我努力让我的谷歌地图在我的Rails应用程序中运行。
一切正常 - 我继续研究下一个功能,然后回来发现它不再适用。
我有地址,个人资料和项目的模型。我在每个配置文件和项目中使用地址在每种情况下,地图都不会显示。
模型之间的关联是:
地址
belongs_to :addressable, :polymorphic => true
资料
has_many :addresses, as: :addressable
accepts_nested_attributes_for :addresses, reject_if: :all_blank, allow_destroy: true
项目
has_many :addresses, as: :addressable
accepts_nested_attributes_for :addresses, reject_if: :all_blank, allow_destroy: true
控制器显示的功能是:
地址
def create
@address = Address.new(address_params)
authorize @address
respond_to do |format|
if @address.save
format.html { redirect_to @address, notice: 'Address was successfully created.' }
format.json { render :show, status: :created, location: @address }
else
format.html { render :new }
format.json { render json: @address.errors, status: :unprocessable_entity }
end
end
end
资料
def show
# debugger
@profile = Profile.includes(:industries).find(params[:id])
# @organisation = Organisation.find(params[:organisation_id])
# @profiles = @organisation.profiles
@addresses = @profile.addresses
@hash = Gmaps4rails.build_markers(@addresses) do |address, marker|
marker.lat address.latitude
marker.lng address.longitude
marker.infowindow address.full_address
end
end
项目
def show
@invite = Invite.new
@project = Project.find(params[:id])
@addresses = @project.addresses
@hash = Gmaps4rails.build_markers(@addresses) do |address, marker|
marker.lat address.latitude
marker.lng address.longitude
marker.infowindow address.full_address
end
在我的个人资料中,我有:
<%= render partial: "profiles/main_address" %>
在个人资料/主要地址中,我有:
<script src="//maps.google.com/maps/api/js?v=3.18&sensor=false&client=&key=&libraries=geometry&language=&hl=®ion="></script>
<script src="//google-maps-utility-library-v3.googlecode.com/svn/tags/markerclustererplus/2.0.14/src/markerclusterer_packed.js"></script>
<script src='//google-maps-utility-library-v3.googlecode.com/svn/tags/infobox/1.1.9/src/infobox_packed.js' type='text/javascript'></script> <!-- only if you need custom infoboxes -->
<div style='width: 800px;'>
<div id="map" style='width: 800px; height: 400px;'></div>
</div>
<script>
handler = Gmaps.build('Google');
handler.buildMap({ provider: {}, internal: {id: 'map'}}, function(){
markers = handler.addMarkers(<%=raw @hash.to_json %>);
handler.bounds.extendWith(markers);
handler.fitMapToBounds();
handler.getMap().setZoom(8);
});
</script>
我在我的项目文件夹中有相同的过程来显示项目地址。
在我的宝石文件中,我有:
gem 'google-api-client', '~> 0.7.1', require: 'google/api_client'
gem 'gmaps4rails', '~> 2.1', '>= 2.1.2'
gem 'underscore-rails'
我无法弄清楚为什么我只是得到一个空格而不是显示地址的地图。
在我的控制台检查器中,我可以看到一条红色错误,上面写着:
primitives.self-5b8a3a6….js?body=1:16 Uncaught ReferenceError: MarkerClusterer is not definedGmaps.Google.Primitives @ primitives.self-5b8a3a6….js?body=1:16Gmaps.Objects.Handler.Handler.setPrimitives @ handler.self-2f220ca….js?body=1:122Handler @ handler.self-2f220ca….js?body=1:8Gmaps.build @ base.self-8dd1d1a….js?body=1:9(anonymous function) @ 14:760
搜索错误,Uncaught ReferenceError:未定义MarkerClusterer,宝石制造商建议运行:
rails generate gmaps4rails:install
当我尝试时,我收到一条错误消息:
Running via Spring preloader in process 93390
Could not find generator 'gmaps4rails:install'. Maybe you meant 'paper_trail:install', 'gmaps4rails:copy_js' or 'responders:install'
我的控制台检查器还显示了许多与gmaps相关的警告,如:
Google Maps API warning: NoApiKeys https://developers.google.com/maps/documentation/javascript/error-messages#no-api-keys
util.js:220 Google Maps API warning: RetiredVersion https://developers.google.com/maps/documentation/javascript/error-messages#retired-version

我有一个api密钥 - 我只是不知道把它放在我的代码中。
任何人都可以看到如何提供帮助。如果我不能解决Gmaps的警告问题,我不介意,但我确实想回到地图显示时的状态。
答案 0 :(得分:0)
所以你的问题是这两行:
<script src="//google-maps-utility-library-v3.googlecode.com/svn/tags/markerclustererplus/2.0.14/src/markerclusterer_packed.js"></script>
<script src='//google-maps-utility-library-v3.googlecode.com/svn/tags/infobox/1.1.9/src/infobox_packed.js' type='text/javascript'></script>
有人直接从Google SVN引用了markerclusterer
和infobox
个图书馆(这是一个不好的做法),几周前图书馆被移到了Github。
您可以将infobox
库从here下载到您的项目并参考infobox_packed.js
文件:
<script src='path/to/infobox_packed.js' type='text/javascript'></script>
同样,您可以下载标记聚类库here。小心:对于标记群集,您需要src
和images
。
请阅读此SO question and answers,this one以及this one。我强烈建议你阅读问题中的所有答案,因为其中一些包含错误的解决方案(来自新github位置的参考库,而不是将它们下载到你的项目并从那里引用它们是不好的做法)
