主动资源抱怨期望哈希-Activeresourcecomplainingaboutexpectsanhash

I am using active resource to get data from an api and display it,
My controller model.rb has

我正在使用活动资源从api获取数据并显示它，我的控制器model.rb有

class Thr::Vol::Dom  '/vv/test/domains/2013-06-25T05:03Z')
    x
  end
end

When i call this Thr::Vol::Dom.find method it returns the following error:

当我调用此Thr :: Vol :: Dom.find方法时，它返回以下错误：

ArgumentError: expected an attributes Hash, 
  got ["0.0.0.0", "1.1.1.1", "2.2.2.2", "3.3.3.3", "4.4.4.4"]

The api is expected to feed something like this

预计api会提供类似这样的东西

{"abs.com":["0.0.0.0", "1.1.1.1", "2.2.2.2", "3.3.3.3", "4.4.4.4"]}

for the call i made.

我做的电话。

The API returns the correct hash but i guess active resource is not able to read it properly, it is directly reading the value in the key-value pair of the hash.

API返回正确的哈希值，但我认为活动资源无法正确读取它，它直接读取哈希值的键值对中的值。

I want to fix this "ArgumentError" error , i want to display the contents of the returned hash in the view.

我想解决这个“ArgumentError”错误，我想在视图中显示返回的哈希的内容。

2 个解决方案

class YourModel 

class JsonFormatter
  include ActiveResource::Formats::JsonFormat

  attr_reader :collection_name

  def initialize(collection_name)
    @collection_name = collection_name.to_s
  end

  def decode(json)
    remove_root(ActiveSupport::JSON.decode(json))
  end

  private

  def remove_root(data)
    if data.is_a?(Hash) && data[collection_name]
      data[collection_name]
    else
      data
    end
  end
end

require 'JSON'

hash = JSON.parse('{"abs.com":["0.0.0.0", "1.1.1.1", "2.2.2.2", "3.3.3.3", "4.4.4.4"]}')

hash["abs.com"] => ["0.0.0.0", "1.1.1.1", "2.2.2.2", "3.3.3.3", "4.4.4.4"]
