Rails 4 - Displaying a dependent model in a table - ruby-on-rails

Question

I have an Article model, with a dependent model Photocup. Each Photocup instance has an image attached (using paperclip/imagemagick). I followed the rails guide for adding a second model, the same way Comments are associated with an Article.
http://guides.rubyonrails.org/getting_started.html#adding-a-second-model
It works fine. But I want more control over how the Photocups are displayed. I've created a partial _gallery.html.erb in Views/Article. The gallery partial looks like this:
Photo Gallery
<table class="table2">
<%= render #article.photocups %>
</table>
_photocup.html.erb in Views/Photocup looks like this"
<td>
<%= photocup.label %>
<br>
<%= image_tag photocup.image(:small) %>
<br>
<%= link_to 'Remove Photo', [photocup.article, photocup],
method: :delete,
data: { confirm: 'Are you sure?' } %>
</td>
Works fine, but I can't figure out how to add in a row!
Is there anyway to display the Photocups for the Article I'm looking at the way one does with non-dependent model? For example, an index page would typically have something like this"
<table>
<tr>
<th>Title</th>
</tr>
<%= #photocups.each do |photocup| %>
</tr>
<td><%= photocup.title %></td>
<% end %>
</table>
Could this be done on the show.html.erb page for the article somehow? Could it be done if I created a partial in Views/Photocup?
If it matters, the route looks like this:
resources :articles do
resources :comments
resources :photocups
get 'gallery'
get 'showall'
get 'feature', on: :collection
end
Thank you in advance for any help.

Answer 1

It can be on the articles#show page. Provided your associations are done correctly, you have a:
#article.rb
Class Article > ActiveRecord::Base
has_many :photocups
end
and
#photocup.rb
Class Photocup > ActiveRecord::Base
belongs_to :article
end
You'll have to declare an instance variable under the show action in the Articles controller. It'll look something like this:
#articles_controller.rb
def show
#article=Article.find(params[:id])
#photocups=#article.photocups
end
Then use the code for your example index view in your show view and it should show the rows you are seeking.
Also, side note, this line:
<%= #photocups.each do |photocup| %>
in your example index page does not need an =. Those should be reserved for things you want the user to see in the view, it should be:
<% #photocups.each do |photocup| %>.
