I suggest you to study a little about ruby before starting with rails. This
also is a "problem" about variable scope.
To use a variable in the view, it must be an instance variable, in your
case:
@photos = Photo.order(:title)
and in the view you have 2 errors: `|products|` should be `|photo|` and
inside the loop you must use the `photo` variable (which have a different
value every cycle of the loop).
<% @photos.each do |photo| %>
<%= photo.user_id %>
<% end %>
