title: Rails 4 + BootStrap 4 button issue
body: <p>Hello I have a quick question I can't actually get a bootstrap 4 button to work in rails this is my button code </p>
  
  <pre><code>&lt;%= link_to 'LifeHacks', controller: 'hacks', class: 'btn btn-primary' %&gt;
  </code></pre>
  
  <p>I thought that would work but it ends up being apart of the url instead like this "<a href="http://localhost/hacks?class=btn+btn-primary" rel="nofollow">http://localhost/hacks?class=btn+btn-primary</a>"</p>
