Shortcut for ternary operation in views

Rails
1

Hi,

I attended a recent Rails Edge conference and seem to recall a new
built-in
shortcut to the following, frequently used, code:
<%= foo.nil? ? ‘’ : foo %>

Does anyone know what that might be?

Thanks,
Mark

Well, it’s nothing new:

<%= “#{foo}” %>

Since nil.to_s is an empty string and string interpolation does a .to_s

<%= foo.to_s %>

also works.

<%= %> does a to_s too, so:

<%= foo %>

should be OK.
