背景
我正在我的应用程序中实现一项功能,允许用户评价和查看图片.
我的问题源于嵌套审查图片资源中的资源,特别是在我的Review#Edit函数中.错误消息明确声明缺少必需的键:[:id]
错误信息
ActionController::URLGenerationError in Reviews#Edit
No route matches {:action=>"show", :controller=>"reviews", :format=>nil, :picture_id=>#<Review id: 4, username: "DarkMouse", body: "Updating review", picture_id: 11, created_at: "2014-08-14 03:26:52", updated_at: "2014-08-14 03:55:29">, :id=>nil} missing required keys: [:id]
Undefined method 'reviews_path' for #<#<Class:0x45c1b00>:0x39ae810>
Extracted source (Around line #7):

我在Stack Overflow.com上搜索了答案(我的参考文献在底部给出)并被建议这样做.
<td><%= link_to 'Edit', …完整错误:
No route matches {:id=>#<Reminder id: nil, medication: nil, time: nil, created_at: nil, updated_at: nil, user_id: 1>} missing required keys: [:id]
以下是index.html.erb中导致错误的代码:
<tbody>
<% @reminders.each do |reminder| %>
<tr <%= dom_id(reminder) %>>
<td><%= reminder.medication %></td>
<td><%= reminder.time %></td>
<td>
<%= link_to "Edit", edit_reminder_path(reminder) %>
or
<%= link_to 'Remove', reminder, method: :delete, data: { confirm: 'Are you sure?' } %>
</td>
</tr>
<% end %>
</tbody>
楷模:
class Reminder < ActiveRecord::Base
validates :medication, presence: true
belongs_to :user
end
class User < …
