
  ]
}```

尝试直接在文档对象上而不是在字段上使用initialValue：

export default {
  name: 'banner',
  title: 'Banner',
  type: 'document',
  fields: [
    {
      name: "category",
      title: "Category",
      description: "Choose a category",
      type: "string",
      options: {
        layout: "radio",
        list: [
          { title: "Documentary", value: "documentary" },
          { title: "Fiction", value: "fiction" },
        ],
      },
    },
  ],
  initialValue: {
    category: 'fiction'
  }
}
