gem'zip-codes'未在rails4中获取法国的zip

Question

Hello I am using gem 'zip-codes' to match the zip-code with given state and city its working fine for US country, state and city. But for FRANCE its not working it as in European countries we don't have states we have province so its not working for that. I have written given code in my model:

validate :zip_and_city_match, on: [:create, :update]

def zip_and_city_match
    @zip = ZipCodes.identify(self.zip)
    if @zip.present?
      unless self.state_code == @zip[:state_code] && self.city == @zip[:city]
        self.errors.add(:zip, 'Does not match the provided city and state')
      end
    else
      self.errors.add(:zip, 'Invalid Zip')
    end
end

If I give country = France, state_code= Île-de-France, city = Paris and zip = 75001 so it gives error Does not match the provided city and state . I had also tried http://blog.joshsoftware.com/2010/08/21/zipcode-validation-using-geokit-in-rails/ this but this also don't work for me. Please help me out how to solve this. Thanks in advance.

this gem 'zip-codes' only supports US zipcode. So i think you should go for other solution. See this file of gem 'zip-codes' US.yml .For more information, you can go through the file of this gem zip-codes
