Ruby Geocoder gem找到邮政编码

Question

我正在使用ruby geocoder gem按位置搜索.我想将搜索限制在已正式启动的位置.如果有人通过zip搜索,使用正则表达式很容易.但如果有人按城市搜索,我需要将城市转换为邮政编码,检查我的邮政编码表,如果是肯定的,则返回搜索结果.

该地理编码器API具有用于反向地理编码的区段:

reverse_geocoded_by :latitude, :longitude do |obj,results|
  if geo = results.first
    obj.city    = geo.city
    obj.zipcode = geo.postal_code
    obj.country = geo.country_code
  end
end
after_validation :reverse_geocode

这显然是为了在模型中使用而构建的.但我试图在我的控制器中使用它,但是obj.zipcode根本不起作用.Geocoder.search('san jose,ca')似乎回归了我需要的东西,我只是不知道如何去做.这是我在的地方:

  if params[:search].present?
#       coords = Geocoder.coordinates(params[:search])
    zip = Geocoder.search(params[:search])
    if Zip.where(:zip => (params[zip.zipcode]), :launch => true).exists?
      addresses = Address.near(params[:search], 25, :order => :distance)
      @profiles = addresses.map{ |ad| ad.profile }.uniq unless addresses.nil?
      @title = "Addresses Near " + (params[:search]).to_s
    else
      if Zip.where(:zip => (params[zip.zipcode]), :nearlaunch => true).exists?
        addresses = Address.near(params[:search], 25, :order => :distance)
        @profiles = addresses.map{ |ad| ad.profile }.uniq unless addresses.nil?
        @title = "We have not launched for your location but these are near by " + (params[:search]).to_s
      else
        redirect_to :controller => 'pages', :action => 'notlaunched'
      end
    end

Answer 1

尝试区域宝石.你可以这样做:

"San Jose, CA".to_zip #=> ["95101", "95102", ...
