[Rails] multiple input record, single model (without nested model)

[just-a-noob]

hello everyone, I'm new to rails 
i have some question thats been quite a headache to me, so here it is:

for example i have this controller & view

controller

class OrdersController < ApplicationController


  def new
  @Order = Order.new
  end 
      
  def create
    @Order = Order.new(params[:order])
    if @Order.save
      flash[:notice] = "Successfully created order."
      redirect_to @Order
    else
      render :action => 'new'
    end
  end

 

View 

<% title "Menu Order" %>
<%= form_for @Order do |f| %>
  <%= f.error_messages %>

<div id="form-order">
  <p>
    <%= f.label :name%><br />
    <%= f.text_field :name, %>
  </p>
  <p>
    <%= f.label :menu_order %><br />
    <%= f.text_field :menu_order  %>
  </p>   
</div>
  <%= f.submit %>

my question is :
before displaying the form above, I want to have a text_field_tag that specify how many forms (roughly said, duplicate the form div) I want to generate based on count, and then insert the data to the database simultaneously,
This is similar to ryan bates railscasts but they don't meet my requirement, i want to use single model, not nested.
the idea is to speed things up, so that the user don't have to input the data only one at a time, but multiple record at single submit
how do i do that?
Any suggestions and solutions  will be much appreciated 
thanks before :)

Rails (and Ruby) expect instance variables to begin with a lower-case
letter. This may be working for you anyway, but I thought I'd point
out that @Order and @order **mean** fundamentally different things.

You're going to need to shift your new and create methods around to
create and expect an array of orders rather than a single order. This
may be very difficult, since it is essentially swimming upstream
against Rails' conventions. You might get a lot more mileage out of
creating a new wrapper model, like Cart, and having it
accept_nested_attributes_for :orders. You can follow the Railscast
that way, which works most excellently. (There are a couple of books
when you build it in Rails 3, mostly to do with the JavaScript stuff
because you'll get double-escaped output if you follow it precisely.
Remember that h is implicit in erb templates now, and you have to mark
the stuff you don't want escaped with .html_safe.)
