轨道上的红宝石 - 未知操作 找不到 Devise：：OmniauthCallbacksController 的操作'linkedin'

Question

我试图在我的Rails应用程序中实现开放授权，以便用户可以使用他们的LinkedIn帐户登录。当我点击链接进入LinkedIn授权页面，然后确认我的LinkedIn凭据时，我在应用程序中得到一个错误:

Unknown action
The action 'linkedin' could not be found for Devise::OmniauthCallbacksController

我几乎肯定问题在于我的路由文件。许多教程都要求添加以下行:

devise_for :users, :controllers => { :omniauth_callbacks => "omniauth_callbacks" }

然而，我已经有了这一行自定义的设计登录:

devise_for :users, :controllers => { :registrations => "registrations" } 

我试着切换它们，但没有工作(如我所料)。有没有办法把这两个表述结合起来?

谢谢!

omniauth_callbacks_controller问题:The action 'linkedin' could not be found for OmniauthCallbacksController

class OmniauthCallbacksController < ApplicationController
    class OmniauthCallbacksController < Devise::OmniauthCallbacksController   
def linkedin
    auth = env["omniauth.auth"]
    @user = User.connect_to_linkedin(request.env["omniauth.auth"],current_user)
    if @user.persisted?
      flash[:notice] = I18n.t "devise.omniauth_callbacks.success"
      sign_in_and_redirect @user, :event => :authentication
    else
      session["devise.linkedin_uid"] = request.env["omniauth.auth"]
      redirect_to new_user_registration_url
    end
  end
end
end

Answer 1

使用

devise_for :users, :controllers => { :registrations => "registrations",  :omniauth_callbacks => "omniauth_callbacks"} 

这意味着您正在定制设计的RegistrationsController和OmniauthCallbacksController。

例如:

class OmniauthCallbacksController < Devise::OmniauthCallbacksController
...
end

和

class RegistrationsController < Devise::RegistrationsController
...
end
