I have a Rails view which I would like to receive a list of ids from the controller and make a photo box for each ID. My current code receives the list and creates a box for each one perfectly fine, but any time I try to output or display the variable it acts like the variable is empty.

Controller

def index
  @photos = Photo.all
  @photo_ids = Feed.find(4).approved_contents
  @ids = @photos.ids.as_json
  Rails.logger.info(Feed.find(4).approved_contents.ids.as_json)
end

Template

<p id="notice"><%= notice %></p>
<h1>Listing Photos</h1>
<br>
<div class="row">
  <% @photos.each do |photo| %> 
  <div class="col-sm">
    <div class="card" style="width: 18rem;">
      <img class="card-img-top" src="/content/46/display" alt="Card image cap">
      <div class="card-body">
        <p class="card-text">
          <% photo.inspect %>
        </p>
      </div>
    </div>
  </div>
  <% end %>
</div>
<% @photos.length %>
<%= link_to 'New Photo', new_photo_path %>

Output HTML

<!DOCTYPE html>

You need to replace

      <% photo.inspect %>

with 

      <%= photo.inspect %>

see this answer.
