It's not clear if "Rails Applications Without Scaffold" is a new project or not #1
Description
It's not really quite clear whether the section "Rails Applications Without Scaffold" (page 31) is intended to continue working on the existing project or to start a new project.
e.g. The content at the start of the section indicates that the character Aling wants a whole new project, and the statement "This is a good time to discuss how to create a program from scratch" indicates that you will need to create a new project.
However, the first command executed is to generate a model for a class which if you try to do outside the scope of the previous application it won't work.
Suggest adding some clarity that this new project requires a command to "rails new alingnina-inventory" or whatever before getting into the model.
Suggest rewording so that it doesnt give the impression that you need to create a new app....i only discovered I didnt need the new app about 2 pages later.
(this tripped me up for a few mins as a rails n00b and reading this document in tiny parts over the course of many weeks).
