Depending on how much you've simplified it, you might see if the
following code helps. (I wonder if you really need to dynamically define
a new method; you certainly don't to achieve the desired output of your
sample.)
class B
puts "B class init"
def self.dynamic_method_outputs
@dynamic_method_outputs ||= []
end
def initialize
puts "B instance init"
end
def self.add_to_dynamic_method_output( val )
dynamic_method_outputs << val
end
def dynamic_method
self.class.dynamic_method_outputs.each do |v|
puts v
end
end
end
class D1 < B
add_to_dynamic_method_output 123
add_to_dynamic_method_output 456
end
class D2 < B
add_to_dynamic_method_output 789
end
d1 = D1.new
d1.dynamic_method
d2 = D2.new
d2.dynamic_method
#=> B class init
#=> B instance init
#=> 123
#=> 456
#=> B instance init
#=> 789
