试图让 gmaps4rails 在 rails 3 项目中工作。我根据演示进行了所有设置，但我的视图仅在地图应位于的灰色背景上显示地图控件。在 chrome 和 safari 中尝试过。有什么想法吗？

在模型中：

acts_as_gmappable :process_geocoding => false

def gmaps4rails_address
  "#{address}, #{city}, #{state} #{zip}"
end

在控制器中： 

@venues = Venue.limit(5)
@venue_map_data = @venues.to_gmaps4rails

在视图中： 

<%= gmaps4rails(@venue_map_data) %>

在 application.html.erb 布局中： 

<!DOCTYPE html>
<html>
<head>
  <title>MapTest</title>
  <%= stylesheet_link_tag :all %>
  <%= javascript_include_tag :defaults %>
  <%= csrf_meta_tag %>
  <%= yield :head %>
</head>
<body>
   <%= yield %>
   <%= yield :scripts %>
</body>
</html>

Javascript的东西：

<script src="/javascripts/gmaps4rails.js" type="text/javascript"></script> 
<script type="text/javascript" src='http://google-maps-utility-library-v3.googlecode.com/svn/tags/markerclusterer/1.0/src/markerclusterer_compiled.js'></script> 
<script type="text/javascript" charset="utf-8"> 
function gmaps4rails_init() {
    Gmaps4Rails.map_options.auto_adjust = true;
    Gmaps4Rails.initialize();
    Gmaps4Rails.markers = [{"longitude": "37.742956", "latitude": "-122.421695"},
           {"longitude": "37.742668", "latitude": "-122.421735"},
           {"longitude": "37.742578", "latitude": "-122.42178"},
           {"longitude": "37.742862", "latitude": "-122.421575"},
           {"longitude": "37.743123", "latitude": "-122.421485"}];
    Gmaps4Rails.create_markers();
    if(typeof gmaps4rails_callback == 'function') { gmaps4rails_callback(); }
}

function gmaps4rails_loadScript() {
    var script = document.createElement("script");
    script.type = "text/javascript";
    script.src = "http://maps.google.com/maps/api/js?sensor=false&libraries=geometry&callback=gmaps4rails_init";
    document.body.appendChild(script);
}

window.onload = gmaps4rails_loadScript;

</script>

该死的，来回看了20分钟后才知道...

与宝石无关：查看您的坐标：

Gmaps4Rails.markers = [{"longitude": "37.742956", "latitude": "-122.421695"},
       {"longitude": "37.742668", "latitude": "-122.421735"},
       {"longitude": "37.742578", "latitude": "-122.42178"},
       {"longitude": "37.742862", "latitude": "-122.421575"},
       {"longitude": "37.743123", "latitude": "-122.421485"}]

您将纬度放入经度表中，反之亦然。

经度 = [-180, 180]

纬度 = [-90, 90]
