如何允许数组 json 和 Rails？

Question

对于json

{
   "version":"1",
   "configs":[
      {
         "title":"Good",
         "body":"Body"
      },
      {
         "title":"Good",
         "body":"Body"
      }
   ]
}

如何在控制器中使用 Rails' params.permit 允许它？

我试过了

  params.permit(
    config_setting: [
      :version,
      configs: [
        :title,
        :body,
      ]
    ],
  )

但好像不对

目前您允许 json 具有以下结构：

{
   "config_setting": [
      {
         "version":"1",
         "configs":[
            {
               "title":"Good",
               "body":"Body"
            },
            {
               "title":"Good",
               "body":"Body"
            }
         ]
      }
   ]
}

只需将 config_setting 节点添加到数据或将强参数块调整为：

params.permit(
   :version,
   configs: [
     :title,
     :body,
   ] 
)
