Google Maps, Ruby on Rails, Zoom level with one marker

I am adding google maps support with apneadiving / Google-Maps-for-Rails (thanks awesome gem) I am finding one slight glitch, however, which very likely is my fault. auto_zoom works great when there are multiple markers. However, when there is only one marker it is zoomed in to the max level which is not pretty. "zoom" will only work when auto_zoom is false, so that's not what I want. So therefore you could use "maxZoom" but now users cannot zoom in manually beyond that point which is not what I want. Is there a way around this? Is my explanation making sense? Is this a limitation of Google

问题 How do I load only markers that are inside the map bounds with gmaps4rails? And of course load new ones after pan and/or zoom. Directly related to that, how can I get the current boundaries and zoomlevel of the map? 回答1: Here is how I did it, I only replace the markers after the user finishes panning or zooming, if you require different behavior then use a different event listener: In your view (index.html.erb): <%= gmaps({ "map_options" => { "zoom" => 15, "auto_adjust" => false, "detect
