在具有devise gem的Rails 4中，覆蓋after_sign_in_path_for無效

Question

根據設計文檔，在ApplicationController中，“ 如何：成功登錄和注銷時重定向到特定頁面” ，即使在撬調試控制台中也無法到達時切換大小寫，它顯示'resource.class ==用戶為true '。 我不知道我錯過了Rails處理的哪一部分，任何提示將不勝感激！

# 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

Answer 1

你很親密 只需使用resource.class.name獲取資源類名稱，以便您可以將其與諸如'User'類的字符串進行比較，這不過是您的類名稱。

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

Answer 2

您可以通過創建從Devise::SessionsController繼承的SessionsController來解決。

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

像這樣在您的routes.rb指向它：

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