<p>In <a href="https://github.com/openstreetmap/openstreetmap-website/pull/1309">app/models/user.rb</a>:</p>
<pre style='color:#555'>> @@ -4,6 +4,7 @@ class User < ActiveRecord::Base
   has_many :traces, -> { where(:visible => true) }
   has_many :diary_entries, -> { order(:created_at => :desc) }
   has_many :diary_comments, -> { order(:created_at => :desc) }
+  has_and_belongs_to_many :diary_entries_subscriptions, :class_name => "DiaryEntry", :join_table => "diary_entries_subscribers", :foreign_key => "subscriber_id"
</pre>
<p>Canonical rails would be <code>user_id</code> and <code>diary_entry_id</code> for the columns in a relationship table like this I think?</p>
