Since Ruby doesn't support to override logic oprators,
so please pay attention to use oprators below when you are using OpenHash:
-
&&,and -
||,or &.
The most recommend way once you have to do some logic checking:
person = OpenHash.new
# Wrong
city = person.city || "London"
# Right
city = person.city.nil? ? "London" : person.city
# Wrong
state = person.is_succeed && "Success"
# Right
state = "Success" if !person.is_succeed.nil?
# Wrong
person.city&.upcase
# Right
!person.city.nil? && person.city.upcaseLicense
