设计after_sign_in_path_for会产生路由错误

如何解决设计after_sign_in_path_for会产生路由错误

|| 我正在尝试将登录的用户重定向到其个人资料页面，但出现以下错误。

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

这是我要遵循的指南。 https://github.com/plataformatec/devise/wiki/操作方法：-redirect-to-a-specific-page-on-successful-sign-in 在我的application_controller中，我已添加

def after_sign_in_path_for(resource)
  trooper_trooper_profile_path
end

耙道显示：

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\"}

知道为什么路线不匹配吗？

解决方法

您没有告诉您的路径助手要显示哪个士兵档案。尝试这样更改after_sign_in_path_for方法：

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