Issue with def get_zip_data

[theword]

Following the documentation on AJAX/JQUERY functionality.
Received the following Error:
wrong number of arguments (given 2, expected 1)

It appeared Zipcode.find_by_code only takes one argument. The Zip Code. Also changed the line on finding counties to @counties = County.first(@zipcode.county_id)

Updated the code below as the following and it is returning the hash on the get call.

 def get_zip_data
    puts 'TEST'
    puts params
    @zipcode = Zipcode.find_by_code(params[:code])
    if @zipcode
      puts 'ZIPCODE---'
      pp @zipcode
      @counties = County.first(@zipcode.county_id)
      data = {
          'state' => @zipcode.state.abbr,
          'county' => @zipcode.county.name,
          'city' => @zipcode.city.titleize
      }
      render :text => data.to_json
    else
      if params[:code].blank?
        return true
      else
        if params[:code].is_zipcode?
          data = {
              'err' => "Could not find Zipcode [#{params[:code]}].  If this is a valid zipcode please notify support <support@mydomain.com>, so we can update our database."
          }
        else
          data = {
              'err' => "[#{params[:code]}] is not a valid Zipcode."
          }
        end
        render :text => data.to_json
      end
    end
  end

@theword thanks for reporting this. The README is actually outdated and shows code for Rails 2. Yikes! 😱

I will see about updating it when I have a chance. A pull request would really help me out though.
