title: How do I get ActiveRecord to show the next id (last + 1) in Ruby on Rails?
body: <p>Is there a compact way with ActiveRecord to query for what id it's going to use next if an object was going to be persisted to the database? In SQL, a query like this would look something like:</p>
  
  <pre><code>SELECT max(id) + 1 FROM some_table;
  </code></pre>
