如何在Intitalize中訪問此變量？

Question

可能重複：
How Do I Access This Variable?

可以說我有代碼：

class Player 
    def getsaves 
    print "Saves: " 
    saves = gets 
    end 
    def initialize(saves, era, holds, strikeouts, whip) 
    end 
end 

我希望能夠訪問在initialize方法getsaves的保存變量說：

j = Player.new(getsaves_saves_variable, 30, 30, 30, 30) 

Answer 1

定義的屬性：

attr_accessor :saves_attr 
attr_accessor :era_attr 
attr_accessor :holds_attr 
attr_accessor :strikeouts_attr 
attr_accessor :whip_attr 

def initialize(saves, era, holds, strikeouts, whip) 
    self.saves = saves 
    self.era_attr = era 
    ... 
end 

然後getsaves你可以這樣做：

self.saves_attr = gets
