Devise with Rails 4: user show route doesn't exist - ruby-on-rails

Question

I am using the devise gem to handle all the sign up and sign in stuff. But I also want to add user profiles to my application, so I generated a user controller with only a show action. Then I added get 'users/:id' => 'users#show' to routes.rb. In fact, typing /users/1 works, but I can't find a way to name the route. What I want is to get something like show_user_path or user_path so I can link to a given user's content and show that user's profile.
Here is my routes.rb
Pinteresting::Application.routes.draw do
resources :pins
get 'users/:id' => 'users#show'
devise_for :users
root "pins#index"
get "about" => "pages#about"
And here are the routes I get with it (I highlighted the one I expect to be something like show_user_path):
pins_path GET /pins(.:format) pins#index
POST /pins(.:format) pins#create
new_pin_path GET /pins/new(.:format) pins#new
edit_pin_path GET /pins/:id/edit(.:format) pins#edit
pin_path GET /pins/:id(.:format) pins#show
PATCH /pins/:id(.:format) pins#update
PUT /pins/:id(.:format) pins#update
DELETE /pins/:id(.:format) pins#destroy
#this is the one I want a path! GET /users/:id(.:format) users#show
new_user_session_path GET /users/sign_in(.:format) devise/sessions#new
user_session_path POST /users/sign_in(.:format) devise/sessions#create
destroy_user_session_path DELETE /users/sign_out(.:format) devise/sessions#destroy
user_password_path POST /users/password(.:format) devise/passwords#create
new_user_password_path GET /users/password/new(.:format) devise/passwords#new
edit_user_password_path GET /users/password/edit(.:format) devise/passwords#edit
PATCH /users/password(.:format) devise/passwords#update
PUT /users/password(.:format) devise/passwords#update
cancel_user_registration_path GET /users/cancel(.:format) devise/registrations#cancel
user_registration_path POST /users(.:format) devise/registrations#create
new_user_registration_path GET /users/sign_up(.:format) devise/registrations#new
edit_user_registration_path GET /users/edit(.:format) devise/registrations#edit
PATCH /users(.:format) devise/registrations#update
PUT /users(.:format) devise/registrations#update
DELETE /users(.:format) devise/registrations#destroy
root_path GET / pins#index
about_path GET /about(.:format) pages#about

Answer 1

For devise, User is not the resource, it's just a scope. What devise cares about is authentication.
Although the paths are nested under /user, you will notice that the resources that are defined are actually things like sessions, registrations, passwords...
Just add resources :users in your routes and create a UsersController (and the views).
If you don't want to create all the resources for users and just be able to user user_path(user) with your get 'users/:id, you can name that route using the as option, like this:
get 'users/:id' => 'users#show', as: user

Answer 2

The answer above is great but I think it's worth noting here that if you don't want to create a different controller, but want to add an action to, say, your registrations controller that you inherit from the Devise::RegistrationsController, then you need to use the devise scope block:
devise_scope :user do
get 'users/:id' => 'registrations#show', as: user
end

Answer 3

the answer supposed to be like this:
get 'user/:id' => 'users#show', as: :user
