ruby-on-rails - Google Maps for Rails - 标记中心始终最大缩放

Question

我正在为 rails 使用谷歌地图，我已经正确设置了所有内容，但我似乎无法弄清楚如何设置默认缩放数字。我尝试在 gmaps4rails.base.js.coffee 中设置它:

@default_map_options = 
      id: 'map'
      draggable: true
      detect_location: false  # should the browser attempt to use geolocation detection features of HTML5?
      center_on_user: false   # centers map on the location detected through the browser
      center_latitude: 0
      center_longitude: 0 
      zoom: 7
      maxZoom: null
      minZoom: null
      auto_adjust : true      # adjust the map to the markers if set to true
      auto_zoom: true         # zoom given by auto-adjust
      bounds: []              # adjust map to these limits. Should be [{"lat": , "lng": }]    
      raw: {}                  # raw json to pass additional options

但我认为这不能正常工作。有没有办法在创建 map 时添加缩放数字:

<%= gmaps(:markers => {:data => @json, 
                      :options => {:raw => '{ animation: google.maps.Animation }' } },
                      :map_options => { :raw => '{ disableDefaultUI: false, 
                                                   scrollwheel: true }' }) %>

我所做的一切似乎都无济于事，它总是一直放大。谢谢!

这是我的解决方案，它有效(注意我使用 haml 。使用 <%= %> 代替 erb):

= gmaps("map_options" => { "detect_location" => true, "center_on_user" => true, "auto_zoom" => false, "zoom" => 16},"markers" => { "data" => @json })
