Implicit argument passing of super from method defined by define_method() is not supported

Question

In \"Agile Web Development with Rails\" (third edition) page 537 - 541 it has \"Custom Form Builders\" code as follows:

  class TaggedBuilder < Actio         


        

Answer 1

I encountered with this problem in a define_method without arguments

define_method :"#{info_type}_info" do

  info = super
  .......

end

And still found this problem. I had to explicit put the parenthesis:

define_method :"#{info_type}_info" do

  info = super()
  .......

end

Answer 2

The super above passed all parameters (see this recent question).

As the error message states, you must here "specify all arguments explicitly". Replace super with super(label, *args).
