Question

This must be very simple. But I just can’t seem to find the proper solution.

I have a model with an embedded video attribute.

I made it happen like this:

 On my show page
 <iframe width="560" height="315" src="<%= @trip.youtube %>" frameborder="0" allowfullscreen></iframe>

Everything works fine, but the thing is that i don’t want to show this part if the youtube url is blank. Otherwise I am left with a huge white space, which I don’t need.

I’ve tried to play around with unless or if conditions

 <% if @trip.youtube.blank? %>
  <iframe width="0" height="0" src="<%= @trip.youtube %>" frameborder="0" class="hidden" allowfullscreen></iframe>
 <% else %>
   <iframe width="560" height="315" src="<%= @trip.youtube %>" frameborder="0" allowfullscreen></iframe>
 <% end %>

But I’m doing something wrong.
Any suggestions for a better way ?
Thanks.

Answer 1

Why not just use:

<% if @trip.youtube.present? %>
    <iframe width="560" height="315" src="<%= @trip.youtube %>" frameborder="0" allowfullscreen></iframe>
<% end %>

And leave it at that?
