You have asked for action rent on the movies controller but you have
not provided a route for that.

I suggest you work right through a good tutorial such as
railstutorial.org (which is free to use online) which will show you
the basics of rails.

If you have a look at the Rails Guide on Routing then it will show you
how to do it, but best to work through the tutorial first.
