路轨上的红宝石-在_sign_in_path_for之后修改会产生路由错误

Question

我试图重定向登录到其配置文件页面的用户，但收到以下错误。

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

这是我要遵循的指南。https://github.com/plataformatec/devise/wiki/How-to:-重定向到特定页面成功登录

在我的application_controller中，我添加了

def after_sign_in_path_for(resource)
  trooper_trooper_profile_path
end

耙路显示：

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？

Answer 1

您没有告诉路径助手要显示哪个士兵配置文件。

尝试更改您的after_sign_in_path_for方法，从而：

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

Answer 2

您正在重定向到操作后
