Ruby OpenStates NoMethodError - 未定義的方法`map'

我遇到過用於工作的Ruby寶石，但現在沒有問題。這是開放狀態https://rubygems.org/gems/openstates。尋找立法者的代碼似乎不再適用。我們已經有這段代碼在生產一段時間，但現在得到這個錯誤Ruby OpenStates NoMethodError - 未定義的方法`map'

NoMethodError - undefined method `map' for #<String:0x007ff0b51941c0> 

openstates (0.0.1) lib/openstates/model.rb:37:in `where'

這是我們如何調用方法。

OpenStates::Legislator.where(parameters) 

parameters = {:state=>"Ca"}

如果這是工作，現在由於更新你已經完成了你的寶石，最新版本有一個錯誤，指定這個寶石的版本，這是不是在你的gemfile中的越野車，並應該工作 – amrdruid

它仍然是我一直使用的寶石的相同版本。版本0.0.1 – user2974739

我建議你用'gem'和'openstates'或'OpenStates'替換你的標籤'Rubygems'。 –

你的代碼沒有改變，gem沒有改變，但API可能有。

這裏是一個非常基本的模塊，幫助你從OpenStates::Legislator.where(parameters)數組：

require 'open-uri' 
require 'active_support/core_ext/object' 

module OpenStates 
    class Legislator 
    @cache={} 
    class << self 
     def where(parameters) 
     url = "https://openstates.org/api/v1/legislators/?#{parameters.to_query}" 
     @cache[url] ||= get_json(url) 
     end 

     private 

     def get_json(url) 
     puts "# Downloading #{url}" 
     sleep 2 
     JSON.load(open(url)) 
     end 
    end 
    end 
end 

parameters = {:state=>"Ca"} 
p OpenStates::Legislator.where(parameters).first(2)

它輸出：不，這可能發生
