Ruby on Rails - 表单不填充哈希 - 仅在heroku中，在本地/开发环境中正常工作

时间：2016-01-10 02:31:46

标签： ruby-on-rails ruby heroku polymorphic-associations form-for

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>
    <%= 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 %>

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。

1 个答案:

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。

Config.application.enviroment.production 

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