Search in rails routes

You will have four outputs for each route. These outputs are the route name (if it exists), the HTTP verb, the url pattern and the routing parameters (if they are used). These four pieces of information are very useful in determining the full route including namespaces, what the components of the URI are, the action that will be performed when the endpoint is hit and what kind of parameters can be expected.
