attr_accessor :"#{name}"
end
end
end
end
=> nil
class MyNewClass
my_attr_accessor :id, :diagram, :telegram
end
=> [:id, :diagram, :telegram]
class MyClass
attr_accessor :id, :diagram, :telegram
end
=> nil
class Another_class
def initialize
["id","diagram","telegram"].each do |name|
self.class.class_eval do
attr_accessor :"#{name}"
end
end
end
end
=> nil
mnc = MyNewClass.new
=> #<MyNewClass:0xb7b97d0c>
mc = MyClass.new
=> #<MyClass:0xb7b950fc>
ac = Another_class.new
=> #<Another_class:0xb7b82358>
ac.diagram
=> nil
mc.diagram
