Ruby OpenStates NoMethodError - undefined method `map' - ruby-on-rails

Question

I'm having issues with a Ruby gem that used to work, but now doesn't. It's openstates https://rubygems.org/gems/openstates . The code to find Legislators doesn't seem to work anymore. We have had this code in production for a while, but are now getting this error
NoMethodError - undefined method `map' for #<String:0x007ff0b51941c0>
openstates (0.0.1) lib/openstates/model.rb:37:in `where'
This is the how we are calling the method.
OpenStates::Legislator.where(parameters)
parameters = {:state=>"Ca"}

Answer 1

Your code hasn't changed, the gem hasn't changed, but the API probably has.
Here's a very basic module to help you get an Array from OpenStates::Legislator.where(parameters) :
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)
It outputs :
# Downloading https://openstates.org/api/v1/legislators/?state=Ca
