无法覆盖Google Maps API通过Gmaps4Rails Gem访问的bootsrap css [英] Having trouble overriding bootsrap css for Google Maps API accesssed through Gmaps4Rails Gem

问题描述

我遵循Gmaps4Rails教程，并试图在引导框架中实现它，但我有问题。地图将无法正确加载... 请参阅此处。放大功能不起作用。 / p>

我尝试了解决方法，但它只是有点帮助。这似乎是一个问题，如何设置bootstrap，或者我的需要树不正确。请参阅下面的相关代码。

views / layouts / application.html.erb

 $ b < >解决方案
我有同样的问题。您可以尝试使用地理位置方法，并将地图设置为以用户的位置为中心。检查它的工作。 
  if（navigator.geolocation）
 navigator.geolocation.getCurrentPosition（displayOnMap）; 
 
 function displayOnMap（position）{
 var marker = handler.addMarker（{
 lat：position.coords.latitude，
 lng：position.coords.longitude， 
 picture：{
 url：Keep Any Image，
 width：36，
 height：36 
}，
 infowindow：You
}）; 
 handler.map.centerOn（marker）; 
}

创建google地图
  var handler = Gmaps.build（'Google'）; 
 handler.buildMap（{internal：{id：'map'}}，function（）{
 if（navigator.geolocation）
 navigator.geolocation.getCurrentPosition（displayOnMap）; 
}）; 
 
 function displayOnMap（position）{
 var marker = handler.addMarker（{
 lat：position.coords.latitude，
 lng：position.coords.longitude， 
 picture：{
 url：/images/pin_blue.png，
 width：36，
 height：36 
}，
 infowindow：你在这里！
}）; 
 handler.map.centerOn（marker）; 
 
} 
  
 此脚本从表中读取数据，添加标记  
  $（＃googlemaps b $ b var array = []; 
 var headers = []; 
 $（'＃tweetstable th'）。each（function（index，item）{
 headers [index] $（item）.html（）; 
}）; 
 $（'＃tweetstable tr'）。has（'td'）。 }; 
 $（'td'，$（this））。each（function（index，item）{
 arrayItem [headers [index]] = $（item）.html $ b}）; 
 array.push（arrayItem）; 
}）; 
 handler.addMarkers（array）; 
 handler.bounds.extendWith（array）; 
 handler.fitMapToBounds（）; 
}）; 
  
 
I am following the Gmaps4Rails tutorial and trying to implement it in a bootstrap framework, but am having problems.  The map won't load correctly...  See here.  Zooming in function does not work.

I tried the workaround but it has only helped marginally.  This appears to be a problem with how bootstrap is set up, or perhaps my require tree is not correct.  See below for my relevant code.

views/layouts/application.html.erb
<!DOCTYPE html>
<html>
  <head>
    <title><%= full_title(yield(:title)) %></title>

    <%= stylesheet_link_tag "application", media: "all",
                            "data-turbolinks-track" => true %>
    <%= javascript_include_tag "application", 
                               "data-turbolinks-track" => true %>
    <%= csrf_meta_tags %>
    <%= render 'layouts/shim' %>
    <% flash.each do |key, value| %>
      <%= content_tag(:div, value, class: "alert alert-#{key}") %>
    <% end %>
  </head>
...

custom.css.scss --> this is the main stylesheet for my app, and I added the workaround code here just to see if it would make a difference, but it did not.
@import "bootstrap";

/*MAP*/

#map img { 
  max-width: none;
}
#map label { 
  width: auto; display:inline; 
} 
...

application.css
...
 * You're free to add application-wide styles to this file and they'll appear at the top of the
 * compiled file, but it's generally better to create a new file per style scope.
 *
 *= require_self
 *= require_tree .

Any help is much appreciated :)
解决方案
I had this same problem. Could you try using geolocation method and set the map centered on user's location. Check it its working.   
if(navigator.geolocation)
navigator.geolocation.getCurrentPosition(displayOnMap);

 function displayOnMap(position){
 var marker = handler.addMarker({
 lat: position.coords.latitude,
 lng: position.coords.longitude,
 picture: {
      url: "Keep Any Image",
      width:  36,
      height: 36
    },
    infowindow: "You"
});
handler.map.centerOn(marker);
}
Updated answer

tweetsfromdb.html.erb
<table class="table table-striped" style='width: 100%; display:none;' id="tweetstable" >
<tr><th>Picture</th>
<th>infowindow</th>
 <th>lat</th>
<th>lng</th></tr>
<% for tweet in @tweets %>
<tr>
<td> <%=tweet.profile_pic%> </td>
<td> <img src="<%=tweet.profile_pic%>" class="img-circle"/>
<%=tweet.tweet_text%>  <b><i>Location:<%=tweet.location%></i></td>
<td>  <%=tweet.lattitude%></td>
<td>  <%=tweet.longitude%></td>
 <% end %>
</table>
The lattitude and longitude have been identified by geocoding the locations

script
To Create the google maps
var handler = Gmaps.build('Google');
handler.buildMap({ internal: {id: 'map'} }, function(){
  if(navigator.geolocation)
navigator.geolocation.getCurrentPosition(displayOnMap);
});

function displayOnMap(position){
  var marker = handler.addMarker({
    lat: position.coords.latitude,
    lng: position.coords.longitude,
    picture: {
      url: "/images/pin_blue.png",
      width:  36,
      height: 36
    },
    infowindow: "You are here !"
  });
 handler.map.centerOn(marker);

}
This script reads the data from the table and adds the markers
 $("#googlemaps").click(function(){

  var array = [];
    var headers = [];
 $('#tweetstable th').each(function(index, item) {
    headers[index] = $(item).html();
});
$('#tweetstable tr').has('td').each(function() {
    var arrayItem = {};
    $('td', $(this)).each(function(index, item) {
        arrayItem[headers[index]] = $(item).html();
    });
    array.push(arrayItem);
});
handler.addMarkers(array);
handler.bounds.extendWith(array);
handler.fitMapToBounds();
});
