Rails 3破坏链接不起作用

Question

我的销毁链接不起作用。

我的索引视图：

<div id="konkurrancer"><%= render 'konkurrencer', :remote => true %></div><%= debug(params) %>

我的 konkurrencer 部分：

<% for konkurrancer in @konkurrancers %>    <%= link_to 'Destroy', [:admin, konkurrancer], :method => :delete %> <% end %>

我得到这个错误：

No route matches {:action=>"show", :controller=>"admin/konkurrancers", :id=>#<Konkurrancer id: 41, name: " Vind 16.000 kr., til Bilka, Føtex eller Netto

编辑视图中的错误：

ActionController::RoutingError in Admin/konkurrancers#index

Showing C:/Rails/konkurranceportalen/app/views/admin/konkurrancers/_konkurrencer.html.erb where line #59 raised:

No route matches {:action=>"show", :controller=>"admin/konkurrancers", :id=>#<Konkurrancer id: 41, name: " Vind 16.000 kr., til Bilka, Føtex eller Netto", banner1: "http://partner.smartresponse-media.com/42/1092/1210...", banner2: "http://partner.smartresponse-media.com/42/1092/1210...", vaerdi: 16000, note: "", udtraekkes: "2011-05-31 22:00:00", created_at: "2011-05-04 12:35:44", updated_at: "2011-05-05 14:55:35", cached_slug: "vind-16000-kr-til-bilka-f\xC3\xB8tex-eller-netto", tid: "4 min", form: "Quiz", rating_score: 5, ratings: 1, rating: 5, photo_file_name: nil, photo_content_type: nil, photo_file_size: nil, photo_updated_at: nil, photo2_file_name: nil, photo2_content_type: nil, photo2_file_size: nil, photo2_updated_at: nil, image_remote_url: "", image_remote_url_2: "">}

Extracted source (around line #59):

耙路线：

delete_multiple_admin_konkurrancers DELETE /admin/konkurrancers/delete_multiple(
.:format) {:action=>"delete_multiple", :controller=>"admin/konkurrancers"}
                admin_konkurrancers GET    /admin/konkurrancers(.:format)
          {:action=>"index", :controller=>"admin/konkurrancers"}
                                    POST   /admin/konkurrancers(.:format)

          {:action=>"show", :controller=>"admin/konkurrancers"}
                                    PUT    /admin/konkurrancers/:id(.:format)
          {:action=>"update", :controller=>"admin/konkurrancers"}
                                    DELETE /admin/konkurrancers/:id(.:format)
          {:action=>"destroy", :controller=>"admin/konkurrancers"}

我的路线文件：

namespace :admin do
resources :tags
resources :kategoris
 resources :konkurrancers do
      collection do
        delete :delete_multiple
      end
    end
resources :reklamers
   end 

Answer 1

如果您使用的是 RESTful 资源，请尝试以下操作：

<%= link_to 'Destroy', [:admin, konkurrancer], :method => :delete %>

Answer 2

您可能需要将其更改为：

<%= link_to 'Destroy', :action => 'destroy', :id => konkurrancer.id, :method => :delete %>

或者如果您使用 RESTful 路由，例如：

<%= link_to 'Destroy', delete_konkurrancer(:id => konkurrancer.id), :method => :delete %>

Answer 3

使用命名空间控制器和路由时，您必须使用命名空间模型才能使link_to帮助器正确地连接到 function。

当我为模型编写额外的管理页面时，我还在admin命名空间中生成了一些包装模型。

例如，在 app/models/admin/person.rb

class Admin::Person < Person    
end

使各种 forms 和链接更加简单。

Answer 4

如果是 RESTful 资源，请尝试以下操作：

{<%= link_to 'Destroy', [:admin, konkurrancer], :method => :delete %>}

并使用适当的 javascript 助手。

这是 rails 的 javascript-helper 的问题。 您需要适当地使用 rails.js。 如果你使用prototype.js，那么在rails.js中你需要原型助手方法，否则如果你使用jquery，那么你需要rails jquery helper 。
