Here are the seven default routes for all controllers in Rails. Having said that pretty much every other RESTful framework adheres to these as well.

URL Action Named Route Purpose
GET /users index users_path page to list all users
GET /users/1 show user_path(1) page to show user with id 1
GET /users/new new new_user_path page to make a new user (signup)
POST /users create users_path create a new user
GET /users/1/edit edit edit_user_path(1) page to edit user with id 1
PUT /users/1 update user_path(1) update user with id 1
DELETE /users/1 destroy user_path(1) delete user with id 1
