title: Understand the require of strong parameters - Rails
body: <p>I have a <code>filters controller</code> and a integration object that has <code>tags</code>. I'm trying to update the integration object. I'm using strong params that look like this. </p>
  
  <pre><code>def filters_params
    params.require(:filters).permit(:tags)
  end
  </code></pre>
  
  <p>What exactly is the <code>require</code> in strong params? is it the key? And how could I make this work?</p>
