has_one嵌套路由和路由错误消息:"没有路由匹配[POST]"/ users/3/profiles""

Question

提交"创建我的个人资料"后发生错误

路由错误

没有路由匹配[POST]"/ users/3/profiles"

其次,我重新启动了webbrick cli ="rails s",输入"http:// localhost:3000/users/1/profile/new"后,我收到错误消息"undefined method`user_profiles_path'".显然,我使用了"resource:profile"非嵌套资源.我正在撕扯我的头发,这些错误发生了什么？

据我了解,rails无法知道form_for ([@user, @profile])(假设@profile是一条新记录)是要路由到,/users/:user_id/profile还是/users/:user_id/profiles用动词POST.一般来说,它将采用复数形式,因此您必须通过书写明确告诉它是否需要单数形式

form_for @profile, url: user_profile_path(@user)
