RailsOnRails is unique in its ability to create a complete, working web application in approximately 5 minutes. A solid RoR engineer should be able to demonstrate this.

Create a new RoR application with two models: Blog and Comment. Blog should have two string properties: title and body. Comment has one string property: body. A Comment belongs to a Blog.

Configure routes such that Blogs are shown from path /blogs/:id and the comments for a particular blog are created at /blogs/:blog_id/comments/new and viewed at /blogs/:blog_id/comments.
