您希望在这里得到一些答案。我一遍又一遍地想到这一点,它正在杀了我。想要现在得到答案,我所发现的一切都比我目前的litle系统更复杂。问题如下。

首先是我的路线档案:

get 'admin' => 'admin#index'
  namespace "admin" do
  resources :products
end

我的管理产品控制器如下:

class Admin::ProductsController < ApplicationController
  # GET /products
  # GET /products.json
  def index
    @products = Product.all

    respond_to do |format|
     format.html # index.html.erb
     format.json { render json: @products }
   end
end

# GET /products/1
# GET /products/1.json
 def show
   @product = Product.find(params[:id])

   respond_to do |format|
     format.html # show.html.erb
     format.json { render json: @product }
   end
 end

 # GET /products/new
 # GET /products/new.json
  def new
    @product = Product.new

    respond_to do |format|
      format.html # new.html.erb
      format.json { render json: @product }
    end
 end

 # GET /products/1/edit
 def edit
    @product = Product.find(params[:id])
 end

  # POST /products
  # POST /products.json
  def create
    @product = Product.new(params[:product])

    respond_to do |format|
     if @product.save
       format.html { redirect_to @product, notice: 'Product was successfully created.' }
       format.json { render json: @product, status: :created, location: @product }
     else
       format.html { render action: "new" }
       format.json { render json: @product.errors, status: :unprocessable_entity }
     end
    end
   end

   # PUT /products/1
   # PUT /products/1.json
   def update
     @product = Product.find(params[:id])

     respond_to do |format|
      if @product.update_attributes(params[:product])
       format.html { redirect_to @product, notice: 'Product was successfully updated.' }
        format.json { head :ok }
     else
        format.html { render action: "edit" }
        format.json { render json: @product.errors, status: :unprocessable_entity }
      end
     end
    end

    # DELETE /products/1
    # DELETE /products/1.json
     def destroy
      @product = Product.find(params[:id])
      @product.destroy

     respond_to do |format|
        format.html { redirect_to products_url }
        format.json { head :ok }
     end
    end
   end

我的管理产品视图文件是标准文件,这里是_form,new,索引文件:

    New:


    <%= render 'form' %>

       <%= link_to 'Back', admin_products_path %>

     _form:
      <%= form_for [:admin, @product] do |f| %>
      <% if @product.errors.any? %>
        <div id="error_explanation">
          <h2><%= pluralize(@product.errors.count, "error") %> prohibited this product     from being saved:</h2>

          <ul>
            <% @product.errors.full_messages.each do |msg| %>
            <li><%= msg %></li>
           <% end %>
          </ul>
          </div>
          <% end %>

         <div class="field">
          <%= f.label :title %><br />
          <%= f.text_field :title %>
         </div>
         <div class="field">
            <%= f.label :description %><br />
            <%= f.text_area :description, rows: 6 %>
          </div>
           <div class="field">
            <%= f.label :image_url %><br />
            <%= f.text_field :image_url %>
           </div>
            <div class="field">
              <%= f.label :price %><br />
              <%= f.text_field :price %>
            </div>
             <div class="actions">
             <%= f.submit %>
           </div>
           <% end %>

     Index:
     <h1>Admin Listing products</h1>
      <table>
    <% @products.each do |product| %>
    <tr class="<%= cycle('list_line_odd', 'list_line_even') %>">

    <td>
        <%= image_tag(product.image_url, class: 'list_image') %>
    </td>

    <td class="list_description">
    <dl>
        <dt><%= product.title %></dt>
        <dd><%= truncate(strip_tags(product.description),
                length: 80) %></dd>
    </dl>
    </td>

    <td class="list_actions">
        <%= link_to 'Edit', edit_admin_product_path(product) %><br/>
        <%= link_to 'Destroy', admin_product_path(product),
            confirm: 'Are you sure?',
            method: :delete %>
    </td>
    </tr>
<% end %>
</table>
<br />
<%= link_to 'New product', new_admin_product_path %>

好的,我希望这是帮助我所需的所有信息。

这是一个问题:如果我去localhost:3000 / admin / products / new 我到表单创建一个新产品。但是,如果我填写表单,它将带我到以下localhost:3000 / product /:id。我希望它能重定向到管理/产品。

我一直告诉自己,它必须是管理产品控制器上“创建”程序中的redirect_to,但是尝试了一切并且它不起作用.....请帮助它是杀了我哈哈

JUst重定向到您的索引操作,而不是显示产品。这也适用于您的更新操作,如果他们还希望用户在更新产品时被重定向到索引页面。只需将redirect_to @product更改为redirect_to :action => 'index'

这不起作用,但这是一步一步的指南。 http://icebergist.com/posts/restful-admin-namespaced-controller-using-scaffolding
