Can anyone explain the difference between accessing an instance attribute via self.attribute and by @attribute?
self.attributecalls the methodattribute.self.attribute = valuecalls the methodattribute=with the argumentvalue.@attributeand@attribute = valueget/set the value of the instance variable@attribute.So basically they’re two entirely different things.
However if you call
attr_accessor :attributeit defines the methodattributeto return@attributeand the methodattribute=(value)to set@attribute = value. So in that case, there is no difference.
