Ruby on rails 3 Rails在不同的控制器中更新

你好，我正在做简单的更新

记录的客户控制器.rb

class LoggedCustomerController < ApplicationController

  before_filter :authorize
  helper_method :current_customer

  layout "frontend"

  def current_customer
    @current_customer ||= Customer.find(session[:customer_id]) if session[:customer_id]
  end

  def authorize
    if session[:auth] != true
      redirect_to login_path, :notice => "Not logged."
    end
  end

  def show
  end

  def edit
  end

  def update
    respond_to do |format|
      if current_customer.update_attributes(params[:current_customer])
        format.html { redirect_to view_path, notice: 'Customer was successfully updated.' }
        format.json { head :no_content }
      else
        format.html { render action: "edit" }
        format.json { render json: current_customer.errors, status: :unprocessable_entity }
      end
    end
  end

end

  match "view" => "logged_customer#show", :via => :get
  match "edit" => "logged_customer#edit", :via => :get
  match "edit" => "logged_customer#edit", :via => :put

    <%= form_for current_customer, :url => url_for(:controller => 'logged_customer', :action => 'edit'), :html => { :class => 'form-horizontal' } do |f| %>

<% if current_customer.errors.any? %>
  <div id="error_explanation">
    <div class="alert alert-error">
      The form contains <%= pluralize(current_customer.errors.count, "error") %>.
    </div>
    <ul>
    <% current_customer.errors.full_messages.each do |msg| %>
      <li> <%= msg %></li>
    <% end %>
    </ul>
  </div>
<% end %>

...

edit.html.erb

class LoggedCustomerController < ApplicationController

  before_filter :authorize
  helper_method :current_customer

  layout "frontend"

  def current_customer
    @current_customer ||= Customer.find(session[:customer_id]) if session[:customer_id]
  end

  def authorize
    if session[:auth] != true
      redirect_to login_path, :notice => "Not logged."
    end
  end

  def show
  end

  def edit
  end

  def update
    respond_to do |format|
      if current_customer.update_attributes(params[:current_customer])
        format.html { redirect_to view_path, notice: 'Customer was successfully updated.' }
        format.json { head :no_content }
      else
        format.html { render action: "edit" }
        format.json { render json: current_customer.errors, status: :unprocessable_entity }
      end
    end
  end

end

  match "view" => "logged_customer#show", :via => :get
  match "edit" => "logged_customer#edit", :via => :get
  match "edit" => "logged_customer#edit", :via => :put

    <%= form_for current_customer, :url => url_for(:controller => 'logged_customer', :action => 'edit'), :html => { :class => 'form-horizontal' } do |f| %>

<% if current_customer.errors.any? %>
  <div id="error_explanation">
    <div class="alert alert-error">
      The form contains <%= pluralize(current_customer.errors.count, "error") %>.
    </div>
    <ul>
    <% current_customer.errors.full_messages.each do |msg| %>
      <li> <%= msg %></li>
    <% end %>
    </ul>
  </div>
<% end %>

...

（：controller=>'logged_customer'，：action=>'edit'），：html=>{:class=>'form horizontal'}do | f |%> 表单包含。

... 我可以显示localhost:3000/视图，其中是编辑按钮。在localhost:3000/edit中，表单显示了自动填充的信息，一切看起来都很好。当我点击提交按钮时，我被重定向到相同的编辑自动填写表单，但没有任何错误？所以我想这是因为更新失败了，还有一个错误是它没有呈现错误。我做错了什么

我已经登录了customer\u controller.rb，因为customer\u controller.rb用于管理目的，并且处于授权之下

在Development.log上，我只有（看起来不错）

于2013-08-19 14:54:30+0200开始对127.0.0.1进行“编辑”
LoggedCustomerController处理#编辑为HTML
参数：{…}
在布局/前端（67.0ms）内呈现日志记录的用户/u customer/edit.html.erb
在89毫秒内完成200 OK（视图：33.0毫秒|活动记录：56.0毫秒）

好吧，在你的

表单上，你说这个动作是
编辑
动作，而这个动作应该是
更新

<%= form_for current_customer, 
  :url => url_for(:controller => 'logged_customer', :action => 'edit'), 
  :html => { :class => 'form-horizontal' } do |f| %>

嗯，在你的
表单上，你说这个动作是
编辑
动作，而这个动作应该是
更新

<%= form_for current_customer, 
  :url => url_for(:controller => 'logged_customer', :action => 'edit'), 
  :html => { :class => 'form-horizontal' } do |f| %>

更改路线（rails 3）：

更改路线（rails 4）：

更改您的表格：

<%= form_for current_customer, :url => url_for(:controller => 'logged_customer', :action => 'update'), :method => "patch", :html => { :class => 'form-horizontal' } do |f| %>
  <%= # your form fields %>
<% end %>

（：controller=>‘logged_customer’，：action=>‘update’，：method=>‘patch’，：html=>{:class=>‘form horizontal’}do | f |%>

谢谢，这很有效，我终于知道匹配和获取之间的区别：-）谢谢，这很有效，我终于知道匹配和获取之间的区别：-）
