Question

我有这个型号：

class User < ActiveRecord::Base
  TYPE = {:admin => "Administrator", :owner => "Owner", :client => "Customer"}

  # some codes here
end

当我在rails console中运行以下代码时：

User::TYPE

输出：

{:admin => "Administrator", :owner => "owner", :client => "Customer"}

当我在控制器中添加代码时：

 User::TYPE

这是输出：

[
  {
    "user_types": {
      "user": "Administrator",
      "owner": "owner",
      "client": "Customer"
    }
  },
  {
    "user_types": {
      "user": "Administrator",
      "owner": "owner",
      "client": "Customer"
    }
  },
  {
    "user_types": {
      "user": "Administrator",
      "owner": "owner",
      "client": "Customer"
    }
  }
]

我只需要：

{
    "user_types": {
      "user": "Administrator",
      "owner": "owner",
      "client": "Customer"
    }

我在这里做错了什么。我也试过User::TYPE，但我没有得到正确的结果。

更新：

这是我的控制器代码：

def user_types
  @user_types = User::TYPE
end

在我看来显示结果时，我用rabl来展示json：

object @user_types => false

node(:user_types) {@user_types}

这是输出：

[
  {
    "user_types": {
      "user": "Administrator",
      "owner": "owner",
      "client": "Customer"
    }
  },
  {
    "user_types": {
      "user": "Administrator",
      "owner": "owner",
      "client": "Customer"
    }
  },
  {
    "user_types": {
      "user": "Administrator",
      "owner": "owner",
      "client": "Customer"
    }
  }
]

我只想这样输出：

 {
    "user_types": {
      "user": "Administrator",
      "owner": "owner",
      "client": "Customer"
    }
  }

Rabl正在映射@user_types。

在你的情况下，它应该是：

# xxxx.rabl
object false

node(:user_types) {@user_types}
