有没有更好的方法来处理数组响应Rails 4

Question

我正在与Scalable Press API整合。我正在使用HTTparty来处理api响应。

示例请求：

curl "https://api.scalablepress.com/v2/products/gildan-sweatshirt-crew"

回复示例：

{

    }],
    "sizes": [

      "xxxxl",
      "xxxxxl"
    ]
  }],
  "additionalImages": [{
    "label": "Front",
    "url": "http://i1.ooshirts.com/products/5/front.jpg"
  }, {
    "label": "Back",
    "url": "http://i1.ooshirts.com/products/5/back.jpg"
  }, {
    "label": "Collar",

  "available": true,

  "availabilityUrl": "https://api.scalablepress.com/v2/products/gildan-sweatshirt-crew/availability",
  "productId": "gildan-sweatshirt-crew"
}

这个反应并不算太糟糕，但有些产品有50种以上的颜色，每种颜色都有4张左右的颜色。

问题： 我希望使我的代码更好，更容易访问图像。有没有更好的方法来处理数组？

View: <%= image_tag @product['colors'].to_a[0].to_a[2].to_a[1].to_a[1].to_a[0].to_a[1] %>

controller:
def show_product
    @product = scalable_press.show_product(params[:product])
  end

  private

  def scalable_press
    ScalablePress.new
  end

class ScalablePress
  include HTTParty
  base_uri 'https://api.scalablepress.com'

  def initialize
    @options = { basic_auth: { password: 'APIKEY' }, verify: false}
  end

  def products_in_category(category)
    response = self.class.get("https://api.scalablepress.com/v2/categories/#{category}", @options)
    response["products"]
  end

  def categories
    response = self.class.get("https://api.scalablepress.com/v2/categories", @options)
  end

  def show_product(product)
    response = self.class.get("https://api.scalablepress.com/v2/products/#{product}", @options)
    # response["products"]
  end
end
