'Rails: rendering a partial for a nested resource

# routes.rb
resources :topics do
  resources :bookmarks, except: [:index]
end

The view files for my Bookmark model live in app/views/topics/bookmarks:

enter image description here

I render a bookmarks partial from within views/topics/_topic.html.erb:

...
<% if topic.bookmarks.count > 0 %>
  <% topic.bookmarks.each do |bookmark| %>
    <%= render partial: 'topics/bookmarks/bookmark', locals: { topic: topic, bookmark: bookmark } %>
  <% end %>
<% end %>
...

My problems is that I'm receiving a Template Missing error when trying to render the Bookmark partial. Is the path I'm passing to render partial: incorrect? I've also tried render partial: 'bookmarks/bookmark.

Missing template bookmarks/edit, application/edit with {:locale=>[:en], :formats=>[:html], :variants=>[], 
:handlers=>[:erb, :builder, :raw, :ruby, :coffee, :jbuilder]}.

Solution 1:[1]

I think that your controller should follow the same structure that you want to use in your views folder, so your bookmarks controller should be defined like this:

class Topics::BookmarksController < ApplicationController

And it should be placed in the /controllers/topics/ folder.

You can see something related to that in Rails guide

I'm not sure if this is the best practice, but I tried do this, change from this:

<% topic.bookmarks.each do |bookmark| %>
<%= render partial: 'topics/bookmarks/bookmark', locals: { topic: topic, bookmark: bookmark } %>
<% end %>

to this:

<%= render partial: 'topics/bookmarks/bookmark', :collection=> @topic.bookmarks.all %>
