Heroku recognize non exist model
===

I tried to upload my rails3.2 app on Heroku.
I followed the instruction on Heroku and could uploaded that.

After I opened the app, I got error.
I ran "heroku logs" and got 

		2012-07-21T19:07:01+00:00 app[web.1]: => Booting Thin
		2012-07-21T19:07:01+00:00 app[web.1]: => Rails 3.2.6 application starting in production on http://0.0.0.0:34125
		2012-07-21T19:07:01+00:00 app[web.1]: => Call with -d to detach
		2012-07-21T19:07:01+00:00 app[web.1]: Exiting

		2012-07-21T19:07:01+00:00 app[web.1]: /app/vendor/bundle/ruby/1.9.1/gems/activesupport-3.2.6/lib/active_support/dependencies.rb:251:in `require':   /app/app/models/question.rb:2: syntax error, unexpected '\n', expecting tASSOC (SyntaxError)

This log says I have SyntaxError in 'question.rb', but I've already deleted that model before. So, it means Heroku recognized non exist model.

I tried "heroku pg:reset SHARED_DATABASE" and "bundle exec rake db:drop:all"
But Heroku still mis-recognize the model.

How can I fix this.
