ruby-on-rails - 用于查找邮政编码的 Ruby Geocoder gem

Question

我正在使用 ruby​​ geocoder gem 按位置进行搜索。我想将搜索限制在已正式启动的位置。如果有人按 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，则返回搜索结果。

geocoder api有一个反向地理编码部分:

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。但是我试图在我的 Controller 中使用它，但是 obj.zipcode 根本不起作用。 Geocoder.search('san jose, ca') 似乎返回了我需要的东西，我只是不知道如何找到它。这是我所在的位置:

  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

试试 Area gem .你可以这样做:

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