Rails的嵌套資源問題

Question

我有一對夫婦的資源，一個grant_application的，並且其與一個HAS_ONE

class GrantApplication < ActiveRecord::Base 
    has_one :household, :dependent => :destroy 
end 

class Household < ActiveRecord::Base 
    belongs_to :grant_application 
end 

..和我也用下面的路由相關家庭..

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

但是，試圖創建/ grant_applications/1 /戶/形式新

使用時，我有真正的問題

<% form_for([:grant_application, @household]) do |f| %> 

返回一個錯誤：

undefined method 'grant_households_path' for #<ActionView::Base:0x23eda44> 

任何想法？

Answer 1

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