我在我的routes.rb中嵌套了这样的资源 – (
my rake:routes gist)
@H_404_2@namespace(:admin) do
resources :restaurants do
resources :menus
resources :menu_items
end
end
在控制器中：
@H_404_2@def new @restaurant = Restaurant.find(params[:restaurant_id]) @menu_item = @restaurant.menu_items.build end尝试创建一个新的MenuItem(动作#new),由url：http://127.0.0.1:3001/admin/restaurants/1/menu_items/new我得到错误：
@H_404_2@NoMethodError in Admin/menu_items#new Showing /home/fps/workspace3/peded/app/views/admin/menu_items/_form.html.erb where line #1 raised: undefined method `admin_menu_items_path' for #<#<Class:0xb6582d78>:0xb6581f2c> Extracted source (around line #1): 1: <%= form_for @menu_item do |f| %> ...如何使此表单正常工作？它是由一个漂亮的：脚手架创建的
UPDATE
我也在_form中尝试过：
@H_404_2@<%= form_for [:restaurant,@menu_item] do |f| %>但结束了类似的错误：
@H_404_2@Showing /home/fps/workspace3/peded/app/views/admin/menu_items/_form.html.erb where line #1 raised: undefined method `restaurant_admin_menu_items_path' for #<#<Class:0xb68162b0>:0xb6813dd0> Extracted source (around line #1): 1: <%= form_for [:restaurant,@menu_item] do |f| %我应该提交错误吗？
解决方法
我认为问题是形式.这对我有用：
@H_404_2@<%= form_for(@menu_items,:url => restaurant_menu_items_path(@menu_items.restaurant)) do |f| %>
