继续我的传奇，创建一个名为address的多态对象，它与帐户和联系人有一对多的关系（以及将来的其他对象）。
Ruby Polymorphic association working locally but not in heroku
show account视图应该使用多态数据（addressable_id，addressable_type）将参数发送到new_address，在这种情况下是account_id和帐户控制器。
show帐户有以下链接来创建新地址：
<%= link_to new_address_path(:controller => "addresses", :action => "new", :addressable_type => :account, :addressable_id => @accounts.id, ) do %>
<%= (image_tag("address_new.png", :width => "70%")) %>
<br /> New Address
<% end %>
转发网址后显示：
http://vulcanosys.herokuapp.com/addresses/new?addressable_id=1&addressable_type=accounts
表单字段是隐藏的，所以首先我认为这是创建操作中的一个问题，但在设置字段可见后，我可以看到问题是heroku没有使用hash参数填充表单。
虽然在localhost中它完全加载，但网址也显示：
http://localhost:3000/addresses/new?addressable_id=1&addressable_type=accounts
地址/ new.html.erb是以下
<div id="central">
<div id="limiter">
<h1><%= (image_tag("address_new.png", :width => "20%", :align =>"middle")) %> New Address</h1>
<h4>Please insert Account data:</h4>

我在这方面挣扎了一个星期，不知道该怎么做，我甚至在思考硬编码的多态关联。
答案 0 :(得分：0)
我解决了上述问题，执行了以下步骤：
将带有浅层的多态模型地址的嵌套路由应用于忽略编辑，更新和删除操作的关联。
shallow do
resources :accounts do
resources :addresses
end
end
shallow do
resources :contacts do
resources :addresses
end
end
我还在应用程序未完全投入生产时更改了一些设置。
