Forum: Ruby on Rails One of my routes is not working

I have a User model which has_many :portfolios and each Portfolio 
has_many
:pictures. My routes look like this:

resources :users do
  resources :portfolios do
    resources :pictures
  endend

Then I try to create a new Portfolio like this:

<%= link_to "new portfolio...", new_user_portfolio_path(current_user) %>

With a form like this:

<%= form_for [current_user, @portfolio], html: { class: "form_settings" 
} do |f| %>...<% end %>

But when I click on "new portfolio..." my URL says 
/users/12/portfolios/new and I get this error:


No route matches {:action=>"show", :controller=>"portfolios", 
:user_id=><User id: 12, name: "michael", password_digest: 
"d787f56b080945c1ec0b3343cbf962ca427bb8ef", remember_token:
