Hey guys, I'm trying to work my way through the Ruby on Rails tutorial building CRUD actions using scaffold based on a single database table. the "list" action seems to work well, but all other actions result in errors. See trace below .. I am only 2 hours into my Ruby (rails) experience and I have no idea how to track down this bug. Here's the top part of my ResponseController code: class ResponsesController < ApplicationController def index list render :action => 'list' end def list @response_pages, @responses = paginate :responses, :per_page => 10 end def show @response = Response.find(params[:id]) end def new @response = Response.new end Any help appreciated! Thanks! undefined method `body=' for #<Response:0xb756fed8> RAILS_ROOT: script/../config/..

If I had this error, I'd guess that I don't have the attribute "body" in my "responses" table. Though, I don't know the particulars of your setup, so it could be many things. However, please note that scaffolding is not the preferred way to learn Rails. And, secondly, there is a rails dedicated group that is probably a better place for rails questions. But, anyhow, goodluck with it! -hampton.

> > end > > Hi, My guess is that "response" is something special in Rails (so is "request" if I remember correctly). You are probably overwriting a Rails instance variable... Try renaming @response to something else. It might even be your "Response" model that's confusing Rails: maybe there is a Response class in Rails. Try renaming it to something else... I hope this will help... Guillaume

Shouldn't you also be inheriting from ActionController and not ApplicationController? Have a look at the ActionController class (http://rubyonrails.org/api/classes/ActionControlle...). I've always thought that ApplicationController was a top-level abstract? Thanks, Jeff (Oh, hi! I don't post much, but I enjoy reading what everyone else does =)

Thanks, Guillaume. This was the problem. I renamed my controller and things started working as they were designed. Thankyou, na
