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/… Application Trace | Framework Trace | Full Trace /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.13.2/lib/active\_record/base.rb:1498:in `method_missing' /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/base.rb:694:in`erase\_render\_results’ /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action\_controller/base.rb:712:in `erase_results' /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/rescue.rb:28:in`rescue\_action’ /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action\_controller/rescue.rb:108:in `perform_action' /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/base.rb:369:in`process\_without\_session\_management\_support’ /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action\_controller/session\_management.rb:116:in `process' /usr/local/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/dispatcher.rb:38:in`dispatch’ /usr/local/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/webrick\_server.rb:117:in `handle_dispatch' /usr/local/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/webrick_server.rb:83:in`service’ /usr/local/lib/ruby/1.8/webrick/httpserver.rb:104:in `service' /usr/local/lib/ruby/1.8/webrick/httpserver.rb:65:in`run’ /usr/local/lib/ruby/1.8/webrick/server.rb:173:in `start_thread' /usr/local/lib/ruby/1.8/webrick/server.rb:162:in`start\_thread’ /usr/local/lib/ruby/1.8/webrick/server.rb:95:in `start' /usr/local/lib/ruby/1.8/webrick/server.rb:92:in`start’ /usr/local/lib/ruby/1.8/webrick/server.rb:23:in `start' /usr/local/lib/ruby/1.8/webrick/server.rb:82:in`start’ /usr/local/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/webrick\_server.rb:69:in `dispatch' /usr/local/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/commands/servers/webrick.rb:59 /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in`require’ /usr/local/lib/ruby/gems/1.8/gems/activesupport-1.2.5/lib/active\_support/dependencies.rb:214:in `require' /usr/local/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/commands/server.rb:28 /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in`require’ /usr/local/lib/ruby/gems/1.8/gems/activesupport-1.2.5/lib/active\_support/dependencies.rb:214:in `require’ ---

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. ---

Shouldn’t you also be inheriting from ActionController and not ApplicationController? Have a look at the ActionController class ([http://rubyonrails.org/api/classes/ActionController/Base.html](http://rubyonrails.org/api/classes/ActionController/Base.html)). 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 =) ---

> 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 ---

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