Ruby on rails 3 解析生成的JSON时出现问题

我得到了一个通过Rails3（通过API）生成的JSON对象。我需要在它周围放置一个命名的标签，或者松开第一个“层”。我知道这听起来很奇怪，但我不能在客户端循环它

<% @array['email'].each do |item| %>

    <%= item['value_1'] %>

<% end %>

这是解析代码：

@results = RestClient.get "http://localhost:5000/emails?token=#{get_token}", :accept => :json
@array = JSON.parse(@results);

把这个翻过来：

[
    {
        "email": {
            "created_at": "2011-03-02T12:23:59Z",
            "updated_at": "2011-03-02T12:23:59Z",
            "value_1": "intevisa@sss.com",
            "value_2": null,
            "id": 4,
            "value_3": null,
            "user_id": 1,
            "value_4": null,
            "desc": "intevisa",
            "privacy": null
        }
    },
    {
        "email": {
            "created_at": "2011-03-02T15:19:39Z",
            "updated_at": "2011-03-02T15:19:39Z",
            "value_1": "another@yahoo.com",
            "value_2": null,
            "id": 5,
            "value_3": null,
            "user_id": 1,
            "value_4": null,
            "desc": "Some text",
            "privacy": null
        }
    },
    {
        "email": {
            "created_at": "2011-03-02T15:20:17Z",
            "updated_at": "2011-03-02T15:20:17Z",
            "value_1": "my@email.com",
            "value_2": null,
            "id": 6,
            "value_3": null,
            "user_id": 1,
            "value_4": null,
            "desc": "Some text",
            "privacy": null
        }
    },
    {
        "email": {
            "created_at": "2011-03-02T15:21:03Z",
            "updated_at": "2011-03-02T15:21:03Z",
            "value_1": "An email@google.com",
            "value_2": null,
            "id": 7,
            "value_3": null,
            "user_id": 1,
            "value_4": null,
            "desc": "Hello world",
            "privacy": null
        }
    }
]

为此：

[

        "email": {
            "created_at": "2011-03-02T12:23:59Z",
            "updated_at": "2011-03-02T12:23:59Z",
            "value_1": "intevisa@sss.com",
            "value_2": null,
            "id": 4,
            "value_3": null,
            "user_id": 1,
            "value_4": null,
            "desc": "intevisa",
            "privacy": null
        },

        "email": {
            "created_at": "2011-03-02T15:19:39Z",
            "updated_at": "2011-03-02T15:19:39Z",
            "value_1": "another@yahoo.com",
            "value_2": null,
            "id": 5,
            "value_3": null,
            "user_id": 1,
            "value_4": null,
            "desc": "Some text",
            "privacy": null
        },

        "email": {
            "created_at": "2011-03-02T15:20:17Z",
            "updated_at": "2011-03-02T15:20:17Z",
            "value_1": "my@email.com",
            "value_2": null,
            "id": 6,
            "value_3": null,
            "user_id": 1,
            "value_4": null,
            "desc": "Some text",
            "privacy": null
        },

        "email": {
            "created_at": "2011-03-02T15:21:03Z",
            "updated_at": "2011-03-02T15:21:03Z",
            "value_1": "An email@google.com",
            "value_2": null,
            "id": 7,
            "value_3": null,
            "user_id": 1,
            "value_4": null,
            "desc": "Hello world",
            "privacy": null
        }

]

这就是我在客户机中尝试循环的方式

<% @array['email'].each do |item| %>

    <%= item['value_1'] %>

<% end %>

在配置>初始化器>wrap_parameters.rb中尝试以下操作

# Enable parameter wrapping for JSON. You can disable this by setting :format to an empty array.
ActionController::Base.wrap_parameters format: [:json]

# Disable root element in JSON by default.
if defined?(ActiveRecord)
  ActiveRecord::Base.include_root_in_json = false
end

通过将“include_root_in_json”设置为false，可以获得所需的输出
