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.
