NameError on accessing Active Record from the controller with Rails 2.0.2

I get following error on accessing ActiveRecord from the controller,

log\development.log

What exactly is your Question? Another model in your application? From
the looks of it, Rails doesn't know what a Question is...

Thanks for the reply. It helps to figure out the issue.

It was the model generation mistake. I have generated with model name in plural.

Thanks again.
