Final answer:
In Rails, a route is a way to direct incoming web requests to appropriate controllers and actions. It involves configuring a routing table within the application using a DSL, defining paths and their corresponding handling code.
Step-by-step explanation:
A route in Rails is a way to redirect incoming web requests to controllers and actions. It defines how the Rails application responds to a user request to a particular URL, how parameters are parsed, and ultimately which controller gets to handle the request. The mapping between the URLs and the code that handles them is set in the routing table.
The quantification of routes does not strictly relate to Rails routes. Since Rails is a web application framework, routes in this context refer to the paths that a user can take through an app to reach a given controller or view.
Configuring routes in a Rails application involves using a DSL (Domain-Specific Language) within the config/routes.rb file. Here, developers can declare paths and specify which controllers and actions they should be routed to, using a syntax that is both expressive and concise.
