Route not being detected for nested resource in Rails 4

Question

# routes.rb
resources :assets, only: [:new, :create, :delete]

# asset.rb
class Asset < ActiveRecord::Base
  belongs_to :post
end

# rake routes
         Prefix Verb   URI Pattern                            Controller#Action
post_comments POST   /posts/:post_id/comments(.:format)     comments#create
new_post_comment GET    /posts/:post_id/comments/new(.:format) comments#new
       posts GET    /posts(.:format)                       posts#index
             POST   /posts(.:format)                       posts#create
    new_post GET    /posts/new(.:format)                   posts#new
   edit_post GET    /posts/:id/edit(.:format)              posts#edit
        post GET    /posts/:id(.:format)                   posts#show
             PATCH  /posts/:id(.:format)                   posts#update
             PUT    /posts/:id(.:format)                   posts#update
             DELETE /posts/:id(.:format)                   posts#destroy
   post_form POST   /post_form(.:format)                   posts#form
        root GET    /                                      posts#index

No routes show up for assets, though I need to be able to delete them without specifying a post_id, because they can exist without a post at the moment (necessary in order to be able to upload files and recerence these files in the new post).

The routes assets#new and assets#create work just fine, but not assets#destroy (I get an error saying DELETE /assets/<id>is undefined.

Help please! :-)

For destroy to work,

Change the line in your route.rb(notice :destroy instead of :delete)

resources :assets, only: [:new, :create, :destroy]
