将Rails 3.0升级到3.1时，路由停止工作 [英] Routes stopped working when upgrading Rails 3.0 to 3.1

问题描述

我将Ruby 1.8.7与Rails 3.1一起使用。我的应用程序在Rails 3.0中运行良好，但是当我将其升级到Rails 3.1.4时，我所有的URL帮助程序都崩溃了！

I am using Ruby 1.8.7 with Rails 3.1. My application worked fine in Rails 3.0 but when I bumped it up to Rails 3.1.4, all my url helpers broke!

在过去2天像疯子一样谷歌搜索之后，我已经放弃了，该寻求帮助了。我不认为问题出在我的routes.rb文件上，而是更多在视图/帮助器端。

After Googling like a mad man the past 2 days, I have given up and the time has come to seek help. I don't believe the problem is with my routes.rb file but something more on the view/helper side.

我的routes.rb中包含以下内容：

I have the following in my routes.rb:

resources :sessions

在我的主页视图中，我看到以下链接_to，该错误出错了：

In my homepage view I have the following link_to, which errors out:

<%= link_to "Login", new_session_path %>

当我进行耙路时，得到以下输出，因此路径存在：

When I do rake routes, I get the following output, so the path exists:

          sessions GET    /sessions(.:format)          {:controller=>"sessions", :action=>"index"}
                   POST   /sessions(.:format)          {:controller=>"sessions", :action=>"create"}
       new_session GET    /sessions/new(.:format)      {:controller=>"sessions", :action=>"new"}
      edit_session GET    /sessions/:id/edit(.:format) {:controller=>"sessions", :action=>"edit"}
           session GET    /sessions/:id(.:format)      {:controller=>"sessions", :action=>"show"}
                   PUT    /sessions/:id(.:format)      {:controller=>"sessions", :action=>"update"}
                   DELETE /sessions/:id(.:format)      {:controller=>"sessions", :action=>"destroy"}

当我在浏览器中转到/ sessions / new时，页面再次加载，日一条路由存在，但在基于_path的url上出错：

When I go to /sessions/new in my browser, the page loads so again, the route exists, but it errors out on a _path based url:

<%= form_tag sessions_path, :method => :post do -%>

我得到的错误如下：

ActionView::Template::Error (undefined local variable or method `sessions_path' for #<#<Class:0x109cb8900>:0x109cab840>):

由于路由确实存在，因此必须使用url_for帮助器。我还要寻找什么？

It has to be something with the url_for helper as the routes do exist. What else should I look for?

更新1：

我在application_helper.rb中添加了以下内容：

I added the following inside application_helper.rb:

include Rails.application.routes.url_helpers

现在，当我出现以下错误时：

Now when I get the following error:

In order to use #url_for, you must include routing helpers explicitly. For instance, `include Rails.application.routes.url_helpers

这不是我刚才所做的？

更新2：

以下是Mr.Yoshiji建议的工作：

The following worked as MrYoshiji suggested:

Rails.application.routes.url_helpers.sessions_path

更新3：

我通过删除供应商目录中的一些旧的Rails 2插件再次使session_path工作。

I got sessions_path working again by removing some old Rails 2 plugins in vendor directory.

推荐答案

删除了供应商/插件中的一些Rails 2插件就可以了。

Removed some Rails 2 plugins in vendor/plugins did the trick.
