Is there an equivalent null prevention on chained attributes of groovy in ruby?

Question

Groovy:

if there`s my_object -> access \'name\' and capitalize

my_object?.name?.capitalize()

What is the equivalent for ruby to avo

Answer 1

Assuming you mean you want to avoid a nil error if my_object is nil. Try :

my_object?.name?.capitalize() unless my_object.nil?

Ruby will do the nil check first and only then try to access the attribute if my_object isn't a null.
