Call overwritten method of included module?

Ruby
1

Hi all

module MyModule
def my_method
return “my module rocks!”
end
end

class MyClass
include(MyModule)

def my_method
return “my class rocks!”
end
end

Is there a way to call MyModule::my_method from within MyClass? “super”
sadly doesn’t work…

Thanks a lot
Josh

Perhaps this will do:

module MyModule def my_method "my module rocks!" end end

class MyClass
include MyModule
alias module_method my_method
def my_method
“#{module_method}\nmy class rocks!”
end
end

puts MyClass.new.my_method

 my module rocks! my class rocks!

You’d need to alias the old method:

class MyClass
include(MyModule)
alias :old_my_method :my_method
def my_method
old_my_method
end
end

(If you’re using rails/activesupport, you’d probably use
alias_method_chain to simplify things)

Thanks! Especially for the alias_method_chain hint! :slight_smile:

super shall work and indeed does
module MyModule
def my_method
return “my module rocks!”
end
end

class MyClass
include(MyModule)

def my_method

 return [ super, "my class rocks!" ].join("\n")

end
end

puts MyClass.new.my_method
