title: Is save method mandatory in rails?
body: <pre><code>Model.find(ids).each { |model| model.is_active = false } unless ids.empty?
  </code></pre>
  
  <p>Here, is model.save method necessary or not ? Because without that also, it's working.</p>
  
  <p>Column is defined like this </p>
  
  <pre><code>t.integer :is_active, limit: 1
  </code></pre>
