我怎么能担心我这样写过:
module Concerns
module MyConcern
extend ActiveSupport::Concern
...
def my_concern_magic(arg0,arg1)
#exciting stuff here
end
end
end
包含在重载my_concern_magic
的模型中?例如。
class User
include Concerns::MyConcern
...
def my_concern_magic(arg0)
arg1 = [1,2,3]
my_concern_magic(arg0,arg1)
end
end
答案 0 :(得分:11)
由于包含模块将其插入祖先链中,您只需拨打super
:
class User
include Concerns::MyConcern
def my_concern_magic(arg0)
arg1 = [1, 2, 3]
super(arg0, arg1)
end
end
