Question

I am storing in DB table data. In a column could be the value NULL and a string. And I can’t to find a condition, when is a string -> print this string, when is NULL, do something else…

I am trying something like this:

if @optional.logo.size > 3  && !@optional.logo.nil?
  ...In table is a STRING...
else
  ...In table is NULL...
end

but this is wrong… Can anyone help me, please, how to fix it?
Thanks you

You’ll have to test for nil first because a nil object will not have the size property.
