的form_for与模块和命名空间

Question

我在财务模块后续机型：

class Finance::BillRec < ActiveRecord::Base 
    ... 
    has_many :bill_rec_offs, :dependent => :destroy 
    ... 
end 

class Finance::BillRecOff < ActiveRecord::Base 
    ... 
    belongs_to :bill_rec 
    ... 
end 

我对我的form_for这样做：

<%= form_for([@bill_rec, @bill_rec_off]) do |f| %> 
    ... 
<% end %> 

的routes.rb

namespace :finance do 
    resources :bill_recs do 
    resources :bill_rec_offs 
    end 
end 

并且错误：

undefined method `finance_bill_rec_finance_bill_rec_offs_path' for #<#<Class:0x000000070757e0>:0x0000000708bec8> 

但是，路线finance_bill_rec_bill_rec_off_path（@bill_rec_off）运作良好。

我怎样才能做一个form_for命名空间和嵌套路线与模块？

Answer 1

尝试

form_for([:finance, @bill_rec, @bill_rec_off]) 

，或者如果它不帮助

form_for([@bill_rec, @bill_rec_off], url: finance_bill_rec_bill_rec_offs_path(@bill_rec, @bill_rec_off))
