If I define a model like this

class Article

end

How can I retrieve articles without 'context' field loaded?

You can limit what is returned with select - Article.select('id, title') although there is no way that I am aware of to say 'all columns except this one' without explicitly listing them).

If you do this article.context would raise an error (MissingAttributeError if my memory is correct) - I think you'll have to reload the record if you do decide that you want to use that column for a particular instance
