ruby-on-rails-3.2 - 地图显示不好

Question

在索引操作中工作时一切正常，但是当我尝试在显示视图中显示地图时，它不能很好地显示。

控制器.rb：

def show
  @person = Person.find(params[:id])
  @json = Person.find(params[:id]).to_gmaps4rails

  respond_to do |format|
    format.html # show.html.erb
    format.json { render json: @person }
  end
end

显示.html.erb：

<div class="tabbable">
  <ul class="nav nav-tabs">
    <li class="active"><a href="#profile" data-toggle="tab">Profile</a></li>
    <li><a href="#places" data-toggle="tab">Places</a></li>
  </ul>

  <div class="tab-content">
    <div class="tab-pane fade active in" id="profile">
      Some text here...
    </div>
    <div class="tab-pane fade" id="places">
      <%= gmaps(:map_options => {:type => "ROADMAP"},
                :markers => {:data => @json,
                             :options => {"list_container" => "markers_list" }}) %>
    </div>
  </div>
</div>

模型.rb：

acts_as_gmappable

def gmaps4rails_address
  address 
end

def gmaps4rails_infowindow
  "<h3><img src=\"#{self.avatar(:thumb)}\"> #{ERB::Util.json_escape name.humanize}</h3>
   <hr/>
   <h4>#{ERB::Util.json_escape address.humanize}</h4>"
end

def gmaps4rails_sidebar
  "<span>#{name.humanize}</span>" #put whatever you want here
end

有任何想法吗？这是屏幕截图的链接： http: //cl.ly/2x2H002e3O0P1w0R0b3K
