我正在尝试搜索 10 英里内的用户地址。只要距离在 10 英里以内,它似乎就可以正常工作。但是,如果它超过 10 英里,它会放大到偏僻的地方。任何想法如何修复它,以便如果它不在范围内它不会缩放到随机海洋,甚至更好地给出一条消息说在给定半径内不匹配?

users_controller

class UsersController < ApplicationController
  def index
    if params[:search].present?
      @users = User.near(params[:search], 10)
    else
      @users = User.all
    end

    @hash = Gmaps4rails.build_markers(@users) do |user, marker|
      marker.lat user.latitude
      marker.lng user.longitude
      marker.infowindow user.description
    end
  end
end

index.html.erb

<div id="map-container">
  <div id="map-canvas"></div>
</div>

<%= form_tag users_path, :method => :get do %>
  <p>
  <%= text_field_tag :search, params[:search] %>
  <%= submit_tag "Search Near" %>
  </p>
<% end %>


<script>
$(document).ready(function(){
  handler = Gmaps.build('Google');
  handler.buildMap({ provider: {}, internal: {id: 'map-canvas'}}, function(){
    markers = handler.addMarkers(<%=raw @hash.to_json %>)
    handler.bounds.extendWith(markers);
    handler.fitMapToBounds(markers);
    if(navigator.geolocation)
      navigator.geolocation.getCurrentPosition;
  });
});
</script>
