title: simple_form - how to specify form's action attribute
body: <p>I am using simple_form gem and have a ordinary rails scaffold which is working perfectly - I am able to update/create/destroy records.</p>
  
  <p>When I add the views in application  <em>&lt;%= yield %></em> a issue occurred - the simple_form gem is rendering a form with action "/" for the new action and I was not able to create new records.</p>
  
  <p>In my controller, the path for create action is </p>
  
  <pre><code> #POST /webinars
  </code></pre>
  
  <p>So, I edit the action of the form from "/" to "/webinars" (using the browser console) and then successfully create a record.</p>
  
  <p>I suppose that I should override the action of the from somehow, but was not able to find how.
  Is this the real problem?</p>
