Devise SessionsController的未定义方法`user_url':创建
问题描述:
我有设计宝石授权的用户模型。我想补充after_sign_in_path方法:Devise SessionsController的未定义方法`user_url':创建
# application_controller.rb
protected
# redirecting to appropriate url based on role
def after_sign_in_path_for(resource)
if current_user.has_role?(:admin)
dashboard_path
elsif current_user.has_role?(:student)
root_path
end
end
undefined method `user_url' for #<Devise::SessionsController:0x007fb89b5b00a8> Did you mean? course_url
authenticate :user do
resources :feeds, only: [:index]
resources :courses, only: [:index, :show]
# etc...
end
而且,这里是它指向我的代码:
if options.empty?
recipient.send(method, *args)
else
recipient.send(method, *args, options)
end
和日志的第一行:
actionpack (4.2.4) lib/action_dispatch/routing/polymorphic_routes.rb:220:in `polymorphic_method'
每当我赞扬after_sign_in_path_for我能够登录。如果我评论的after_sign_in_path_for内容,但保留为空after_sign_in_path_for方法,我也得到这个错误。
编辑:我测试了我不是也登录过,不只是没有重定向。我认为错误发生在调用after_sign_in_path_for之后,而不是在redirect_to或其他地方。可能它必须对资源做些事情。

确保你”已经有一个方法,你的AplicationController
像如下
def after_sign_in_path_for(resource)
resource.next_step
end
Next_step
是其创建过程中在记录中存储的属性,你可以决定硬代码在这里一些其他的路径。
答
def after_sign_in_path_for(resource)
if current_user.has_role?(:admin)
dashboard_path
elsif current_user.has_role?(:student)
root_path
else
root_path
end
end
尝试在代码中添加其他条件。这对我有效。我错过了这样的事情。
答
我敢肯定,错误必须已经解决,直到现在。今天我开始讨论它,为了提醒并让其他用户知道(如果有的话),我会在这里提供答案。
当您的应用重新定义after_sign_in_path_for
方法并返回nil
值时,会引发此错误。按我的最好的客人,所提供的片断
def after_sign_in_path_for(resource)
if current_user.has_role?(:admin)
dashboard_path
elsif current_user.has_role?(:student)
root_path
end
end
,因为没有任何的条件越来越满意,因此返回值是nil
被给了一个错误。为了避免这种情况,你总是可以添加一个else
条件,如果没有其他条件的话就会得到满足。因此,下面的代码段应该已经工作(并且将为其他用户工作)
def after_sign_in_path_for(resource)
if current_user.has_role?(:admin)
dashboard_path
elsif current_user.has_role?(:student)
root_path
else
some_other_path || root_path
end
end
希望这可以帮助别人。欢呼:)
你能否在after_sign_in中获得current_user? –
@ChakreshwarSharma,即使我评论after_sign_in_path_for的内容,我得到这个错误。 – yerassyl
删除方法的内容并写入logger.info(“current_user =”+ current_user.to_json)super,在这之后得到的输出是什么 –
