Ruby on rails RubyonRails——表单不是从散列中填充的——仅在heroku中，在本地/开发环境中工作良好

继续我的故事，创建一个名为address的多态对象，它与帐户和联系人（以及将来的其他对象）有一对多的关系

show account视图应使用多态数据（可寻址\u id、可寻址\u类型）将参数发送到新的\u地址，在本例中，多态数据是帐户\u id和帐户控制器

show帐户具有以下链接以创建新地址：

<%= 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 %>

表单字段是隐藏的，所以首先我认为这是create操作中的一个问题，但是在设置字段visible之后，我可以看到问题是heroku没有用hash上的参数填充表单

在localhost中，它可以完美加载，并且URL还显示：

    http://localhost:3000/addresses/new?addressable_id=1&addressable_type=accounts

地址/new.html.erb如下所示

    <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>
    <%= form_for @addresses, url: {action: "create"} do |f| %>
<table class="tshow" align="left" style="width:100%;">
    <col width="50%">
    <col width="50%">
        <%= f.text_field :addressable_type %>
        <%= f.text_field :addressable_id %>
<tr class="even">
        <td><%= f.label :no, "No:" %>*</td>
        <td><%= f.text_field :no %></td>
    </tr>
        <tr class="odd">
        <td><%= f.label :street, "Street:" %>*</td>
        <td><%= f.text_field :street %></td>
    </tr>
    <tr class="even">
        <td><%= f.label :suburb, "Suburb" %>*</td>
        <td><%= f.text_field :suburb %></td>
    </tr>
            <tr class="odd">
        <td><%= f.label :code, "Zip:" %>*</td>
        <td><%= f.text_field :code %></td>
    </tr>
    </table>
</div>
<div id="menu">
<ul class="menu">
    <!-- Access Check - Create New Account -->
    <% if Accessrule.find_by(role_id: current_user.role_id, workspace:2).try(:canwrite?) %>
    <li><%= f.submit " ", :type => :image, :src => image_path("address_save.png"), :width =>"60%" %>
    <br /> <%= f.submit "Save Address", class: "savetext" %><% end %></li>
    <% end %>
    <!-- back Accounts -->
    <li> <%= link_to :back do  %>
    <%= (image_tag("address_back.png", :width => "60%")) %>
    <br /> Back
    <% end %> 
    </li>
    </li>
    </ul>
</div>
</div>

在heroku中，这是一种行为：

我为此苦苦挣扎了一周，不知道该怎么办，我甚至在考虑对多态关联进行硬编码。

我通过以下步骤解决了上述问题：

将嵌套路由应用到具有浅层的多态模型地址，这将忽略编辑、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

当应用程序尚未完全投入生产时，我还更改了一些设置

Config.application.environment.production

    config.assets.digest = true
    config.eager_load = false
