Question

我有一个应用程序（RoR 3.1），用户可以在其中更改企业的Google地图标记的位置（使用“业务控制器”处理）。点击“保存新位置”按钮后，用户应重定向到business＃show页面。但他不是，虽然服务器日志显示业务#show已呈现。无论如何，该位置在数据库中正确保存，但我仍然留在业务#updatemap页面。

以下是用户可以更改地图位置的视图代码：

<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?v=3.6&sensor=false&region=IN"></script>
<script type="text/javascript">
  function initialize() {

    var myLatlng = new google.maps.LatLng(<%= @business.latitude %>, <%= @business.longitude %>);

    var options = {
      zoom: 14,
      center: myLatlng,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    }

    var map = new google.maps.Map(document.getElementById("map_canvas"), options);

    var marker = new google.maps.Marker({
        position: myLatlng,
        map: map,
        draggable:true
    });

    google.maps.event.addListener(
        marker,
        'drag',
        function() {
            document.getElementById('business_latitude').value = marker.position.lat();
            document.getElementById('business_longitude').value = marker.position.lng();
        });
  }
</script>

<body onload="initialize()">
<div id="map_canvas" style="width:500px;height:500px;">
</div>

<%= form_for :business, :url => { :action => "updatemap" }, :remote => true do |f| %>
  <%= f.hidden_field :latitude %>
  <%= f.hidden_field :longitude %>
  <%= f.submit %>
<% end %>

这是业务控制器的相关部分：

 def updatemap
    @business = Business.find(params[:id])
    if @business.update_attributes(params[:business])
      redirect_to @business, :flash => { :success => "The business was 
                                                      successfully updated!" }
    else
      redirect_to root_path
    end
  end

这是服务器日志：

Completed 200 OK in 155ms (Views: 61.0ms | ActiveRecord: 8.1ms)

所以它表示已经渲染了business / show.html.haml，但我仍然在可以更改地图位置的页面上。

有谁知道这里发生了什么？我想这是一个非常简单的问题，但由于我对编码很陌生，所以欢迎任何帮助。

您需要从:remote => true中移除form才能进行重定向。

此致

Rails控制器中的Redirect_to不起作用，但服务器日志将页面显示为已呈现
