How do I add a new route (URL)? Question

You can add a new route in the file config/routes.rb, and the existing routes in that file for the other "tabs" on the user profile page show the template to follow.

The relevant part of the routes file starts on line 180:

scope  'users' do

Everything inside this scope block effectively has users prepended to its URL. For example, line 186 has:

    get  '/me',  to: 'users#me',  as: :users_me

This lists the URL as /me but is actually triggered by the URL users/me due to being inside the users scope block.

Similarly line 200 has:

    get  '/:id',  to: 'users#show',  as: :user

This is triggered by the URL users/:id (such as users/1234).

The other tabs on the user profile page have URLs of the form users/:id/something and can be found in this block listed as just /:id/something (or /me/somethng for the ones not visible to the public other than the user).

What the components mean

GET

The get at the beginning of the line means that this is triggered by a GET request (often used for visiting the page rather than making a background server request).

URL

The URL reflects what link the user followed, subject to having the scope (in this case users) prepended.

To

The to: 'users#show' is interpreted in both of two ways:

1. This URL results in a call to the show method of the UsersController.
2. The view rendered is the file show.html.erb in the directory users.

As

The as: :user is an optional renaming of the helper functions that Rails automatically creates for each route.

By default, the methods users_show_path and users_show_url would be created (matching users#show). The as overrides this to have the methods be called user_path and user_url instead.
