Question

在ApplicationController中，根据设计文档How To: Redirect to a specific page on successful sign in and sign out，无法访问案例切换，即使在pry调试控制台中，也显示'resource.class == User is true'。我不知道我错过了Rails处理的哪个部分，任何提示都将受到赞赏！

# ApplicationController.rb
class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception


  protected
  def after_sign_in_path_for(resource)
    # check for the class of the object to determine what type it is
    binding.pry
    case resource.class
    when User
      puts "user redirect ==== "
      return session.delete(:return_to) || current_user_path
    else
      puts "super call ....."
      super
    end
  end
end

Answer 1

你非常接近。只需要使用resource.class.name获取资源类名称，以便您可以将其与'User'之类的字符串进行比较，而def after_sign_in_path_for(resource) # check for the class of the object to determine what type it is binding.pry case resource.class.name #=>this would return the class name i.e 'User' when 'User' puts "user redirect ==== " return session.delete(:return_to) || current_user_path else puts "super call ....." super end end只是您的类名。

您可以通过创建继承自SessionsController。

的Devise::SessionsController来解决此问题

class SessionsController < Devise::SessionsController
  skip_before_filter :authenticate_user!

  def create
    user = User.find_for_database_authentication(email: params[:session][:email])

    if user && user.valid_password?(params[:session][:password])
      sign_in user
      redirect_to session.delete(:return_to) || '/authorized'
    else
      redirect_to '/sign_in'
    end
  end

  def destroy
    sign_out :user
    redirect_to '/signed_out'
  end
end

在你的routes.rb内指向它：

devise_for :users, controllers: {sessions: 'sessions'}

在带有设计gem的Rails 4中，覆盖after_sign_in_path_for无效
