Ruby on rails 在路径中设计后符号以产生路由错误

我正在尝试将登录到其配置文件页面的用户重定向，但出现以下错误

No route matches {:action=>"create", :controller=>"trooper_profiles"}

这是我遵循的指南。

在我的应用程序中，我添加了

def after_sign_in_path_for(resource)
  trooper_trooper_profile_path
end

Rake routes显示：

trooper_trooper_profile POST   /troopers/:trooper_id/trooper_profile(.:format)      {:action=>"create", :controller=>"trooper_profiles"}
new_trooper_trooper_profile GET    /troopers/:trooper_id/trooper_profile/new(.:format)  {:action=>"new", :controller=>"trooper_profiles"}
edit_trooper_trooper_profile GET    /troopers/:trooper_id/trooper_profile/edit(.:format) {:action=>"edit", :controller=>"trooper_profiles"}
GET    /troopers/:trooper_id/trooper_profile(.:format)      {:action=>"show", :controller=>"trooper_profiles"}
PUT    /troopers/:trooper_id/trooper_profile(.:format)      {:action=>"update", :controller=>"trooper_profiles"}
DELETE /troopers/:trooper_id/trooper_profile(.:format)      {:action=>"destroy", :controller=>"trooper_profiles"}

你知道为什么路线不匹配吗？

你没有告诉你的路径助手要显示哪一个骑兵档案

尝试在方法的路径中签名后更改您的：

def after_sign_in_path_for(resource)
  trooper_trooper_profile_path(resource) # Note presence of 'resource'
end

---

您正在重定向到post action

不确定这是否只是我，但我必须将其放在application_helper.rb中，而不是application_controller.rb中。文档建议放入控制器，但在对路径进行签名之后，实际上是一个助手，而不是控制器方法。
