好吧，请耐心等待...我有点新。 我能够搜索我的数据库并使用Gmaps 4rails在Google地图上绘制结果，但我无法添加到"信息窗口"。 所以我决定使用一种不同的搜索方法，我可以渲染一个文件，但它绘制的比我搜索的内容要多得多。 基本上，我需要搜索我的数据库并在谷歌地图上自动绘制结果，然后将这些对象的数据放在信息窗口标记中。
我的 Search.html.erb 文件中的第一个搜索方法适用于绘图，但由于我想的 json 错误，我无法将数据传递到信息窗口中。

My second method for the search .html .erb file, where I can pass the info window, but it plots more then my search results, so If I search for four items it will plot 30 since that is my limit for will_paginate.

这是我的搜索控制器：
class SearchController < ApplicationController
def search
if params[:term].nil?
@businesses = []
else
@businesses = Article.search params[:term]
end
end
end
我的业务信息页面的标记窗口，在第二个示例中工作：
<b>Name:</b> <%= name %><br>
<b>City:</b> <%= city %><br>
有没有办法将一些数据传递到该信息窗口中，不幸的是我已经尝试了所有方法，但只能传递字符串。 谢谢。
我想通了。 当我搜索项目时...我的搜索控制器返回@businesses。 然后@businesses传递给我的标记生成器，称为load_businessz。 然后在我的业务控制器中，我有一个返回@businesses的搜索方法，然后在底部我必须运行该方法load_businessz，它只为我搜索的项目构建标记。 然后在我的视图文件中，我传递由方法 load_businessz 创建的变量@businessz_default。 现在它谷歌地图只填充我搜索的对象。
