title: adding a class to a text_field_tag
body: <p>I am trying to give a class to my text_field_tag</p>
  
  <p>I have this</p>
  
  <pre><code>&lt;%= text_field_tag :login_aei, class: 'form-control' %&gt;
  </code></pre>
  
  <p>but it keeps generating this :</p>
  
  <pre><code>&lt;input type="text" name="login_aei" id="login_aei" value="{:class=&gt;&amp;quot;form-control&amp;quot;}"&gt;
  </code></pre>
  
  <p>What am I doing wrong ?</p>
