Username in urls - Ruby on Rails

Question

I am working on a project which includes signup, login and users can post articles. However I want to include username of the user in article url. So I did like this in routes.rb

scope '/:username' do
resources :articles, :path => '/status',  only: [:create, :destroy, :show]
end

Now when I open project index which shows all articles, I am getting this error.

No route matches {:action=>"create", :controller=>"articles"} missing required keys: [:username]

Am I doing something wrong?

Edit: Here is the output of rake routes

               GET    /:id(.:format)                  users#show
               PATCH  /:id(.:format)                  users#update
               PUT    /:id(.:format)                  users#update
               DELETE /:id(.:format)                  users#destroy
      archings POST   /:username/status(.:format)     articles#create
       arching GET    /:username/status/:id(.:format) articles#show
               DELETE /:username/status/:id(.:format) articles#destroy

Here is the code of routes.rb

Rails.application.routes.draw do
  root 'static_pages#home'
  get 'help' => 'static_pages#help'
  get 'signup' => 'users#new'
  get    'login'   => 'sessions#new'
  post   'login'   => 'sessions#create'
  delete 'logout'  => 'sessions#destroy'
  resources :users, shallow: true do
    resources :articles
   end
end

Although having really short URLs may be attractive you should not use a wildcard at the "lowest level" of your url schema - unless your application only really deals with a single type of resource. Adding a wildcard at the bottom level in your urls causes huge headaches since it will swallow every other route unless great care is taken.

I would really recommend that you use /users/:username/articles .

resources :users, shallow: true do
  resources :articles
end

This is a better restful design and it means that you do not have to blacklist usernames against a list of the other urls (and future urls) needed in your application.
