ruby-on-rails - RoR : nested namespace routes, 未定义方法错误

Question

我正在开发一个新的 Rails 应用程序的管理部分，我正在尝试设置一些路线以“正确”地做事。我有以下 Controller :

class Admin::BlogsController < ApplicationController
  def index
    @blogs = Blog.find(:all)
  end

  def show
    @blog = Blog.find(params[:id])
  end

  ...
end

在 routes.rb 中:

map.namespace :admin do |admin|
  admin.resources :blogs
end

在 views/admin/blogs/index.html.erb 中:

<% for blog in @blogs %>
  <%= link_to 'Delete', admin_blog(blog), :method => :delete
<% end %>

我已验证路由存在:

admin_blogs GET /admin/blogs {:action => "index", :controller=>"admin/blogs"}
admin_blog  GET /admin/blogs/:id {:action => "show", :controller => "admin/blogs"}
....

但是当我尝试查看 http://localhost:3000/admin/blogs我得到这个错误:

undefined method 'admin_blog' for #<ActionView::Base:0xb7213da8>

我哪里错了，为什么？

您的删除链接应以 _path 结尾:

<%= link_to 'Delete', admin_blog_path(blog), :method => :delete %>
