Rails 3.1rc5 index_path 未定义方法

Question

我被这个愚蠢的表单阻止：

我有一个 mn 关系：

class Elementtype < ActiveRecord::Base

  has_many :elementtypeproperties

class Propertytype < ActiveRecord::Base

  has_many :elementtypeproperties


class Elementtypeproperties < ActiveRecord::Base

  belongs_to :elementtype
  belongs_to :propertytype

我创建了这个表单：

<%= simple_form_for @elementtypeproperty  do |form| %>


    <%=form.collection :elementtype_id%>
    <%=form.collection :propertytype_id%>

    <%= form.button :submit %>



<% end %>

包含在此视图中：

<h1>New elementtypeproperty</h1>

<%= render 'form' %>

<%= link_to 'Back', elementtypeproperties_path %>

当我尝试打开该页面时，我收到以下消息：

ActionView::Template::Error (undefined method `elementtypeproperties_index_path' for #<#<Class:0x000001010b51d8>:0x000001010a5fa8>):
    1: <%= simple_form_for @elementtypeproperty  do |form| %>
    2: 
    3: 
    4:     <%=form.collection :order_id%>
  app/views/elementtypeproperties/_form.html.erb:1:in `_app_views_elementtypeproperties__form_html_erb__3568906133403572328_2153973000'
  app/views/elementtypeproperties/new.html.erb:3:in `_app_views_elementtypeproperties_new_html_erb__1519898890038681767_2154367600'
  app/controllers/elementtypeproperties_controller.rb:29:in `new'

出了什么问题？谢谢！！！

解决了，由于迁移错误，我的模型是复数的。
