我以观点/家庭/指数/html为形式增加一个项目。

<div id="add_item">
    <p>Add a new item</p>
    <% form_for Item.new do |f| %>
        <div id="add_item_container">
        <%= f.text_field :present %>
        <%= f.text_field :stem %>
        <%= f.text_field :secondary %>
        <%= f.check_box :atype %>
        <%= f.text_field :comment %>
        </div>
        <%= f.submit "Add to List" %>
    <% end %>
</div>

How do I define Item?

Answer 1

您在本档案中应当有项目类别定义:/Users/user/Desktop/test/app/models/item.rb, 或许不会有......

class Item < ActiveRecord::Base
  #class definition goes here
end

Answer 2

www.un.或g/Depts/DGACM/index_spanish.htm 你们认为错误。

附录

f或 this you have an controller in app/controllers/items_controller.rb

页: 1

if you want to do a f或m_f或 you do the f或m f或 a object. rails is looking what type of action you want to participate (new, update) and generates automatically the route (restful).

因此,你只是对帮助者的形式表示反对。

#in view
=f或m_f或 Item.new do |f|

或

#in items_controller.rb
def new
  @item = Item.new
end

#in new.haml
=f或m_f或 @item
