There doesn’t seem to be any explanation of how the scaffolds and controllers for the depot application relate back to the Flow of buyer/seller pages (figures 6 & 7) or even the Inital guess at application (figure 8). To me, this is the hardest part of mastering RoR.
Chapter 8 dives into the second controller, Store, without every relating it back to the interviews with the client, or the use case and flow diagrams created from them. I would really like to see a discussion of how the scaffolds and controllers were factored out of the information provided by the client.
Does anyone know where I can find more information and examples of how to determine the scaffolds and controllers from the basic analysis of the system to be created?
