Question

首先发布这里...做ROR教程并找到关于这个问题的类似问题......但当然没有成功。无论如何，在教程之后一切正常，除非点击这个链接我得到错误The action 'edit1' could not be found for SubjectsController ...非常感谢任何帮助！我自己和教程都使用相同版本... 4.0。

SubjectsController：

class SubjectsController < ApplicationController

  layout false

  def index
    @subjects = Subject.sorted
  end

  def show
    @subject = Subject.find(params[:id])
  end

  def new
    @subject = Subject.new({:name => "Default"})
  end

  def create
    # Instantiate a new object using form parameters
    @subject = Subject.new(subject_params)
    # Save the object
    if @subject.save
      # If save succeeds, redirect to the index action
      redirect_to(:action => 'index')
    else
      # If save fails, redisplay the form so user can fix problems
      render('new')
    end
  end

  def edit
    @subject = Subject.find(params[:id])
  end

  def update
    # Find an existing object using form parameters
    @subject = Subject.find(params[:id])
    # Update the object
    if @subject.update_attributes(subject_params)
      # If update succeeds, redirect to the index action
      redirect_to(:action => 'show', :id => @subject.id)
    else
      # If update fails, redisplay the form so user can fix problems
      render('edit')
    end
  end

  def delete
    @subject = Subject.find(params[:id])
  end

  def destroy
    subject = Subject.find(params[:id]).destroy
    redirect_to(:action => 'index')
  end


  private

    def subject_params
      # same as using "params[:subject]", except that it:
      # - raises an error if :subject is not present
      # - allows listed attributes to be mass-assigned
      params.require(:subject).permit(:name, :position, :visible)
    end

end

Edit.html

    <%= link_to("<< Back to List", {:action => 'index'}, :class => 'back-link') %>

<div class="subjects edit">
  <h2>Update Subject</h2>

  <%= form_for(:subject, :url => {:action => 'update', :id => @subject.id}) do |f| %>

    <table summary="Subject form fields">
      <tr>
        <th>Name</th>
        <td><%= f.text_field(:name) %></td>
      </tr>
      <tr>
        <th>Position</th>
        <td><%= f.text_field(:position) %></td>
      </tr>
      <tr>
        <th>Visible</th>
        <td><%= f.text_field(:visible) %></td>
      </tr>
    </table>

    <div class="form-buttons">
      <%= submit_tag("Update Subject") %>
    </div>

  <% end %>
</div>

路由文件

SimpleCms::Application.routes.draw do


  root "demo#index"

  #get "demo/index"
  match ':controller(/:action(:id))', :via => [:get, :post]

除此之外，我在Chrome和Windows 7上。

Code for Show link:

    <%= link_to("<< Back to List", {:action => 'index'}, :class => 'back-link') %>

<div class="subjects show">
  <h2>Show Subject</h2>

  <table summary="Subject detail view">
    <tr>
      <th>Name</th>
      <td><%= @subject.name %></td>
    </tr>
    <tr>
      <th>Position</th>
      <td><%= @subject.position %></td>
    </tr>
    <tr>
      <th>Visible?</th>
      <td><%= @subject.visible ? 'true' : 'false' %></td>
    </tr>
    <tr>
      <th>Created</th>
      <td><%= @subject.created_at %></td>
    </tr>
    <tr>
      <th>Updated</th>
      <td><%= @subject.updated_at %></td>
    </tr>
  </table>

</div>



Code for delete link:

        <%= link_to("<< Back to List", {:action => 'index'}, :class => 'back-link') %>

<div class="subjects delete">
  <h2>Delete Subject</h2>

  <%= form_for(:subject, :url => {:action => 'destroy', :id => @subject.id}) do |f| %>

    <p>Are you sure you want to permanently delete this subject?</p>

    <p class="reference-name"><%= @subject.name %></p>

    <div class="form-buttons">
      <%= submit_tag("Delete Subject") %>
    </div>

  <% end %>
</div>

Answer 1

您的控制器包含编辑操作，但不包含edit1。 edit1是由于路由设置无效而与参数连接的操作的结果。在您的路线配置中，缺少斜线/

应该是这样的

 match ':controller(/:action(/:id))', :via => [:get, :post]
                             ^
                             |

Answer 2

在＆＃39;匹配＆＃39;中添加斜杠Mladen建议的路线将解决您的直接问题。但是，不再建议使用该默认路由;最好明确你的路线。

这将为您提供＆＃39;标准＆＃39; REST-ful路线，取代＆＃39;匹配＆＃39;路线档案中的路线：

resources :subjects

如果您真的使用“删除”＆＃39;在你的控制器中你需要一个＆＃39;成员＆＃39;添加该条目的条目，但通常只有一个链接在节目和/或编辑表单上才能直接进入＆＃39; destroy＆＃39;删除记录的行动;不确定为什么你需要单独删除＆＃39;图。

无法找到SubjectsController的动作'edit1'
