我得到「未初始化的常量日期(NameError)」用下面的代碼:紅寶石NameError時日期
class Test
attr_accessor :reqs
def initialize()
@reqs = []
end
end
class TestBuilder
def test(&block)
@current = Test.new
block.call
@current
end
def older_than_days(age)
@current.reqs << lambda { |email| ::Date.parse(email[:date]) < ::Date.today - age }
end
end
b = TestBuilder.new
x = b.test { b.older_than_days(1) }
p x.reqs[0].call({:date => "Mon, 5 Apr 2010 03:17:46 -0400"})
加入雙冒號閱讀回答這個問題後: Uninitialized constant ... NameError因爲ruby試圖在TestBuilder中找到Date。 Date是否在全局命名空間中?或者我在這裏做錯了什麼?
