Ruby on Rails：错误的参数数量（3个为2）

Question

For some reason I am getting an error on this method when I am trying to add a record. The specific error is wrong number of arguments (3 for 2)

    def addrecord
        res=MultiGeocoder.geocode(params[:street], params[:city], params[:state])
        lat, lng = res.ll.split(",") 
        Bathroom.create(:name =>params[:name],
                        :bathroomtype =>params[:bathroomtype],
                        :street =>params[:street],
                        :city =>params[:city],
                        :state =>params[:state],
                        :country =>params[:country],
                        :postal =>params[:postal],
                        :lat => lat,
                        :lon => lng,
                        :access =>params[:access], 
                        :directions =>params[:directions],
                        :comment =>params[:comment],
                        :created => Time.now,
                        :source => 'Squat',
                        :avail =>params[:avail] )
                        respond_to do |format|
                          format.json   { render :nothing => true }                  

                        end

      end

    This is an example call...

> http:..../bathrooms/addrecord?name=Apple%20Store&bathroomtype=1&street=One%20Stockton%20St.&city=San%20Francisco&state=CA&country=United%20States&postal=94108&access=0&directions=&comment=&avail=0

This is the request parms:

Parameters:

 "directions"=>"",

What am I missing?

Any help appreciated.

Answer 1

至少在Geokit的 master中， （我假设您使用的是宝石） ， MultiGeocoder扩展了Geocoder ， geocode的方法签名只需要2个参数 ，一个address和可选的options哈希。

Answer 2

You have to give a location as the first parameter here, and options as the rest:

MultiGeocoder.geocode(params[:street], params[:city], params[:state])

Try to send it as a string, like this:

MultiGeocoder.geocode("#{params[:street]}, #{params[:city]}, #{params[:state]}")
