Model Object weird result

I have this model:

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

  # some codes here
end

When I run below code in rails console:

User::TYPE

Output:

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

And when I add the code in controller:

 User::TYPE

This is the output:

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

And I only I need:

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

What I am doing wrong here. I also tried User::TYPE but I don't get the correct result.
