ruby - gmaps4rails 不显示 map

Question

按照有关开始运行 Gmaps4rails 的 YouTube 视频，我无法让它显示 map 。 (Rails 3.1.3, gmaps4rails 1.3.2)

该页面在头部包含正确的 javascript Assets ...

<script src="/assets/gmaps4rails/gmaps4rails.base.js?body=1" type="text/javascript"></script>
<script src="/assets/gmaps4rails/gmaps4rails.bing.js?body=1" type="text/javascript"></script>
<script src="/assets/gmaps4rails/gmaps4rails.googlemaps.js?body=1" type="text/javascript"></script>
<script src="/assets/gmaps4rails/gmaps4rails.mapquest.js?body=1" type="text/javascript"></script>
<script src="/assets/gmaps4rails/gmaps4rails.openlayers.js?body=1" type="text/javascript"></script>

...包含 map 的正确占位符...

<div class="map_container"> 
  <div id="map" class="gmaps4rails_map"></div>
</div>

脚本是在我 body 的末尾生成的:

<script type="text/javascript" src="//maps.google.com/maps/api/js?v=3.5&sensor=false&amp;libraries=geometry"></script>
<script type="text/javascript" src="//google-maps-utility-library-v3.googlecode.com/svn/tags/infobox/1.1.9/src/infobox_packed.js"></script>
<script type="text/javascript" src="//google-maps-utility-library-v3.googlecode.com/svn/tags/markerclustererplus/2.0.5/src/markerclusterer_packed.js"></script>
<script type="text/javascript" src="//google-maps-utility-library-v3.googlecode.com/svn/trunk/richmarker/src/richmarker-compiled.js"></script>  

<script type="text/javascript" charset="utf-8">

Gmaps.map = new Gmaps4RailsGoogle();
Gmaps.load_map = function() {
Gmaps.map.map_options.auto_adjust = true;
Gmaps.map.initialize();
Gmaps.map.markers = [{"lng": "4.481594", "lat": "51.194179"}];
Gmaps.map.markers_conf.do_clustering = true;
Gmaps.map.create_markers();
Gmaps.map.adjustMapToBounds();
Gmaps.map.callback();
};    
window.onload = function() { Gmaps.loadMaps(); };

</script>

所有部件似乎都已就位，但它什么也没做。我不确定如何调试它。我错过了一些重要的事情吗？

Answer 1

gmaps4rails 的样式表没有包含在我的页面中，因为我用自己的样式覆盖了默认的 application.css。结果， map 没有显示。

确保需要 gmaps4rails.css 解决了问题。

<%= stylesheet_link_tag "gmaps4rails" %>
