Rails uses four naming conventions for throughout it's code which need to
be followed by the developer (you) for their code to fit with Rails. These
involve selective use or* singular* and *plural *together with *camelize*and
*underscore*.
The simplest way to demonstrate the conventional use is to run:
*rails generate scaffold your_new_object name:string
description:text size:integer*
Then look at the model/view/controller files for uses of the variants on *
your_new_object
your_new_object
your_new_objects
YourNewObject
YourNewObjects
*If you're running on a unix system (any Linux or OSX) this command will
find them all when run within your application directory:
*find . -name \*.rb -exec grep your_new {} \; -a -exec grep YourNew
{} \; -a -print*
