ruby-on-rails - Rails 3 管理命名空间

Question

我正在尝试为 cms 创建一个管理后端。

所以我有一个站点模型、一个 SitesController 和一个 Admin:SitesController。

在/app/views/sites/show.html 和/app/views/admin/sites/index.html、new.html 等中

routes.rb

  namespace :admin do 
    resources :sites, :except => :show
  end

  match '/:slug' => 'sites#show'

编辑

日志输出

Rails 不会使用表单中的参数创建记录。有什么想法吗？

这些是方法和 View :

管理/站点#new

  def new
    @site = Site.new

    respond_to do |format|
      format.html # new.html.erb
    end
  end

管理/站点#create

定义创建 @site = Site.new(params[:site])

respond_to do |format|
  if @site.save
    format.html { redirect_to admin_sites_path, notice: 'Site was successfully created.' }
  else
    format.html { render action: "new" }
  end
end

admin/sites/_form

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

      <ul>
      <% @site.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>
  <div class="fields">
    <%= f.label :title %><br/>
    <%= f.text_field :title %>
  </div>
  <div class="fields">
    <%= f.label :content %><br/>
    <%= f.text_area :content %>
  </div>
  <div class="fields">
    <%= f.label :slug %><br/>
    <%= f.text_field :slug %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

Answer 1

您应该重定向到

 [:admin, :sites]

索引页

UPD

<%= form_for(@site, :url => [:admin, @site]) do |f| %>
