html_safe with undefined fields

Question

i have a field which is not required i.e. can be nil. i want to use the ffg: myfield.html_safe in my view. this doesn't work for the items that have no myfield. i get an exception, how do i get html_safe to apply only if the field is defined? thanks

In Rails, you can use

myfield.try(:html_safe)
