我有用于设计授权的用户模型。我想添加after_sign_in_path方法:
# 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
&#13;
authenticate :user do
resources :feeds, only: [:index]
resources :courses, only: [:index, :show]
# etc...
end
&#13;
这也是它给我的代码:
if options.empty?
recipient.send(method, *args)
else
recipient.send(method, *args, options)
end
&#13;
和第一行日志:
actionpack (4.2.4) lib/action_dispatch/routing/polymorphic_routes.rb:220:in `polymorphic_method'
&#13;
每当我推荐after_sign_in_path_for我能够登录。如果我评论after_sign_in_path_for的内容但留下空的after_sign_in_path_for方法,我也会收到此错误。
编辑:我测试过我还没有登录,而不仅仅是没有重定向。我认为错误发生在调用after_sign_in_path_for,而不是在redirect_to或其他什么。可能它必须对资源做一些事情。EDIT2:这是我的佣金路线:

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else条件。这对我有用。我错过了这样的事情。

我确定错误必须一直解决到现在为止。今天我为了提及并让其他用户知道(如果有的话),我会在这里提供答案。
在您的应用中重新定义after_sign_in_path_for
方法并返回nil
值时,会抛出此错误。根据我最好的客人,提供的代码段
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
发出错误,因为没有任何条件得到满足,因此返回值为nil
。为了避免这种情况,您可以随时添加else
条件,如果没有其他条件,则会满足该条件。因此,下面的代码片段应该有效(并且适用于其他用户)
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
希望这有助于某人。干杯:)

确保您的AplicationController
上有一个方法,如下所示
def after_sign_in_path_for(resource)
resource.next_step
end
Next_step
是在创建过程中存储在记录中的属性,您可以决定在此处硬编码其他路径。
