Ruby on rails 在带有Desive gem的Rails 4中，在路径中签名后覆盖无效

在ApplicationController中，根据Desive文档，当无法达到case开关时，即使在pry调试控制台中，它也会显示“resource.class==User is true”。我不知道我错过了Rails处理的哪一部分，任何提示都将不胜感激

# 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

#ApplicationController.rb
类ApplicationController

你已经很接近了。只需使用

resource.class.name

获取资源类名，这样您就可以将其与字符串（例如

'User'

）进行比较，该字符串只不过是您的类名

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

您可以通过创建继承自

designe:：sessioncontroller

的

sessioncontroller

来解决问题

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

非常感谢。我认为如果你能解释一下定制SessionController而不是在路径中签名后重写ApplicationController背后的想法，你的答案会更好。谢谢！我认为如果你能解释一下定制SessionController背后的想法，而不是在路径中签名之后覆盖ApplicationController，你的答案会更好。
