Monkey patching (Coding Horror):
class ActiveRecord
private
def hi
'I am private'
end
end
class MyActiveRecord < ActiveRecord
def greet
hi
end
private
def hi
'I am redefining you'
end
end
a = MyActiveRecord.new
p a.greet
Unnecessary Complication:
class Client
def print
say
end
private
def say
"hello"
end
end
# Create a subclass of Client
MyClient = Class.new(Client) do
define_method(:say) do
"hello from an overridden private method"
end
end
puts MyClient.superclass
my_client = MyClient.new
puts my_client.print
Simpler Way to Accomplish the Same Thing:
class Client
def print
say
end
private
def say
"hello"
end
end
class MyClient < Client
def say
"hello from an overridden private method"
end
end
puts MyClient.superclass
my_client = MyClient.new
puts my_client.print
