Routing examines the URL of an incoming request and determines what the application should do. “Rails routing can be a bit of a tough nut to crack. But it turns out that most of the toughness resides in a small number of concepts. After you’ve got a handle on those, the rest falls into place nicely,” says Rails developer Obie Fernandez.
In a chapter from his book The Rails Way, Fernandez explains how to best use the Rails routes.rb file, including what the default route does; as well as how to write custom
routes, use static strings and wildcards in routes, create your own “receptors,” and more.
