Dynamic fields creation and accessing data

Hi friends ,
I was trying this code and finding some errors.I am trying this to
implement dynamic creation of invoice items in invoices using AJAX
.Please go thru .

I added a partial ::
<% @invoiceitem = invoiceitem -%>
<%= text_field ‘invoiceitem’, ‘item_price’, ‘index’ =>
invoiceitem_counter %>
<%= text_field ‘invoiceitem’, ‘item_qty’, ‘index’ =>
Where are we initialising the counter? Please tell how is the first line
working .

In the rhtml file I have added :

<%= form_remote_tag(:update => "my_list",
                   :url => { :action => :add_new_item },
                   :position => "bottom" ) %>

        <%= submit_tag "Add New Item" %>
   <%= end_form_tag %>
  • Original item... please add more!
<%= submit_tag 'Update' %>
I have added like this for creating a dynamic generation of text boxes using ajax.

And in the controller class ,

def add_new_item

render(:partial => ‘invoiceitems’, :collection => @invoice_items)

def save_items

 @items = []
params[:invoiceitem].each do |key, item|
	@items = InvoiceItem.new(item)


Please help my in implementing this requirement .

Thanks and regards,
Naroor R…
