Ruby on Rails - how it flows, and where the files go

Rails provides the framework for you to work in - you extend default (supplied) classes in your controller and model, and provide HTML files with embedded Ruby calls to supplied functions to add in your dynamic changes to the look and feel.
With rails providing a number of elements, you need to know where the hooks are to put your code / web page, and here are two diagrams from yesterday's course showing the elements in logical (operational) order, and where each of them fits in the file system tree.
The file names used aren't explicity stated as you write your code - they're implicitly derived from the the URL you use. Further, the method called demo within the floor controller is implicitly the code that was called when the URL was called up ...
The URL was http://localhost:3000/floor/demo (using WEBrick test server, running on the development machine, so - sorry - not available for you to click on and run on our live server!)
Next public Ruby course - the week after next - you'll find details [here]. If you come back to this page on the archives and have missed the June course, there are others later this year, and the schedule for next year will be published in the same place in the late summer.
