Oh CRUD!
In chapter 3, you began writing stories for a CRUD (create, read, update, delete)
interface for your Project resource. Here, you continue in that vein, beginning
with writing a story for the R part of CRUD: reading. We often refer to reading as
viewing in this and future chapters—we mean the same thing, but sometimes viewing
is just a better word.
For the remainder of the chapter, you’ll round out the CRUD interface for projects,
providing your users with ways to edit, update, and delete projects too. Best of
all, you’ll be doing this using behavior-driven development the whole way through.
4.1 Viewing projects
The show action generated for the story in chapter 3 was only half of this part of
CRUD. The other part is the index action, which is responsible for showing a list of
the projects. From this list, you can navigate to the show action for a particular project.
The next story is about adding functionality to allow you to do that.
