Rails - Oct 2006 - updating multiple records in form

Hi. I have an app that has prodcts, which have many details.

I''m writing a view that allows the user to update the product info and
also info on each details record (number remaining in inventory, etc).
The form displays fine and populates w/ the detail records, and it
updates the product record. But it does not alter the detail record at
all. Suggestions?

Here''s the controller...

	def edit
  		if request.get?
      		@product = Product.find(params[:id], :order=>''gender,
size'',
:include=>''details'' )

  		else
    		@product = product.find(params[:id])
    		if @product.update_attributes(params[:product])
      			flash[:notice] = ''product was successfully updated.''
      			redirect_to :action => ''show'', :id => @product
    		else
      			render :action => ''edit''
    		end
  		end
	end


And a snippet of the view

<% for    @detail in @product.details %>
 
<td><%= text_field ("detail[]", "remaining")
%></td>
 <% end %>

It looks like you''re wanting @product.update to automatically alter the
associated record based on the contents of params.

As far as I know, rails won''t do this out of the box. - You''ll
have to
do it manually, either in the controller or the model.
