ruby-on-rails - Rails3 CMS舒适墨西哥沙发与omniauth路由不匹配

Question

我集成了comfortable-mexican-sofa CMS与我的Rails 3.0.9应用程序和omniauth 0.2.6就位。

博客方面一切正常。我可以登录 cms-admin，使用管理控制台，发布帖子并注销( cms-admin 有自己的身份验证系统，与我的应用程序不同......)，然后我可以浏览新帖子。

问题是我的应用程序的其余部分使用omniauth 对用户进行身份验证，当我注销/登录时，出现以下错误:

Started GET "/auth/github" for 127.0.0.1 at 2011-07-25 21:04:46 +0200
  Processing by CmsContentController#render_html as HTML
  Parameters: {"cms_path"=>"auth/github"}
  SQL (0.3ms)  SELECT COUNT(*) FROM "cms_sites"
  Cms::Site Load (0.3ms)  SELECT "cms_sites".* FROM "cms_sites" LIMIT 1
Completed 500 Internal Server Error in 156ms

NoMethodError (undefined method `gsub!' for nil:NilClass):

Answer 1

这是一个路由问题。

Omniauth 通过检测 404 错误页面来工作:

如果它与路由/auth/:provider 匹配，则它捕获请求并将其发送给提供商

...但是comfortable-mexican-sofa cms (如refinery和其他)，有一个catch all路由，这就是为什么请求从未返回omniauth可以检测到的404错误的原因。

在舒适的墨西哥沙发案例中，它会通过“cms_path”=>“auth/github”获取

NoMethodError in CmsContentController#render_html
undefined method `gsub!' for nil:NilClass

而不是正确的omniauth路径，应该如下所示:

Started GET "/" for 127.0.0.1 at 2011-07-25 22:27:26 +0200
  Processing by HomeController#index as HTML
Rendered home/index.html.haml within layouts/application (29.5ms)
Completed 200 OK in 44ms (Views: 42.8ms | ActiveRecord: 0.0ms)

Rendered home/index.html.haml within layouts/application (415.6ms)
Completed 200 OK in 890ms (Views: 428.6ms | ActiveRecord: 0.0ms)

我的案例的解决方案如下:

在app/controllers/errors_controller.rb中

class ErrorsController < ApplicationController
  def error
    render :file => "#{Rails.root}/public/404.html", :status => 404, :layout => false
  end
end

在 config/routes.rb 底部添加

匹配 '/auth/:provider' => 'errors#error'

...在 Omniouth 最后一条路线之后

`match "/auth/:provider/callback" => "sessions#create"`
