我期待在這裏澄清我的理解或真正理解......我有像這樣節約JSON響應爲對象軌道

AA JSON響應，我想救它以點擊的link_to後，我的書一定的模型值（我已閱讀的link_to比說button_to更安全）
所以我有一個處理包含在我的控制器解析模塊
module Book::BookFinder
BOOK_URL = 'https://itunes.apple.com/lookup?isbn='
def book_search(search)
response = HTTParty.get(BOOK_URL + "#{search}", :headers => { 'Content-Type' => 'application/json', 'Accept' => 'application/json' })
results = JSON.parse(response.body)["results"]
end
end
在我的書控制器
class BookController < ApplicationController
before_filter :authenticate_admin_user!
include Book::BookFinder
def searchbook
end
def results
results = book_search(params[:search])
@results = results
end
def savebook
Book.create(:author => response["results"]["artistName"])
end
end
（首先，我看這個，認爲使用Rails寧靜的做法會比較好，所以使用新創建的方法呢？）
我有一個的link_to設置把數據上傳到我的模型
<%= link_to 'Save Book', savebook_path, :method => :post %>
和我的路線
scope :controller => :book do
get 'searchbook'
get 'results'
post 'savebook'
end
所以目前我在點擊link_to的時候收到錯誤信息，說錯誤的參數個數（0代表1）。
，因爲我收到的數據外已拋出我一點點，用新的形式發佈數據打交道時，創建，編輯等它是有道理的，但在這裏，我有點失去
任何人都可以提供一些建議/解決方案，以幫助我瞭解需要採取什麼
感謝
是什麼，而不是
使用
而且絕對標準圖書控制器這條線呢？ 'json_response = JSON.parse [「結果」]'？應該解析和存儲的json響應在哪裏？ – dimuch
我的印象是這條線分析返回的JSON對象？ – Richlewis
根本不是。 'json_response = JSON.parse [「results」]'就像'res = JSON.parse''json_response = res ['results']''。 – dimuch
