我是一个菜鸟，在这个问题上苦苦挣扎的时间比我愿意承认的要长。我的 STI 模型曾经有一个路由问题，但现在我认为这已经解决了（感谢 SO）。

我的问题是，一旦我在以下位置更新表格：/kids/1/edit，而不是保存记录，它似乎再次获得记录。我知道我遗漏了一些基本的东西，但是在解决这个问题很长时间之后，我却没有找到答案。您可以看到我在表单提交中明确调用了 Kidupdate 操作。

提前致谢。

Kidedit.html.erb

<% provide(:title, "Edit user") %> 
<h1>Update your profile</h1>

<div class="row">
  <div class="span5 offset3"> 
    <%= form_for(@kid, url: kidedit_path) do |f| %>
      <#%= render 'shared/error_messages', object: f.object %> 

      <%= f.label :fname, "First Name" %>
      <%= f.text_field :fname %> 

      <%= f.label :lname, "Last Name" %>
      <%= f.text_field :lname %> 

      <%= f.label :email %>
      <%= f.text_field :email %> 

      <%= f.label :type, "Are you a Kid or Parent" %>
      <%= f.select :type, [['Kid','Kid'],['Parent','Parent']] %>

      <%= f.label :password %>
      <%= f.password_field :password %>

      <%= f.label :password_confirmation, "Confirmation" %>
      <%= f.password_field :password_confirmation %>

      <%= f.submit "Save changes", class: "btn btn-large btn-primary", :controller => 'users', :action => 'kidupdate' %>
  <% end %>
  </div>
</div>

users_controller.rb

  def kidupdate

    @kid = Kid.find(params[:id])
    if @kid.update_attributes(params[:kid])
      flash[:success] = "Profile updated"
      sign_in @kid
      redirect_to kidshow_path
    else
      render kidedit_path(@kid)
    end
  end

路线.rb

Kidtunes::Application.routes.draw do

  root to: 'static_pages#home'

  match '/help',    to: 'static_pages#help'
  match '/contact', to: 'static_pages#contact'
  match '/signup',  to: 'users#new'
  match '/signin',  to: 'sessions#new'
  match '/signout',  to: 'sessions#destroy', via: :delete

  match 'kids/:id' => 'users#kidupdate', via: :put, :as => :kidupdate
  match 'kids/:id' => 'users#kidshow', via: :get, :as => :kidshow
  match 'kids/:id/edit' => 'users#kidedit', :as => :kidedit

  resources :users
  resources :sessions, only: [:new, :create, :destroy]

这是服务器日志中的内容：

正如第一条评论所说，表单应该使用 update_path 方法：

<%= form_for(@kid, url: kidupdate_path) do |f| %>
