I have a model Area which has_many Streets. The Area has a couple of attributes of its own but mostly I want to be able to add/delete/update Streets for a particular Area, but all on one page rather than having a separate view for editing a Street. I've managed to get a form displayed with a row for each Street already assigned to the Area by using form fields with street[id][name], street[id][num_houses] etc. But when I send the form I don't know how to get any validation errors reported. Errors on Area are nicely displayed with the red outlines - I think this is thanks to <%= error_messages_for 'area' %> being included in the view. Can I get this to work for the multiple Street input fields as well? I've tried <%= error_messages_for 'street' %> (You have a nil object when you didn't expect it! You might have expected an instance of ActiveRecord::Base. The error occured while evaluating nil.errors) and <%= error_messages_for 'street' %> (`@street' is not allowed as an instance variable name) def update_area @area = Area.find(params[:id]) @streets = @area.streets unless params[:street].nil? Street.update(params[:street].keys, params[:street].values) end if @area.update_attributes(params[:area]) flash[:notice] = 'Area was successfully updated.' redirect_to :action => 'edit_area', :id => @area else render :action => 'edit_area' end end Thanks so much in advance for any suggestions.

In fact, it is highly recommended that you use your own method or replace error_messages_for because it is so ugly (imho). To answer your question, though, see http://www.ruby-forum.com/topic/ 52143. The topic is closely related, and then goes off-topic a bit towards your direction, so keep reading. Duane J. (canadaduane) http://blog.inquirylabs.com/
