Rails 3创建方法重定向到索引？

The articles creation url is /articles/new but when the submit fails, I'm redirected to /articles. The form is still available in /articles exactly as it was on /articles/new. The desired behavior would be to return to the /articles/new with whatever the user may have entered repopulated in the form. Is there a way to do this?
