HTTParty - 參數的個數錯誤 - 活動記錄模式

Question

我有這個在我的Active Record模式：

class ItemImage < ActiveRecord::Base 
    belongs_to :item, :foreign_key => :upc, :primary_key => :upc 

    include HTTParty 
    format :xml 

    base_uri 'https://myapi.com/v2' 
end 

每當我試圖做這樣的事情在控制檯：ItemImage.first時，Rails引發此錯誤：

ArgumentError: wrong number of arguments (0 for 1)

我是新來的HHTParty，所​​以我真的不知道發生了什麼事情。我想知道這是否與我在活動記錄模型中使用HTTParty相關。我見過的大多數例子都是在ActiveRecord之外使用它的。任何幫助解決這個問題？提前致謝！

它似乎是HTTParty gem和Rails之間的命名衝突，特別是ActiveRecord記錄查詢時的記錄器組件，這是由於將HTTParty模塊直接包含到基於ActiveRecord的類中而引起的。

編輯地址註釋：

沒有理由不能在AR模型在有意義使用HTTParty。你不能在模型中包含HTTParty方法。所以，雖然你不能將樣品用方便的方法來設置格式和基本URI一樣，你應該能夠使用它像這樣：

response = HTTParty.get('https://myapi.com/v2/some-action', :format => :xml) 

你可能還需要像其他選項：查詢，等等。將ItemImage類中的邏輯保存或將其提取到可包含HTTParty的單獨的庫類中是否更容易取決於您的應用程序。
