Question

我在Rails 3中使用Devise。如果未登录的用户点击链接，我已使用before_filter :authenticate_user!重定向登录。这有效，但登录后，它会重定向回主页。相反，我想重定向到用户在重定向到登录页面之前单击的链接。这是我的代码：

application_controller.rb

class ApplicationController < ActionController::Base
  protect_from_forgery
  before_filter :authenticate_user!
  layout :layout_by_resource

  def after_sign_in_path_for(resource_or_scope)
    if resource_or_scope.is_a?(User)
      if current_user.admin?
        admin_event_types_path
      else
        home_path
      end
    else
      super
    end
  end
  ..
  ..
end

user.rb

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable, 
         :token_authenticatable
  ..
  ..
end

更新

我使用@dreamfall的回答尝试了这个，但它没有按预期重定向。

def after_sign_in_path_for(resource_or_scope)
  if resource_or_scope.is_a?(User)
    if current_user.admin?
      stored_location_for(resource_or_scope) ? stored_location_for(resource_or_scope) : admin_event_types_path 
    else
      stored_location_for(resource_or_scope) ? stored_location_for(resource_or_scope) : home_path
    end
  else
    super
  end
end

Devise中是否有内置配置？如果没有，我将如何解决这个问题？我应该在哪里更改代码？

Answer 1

Devise提供了在登录后重定向到存储在会话网址中的功能。在stored_location_for(resource_or_scope)方法中使用after_sign_in_path_for(resource_or_scope)方法。

Answer 2

我遇到了同样的问题，我解决了这个问题：

before_action :store_location

  def after_sign_in_path_for(*)
    session[:previous_url] || root_path
  end

  private

  def store_location
    # store last url - this is needed for post-login redirect to 
    whatever the user last visited.
    return unless request.get?
    if (request.path != "/users/sign_in" &&
        request.path != "/users/sign_up" &&
        request.path != "/users/password/new" &&
        request.path != "/users/password/edit" &&
        request.path != "/users/confirmation" &&
        request.path != "/users/sign_out" &&
        !request.xhr?) # don't store ajax calls
      session[:previous_url] = request.fullpath
    end
  end

这基本上是拦截所有获取请求并将URL保存在用户的会话上。在您登录后如果保存了previous_url，它将被正确重定向。

设计 - 如果用户未登录，则重定向到登录后单击的用户
