Rails嵌套资源问题

我有一些资源,一个grant_application和一个与has_one相关的家庭

class GrantApplication  :destroy end class Household < ActiveRecord::Base belongs_to :grant_application end 

..我也使用以下路线..

 map.resources :grant_applications do |grant| grant.resource :household end 

但是,在尝试为/ grant_applications / 1 / household / new创建表单时,我遇到了实际问题

运用

  

返回错误:

 undefined method 'grant_households_path' for # 

有任何想法吗?

 <% form_for(@household, :url => grant_application_household_path(@grant) ) do |f| %>
