Included resources in development

I'm new to rails and I would like some advice on my routes and correct routing logic. I am working on a very simple application where users can post lists. The user (modeler) has multiple lists, and the list is owned by the user. My list table has user_id: integer. When the user successfully logs in, I would like them to see their lists on the corresponding route page I created nested routes like this:

devise_for :users, :paths => 'users'

resource :users do
  resource :lists
end

This is the result of my rake routes

new_user_session GET    /users/sign_in(.:format)       devise/sessions#new
            user_session POST   /users/sign_in(.:format)       devise/sessions#create
    destroy_user_session DELETE /users/sign_out(.:format)      devise/sessions#destroy
           user_password POST   /users/password(.:format)      devise/passwords#create
       new_user_password GET    /users/password/new(.:format)  devise/passwords#new
      edit_user_password 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 GET    /users/cancel(.:format)        devise/registrations#cancel
       user_registration POST   /users(.:format)               devise/registrations#create
   new_user_registration GET    /users/sign_up(.:format)       devise/registrations#new
  edit_user_registration 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
             users_lists POST   /users/lists(.:format)         lists#create
         new_users_lists GET    /users/lists/new(.:format)     lists#new
        edit_users_lists GET    /users/lists/edit(.:format)    lists#edit
                         GET    /users/lists(.:format)         lists#show
                         PATCH  /users/lists(.:format)         lists#update
                         PUT    /users/lists(.:format)         lists#update
                         DELETE /users/lists(.:format)         lists#destroy
                   users POST   /users(.:format)               users#create
               new_users GET    /users/new(.:format)           users#new
              edit_users GET    /users/edit(.:format)          users#edit
                         GET    /users(.:format)               users#show
                         PATCH  /users(.:format)               users#update
                         PUT    /users(.:format)               users#update
                         DELETE /users(.:format)               users#destroy
                    root GET    /                              static_pages#home

How can I achieve my routes:

/users/:user_id/lists(.:format)

This would also be a step to make sure the user only has access to their lists.

You should use the resources

method instead resource

:

resources :users do
  resources :lists
end

Take a look at this Rails Guides . It contains a good example with explanations.

And for this:

This would also be a step to make sure the user only has access to their lists.

You can use one of the design methods of support : current_user

:

current_user.lists

UPD: But I think it's easier to create lists than a separate (not nested) resource. Something like that:

# config/routes.rb
Rails.application.routes.draw do
  # ...
  resources :lists
end

# app/controllers/lists_controller.rb
class ListsController < ApplicationController
  before_action :authenticate_user!

  def index
    @lists = current_user.lists
  end
end

So, along the way, /lists

some user will only have access to their own lists. What is it.

I think you can do this:

resources :users do resources :lists end

Pluralization is the key.

There is a link to this part of the docs here

I would use an authorization like cancancan or pundit to control which lists the user can or cannot see. Hope it helps!

You probably want to split the list resources and make the user resource unique:

resource :user do
  resources :lists
end

For the second part, just load the lists based on the current user wherever you need them.

@lists = current_user.lists
