What's the Difference Between These Two Ruby Class Initialaztion Definitions?
- by michaelmichael
I'm working through a book on Ruby, and the author used a slightly different form for writing a class initialization definition than he has in previous sections of the book. It looks like this:
class Ticket
attr_accessor :venue, :date
def initialize(venue, date)
self.venue = venue
self.date = date
end
end
In previous sections of the book, it would've been defined like this:
class Ticket
attr_accessor :venue, :date
def initialize(venue, date)
@venue = venue
@date = date
end
end
Is there any functional difference between using the setter method, as in the first example vs. using the instance variable in the second? They both seem to work. Even mixing them up seems to work:
class Ticket
attr_accessor :venue, :date
def initialize(venue, date)
@venue = venue
self.date = date
end
end
