Question

我正在使用https://github.com/apokalipto/devise_saml_authenticatable在Ruby on Rails应用程序中通过SAML对Okta实现登录。

使用上述说明设置示例应用程序后，尝试导航到/ users / saml / log_in时出现以下错误

ActionController::RoutingError (uninitialized constant SamlSessionsController):

activesupport (5.1.6) lib/active_support/inflector/methods.rb:269:in `const_get'
activesupport (5.1.6) lib/active_support/inflector/methods.rb:269:in `block in constantize'

actionpack (5.1.6) lib/action_dispatch/routing/mapper.rb:46:in `serve'
actionpack (5.1.6) lib/action_dispatch/journey/router.rb:50:in `block in serve'

不确定导致上述错误的原因。我确保gem是Gemfile的一部分并已安装。

还有什么可以研究的吗？

我能够解决这个问题。这是由于我的路线配置错误造成的。导致该问题的路由配置如下：

devise_scope :user do
    scope "users", controller: 'saml_sessions' do
      get :new, path: "saml/sign_in", as: :new_user_sso_session
      post :create, path: "saml/auth", as: :user_sso_session
      get :destroy, path: "sign_out", as: :destroy_user_sso_session
      get :metadata, path: "saml/metadata", as: :metadata_user_sso_session
      match :idp_sign_out, path: "saml/idp_sign_out", via: [:get, :post]
    end
  end

然而，正确的配置应该是：

devise_scope :user do
    scope "users", controller: 'devise/saml_sessions' do
      get :new, path: "saml/sign_in", as: :new_user_sso_session
      post :create, path: "saml/auth", as: :user_sso_session
      get :destroy, path: "sign_out", as: :destroy_user_sso_session
      get :metadata, path: "saml/metadata", as: :metadata_user_sso_session
      match :idp_sign_out, path: "saml/idp_sign_out", via: [:get, :post]
    end
  end

注意，控制器应该是＆＃39; devise/saml_sessions＆＃39;。

在这次改变之后，我能够成功地继续前进。

设计：devise_saml_authenticatable - 未初始化的常量SamlSessionsController
