Ruby on rails Can'；t将JSON数据映射到模型,ruby-on-rails,json,ruby-on-rails-4,Ruby On Rails,Json,Ruby On Rails 4,当前正在尝试调用API并将属性映射到我的模型。e、 g.在我的模型中，从JSON响应到图像字符串的image_src字符串。但现在它得到了错误“没有将字符串隐式转换为整数” Feed.rb require 'httparty' require 'json' class Feed < ActiveRecord::Base include HTTParty base_uri 'https://extraction.import.io/query/runtime' has_many

当前正在尝试调用API并将属性映射到我的模型。e、 g.在我的模型中，从JSON响应到图像字符串的image_src字符串。但现在它得到了错误“没有将字符串隐式转换为整数”
Feed.rb

require 'httparty' require 'json' class Feed < ActiveRecord::Base include HTTParty base_uri 'https://extraction.import.io/query/runtime' has_many :entries # GET /feeds # GET /feeds.json def fetch_data response = self.class.get("/2365205f-8502-439e-a6d2-73988cfa03f1?&url=http%3A%2F%2F%2F") @elements = response.parsed_response["extractorData"] @elements.map do |image_info| self.entries.create(image: image_info['url']) end end end

class Entry < ActiveRecord::Base belongs_to :feed end
任何帮助都会很好

response = self.class.get("/2365205f-8502-439e-a6d2-73988cfa03f1?&url=http%3A%2F%2F%2F") puts response.parsed_response

是否尝试获取url或img src之类的内容？我想将每个图像->src映射到模型中的“图像”字段OK，请参阅更新的答案。由于我已从请求中删除了API密钥，身份验证失败；）。您能在原始模型中包含答案吗？我将把你的补充放在哪里？谢谢你的回答，很好，你删除了API密钥。关于“您能在原始模型中包含答案吗？”，它在原始模型中。我已经更新了答案。
