Question

我在使用GeoKit进行邮政编码搜索时遇到问题。一些错误使整个应用程序崩溃。

这就是我所拥有的：

 def zipcode
    zipcode = params[:zipcode]
    @bathrooms = Bathroom.geo_scope(:all, :origin=>[zipcode], :within=>10)
    respond_to do |format|
      format.json  { render :json => @bathrooms }
      #format.json { render :json => {:bathrooms => @bathrooms} }
      format.js   { render :nothing => true } 
     end        
  end




 match '/bathrooms/zipcode', :controller => 'bathrooms', action =>"zipcode"

这是我得到的错误：

 ArgumentError in BathroomsController#zipcode

wrong number of arguments (2 for 1)

Answer 1

geo_scope期待only one argument：哈希。您传递两个参数：符号（:all）和哈希（:origin=>[zipcode], :within=>10）。当它只期望一个时，它接收两个参数，给你错误：

wrong number of arguments (2 for 1)

有两种方法可以解决这个问题。

首先，您可以删除:all符号并使用取景器方法：

Bathroom.geo_scope(:origin=>[zipcode], :within=>10).all

或者，您可以完全忘记GeoKit并使用geocoder代替。 (github)

# GeoKit
@bathrooms = Bathroom.geo_scope(:origin=>[zipcode], :within=>10).all

# geocoder
@bathrooms = Bathroom.near(zipcode, 10)

Ruby on Rails：GeoKit Zipcode搜索？
