title: The Equivalent to LINQ's `FirstOrDefault` (predicate) in Rails's Active Record
body: <p>In Entity Framework, you can use a predicate method to get the first column in query based on a conditional, i.e. <code>FirstOrDefault((row) =&gt; row.Something == &quot;bla&quot; &amp;&amp; row.Good == true)</code></p>
  <p>How do you do that in Ruby on Rails?
  Without the usage of the <code>where</code> method?</p>
