Method invocation from parent class

[Dmitriy Non]

You can achieve it via

def method2
ClassA.instance_method(:method1).bind(self).call
end

But there obviously something wrong with your design so I suggest you
fix it instead of using something like code above.

If you don't want your method to be overridden then just don't.
Do something like:


class A
def method1
some_private_method
end

def method2
puts 'A#method2'
some_private_method
end

private

def some_private_method
puts 'whatever'
end
end

class B < A
def method1
puts 'B#method1'
end
end

B.new.method2

Hi All,
class ClassA
def method1()
puts("From method1 of ClassA")
end
def method2()
puts("From method2 of ClassA")
method1() // <---- Here is the problem, I would like to call method1 from the same ClassA, although it is applied to instance of ClassB!
end
end
class ClassB < ClassA
def method1()
puts("From method1 of ClassB")
end
def method2()
super()
puts("From method2 of ClassB")
end
end
b = ClassB.new()
b.method2()
From method2 of ClassA
From method1 of ClassB
From method2 of ClassB
From method2 of ClassA
From method1 of ClassA
From method2 of ClassB
How can I implement this?
Thank you!

BTW, instead of `ClassA.instance_method(:method1)` you can do: `method(:method1).super_method.call`

I agree. This is suspicious. For this discussion it would be helpful
if methods are a bit more concrete than "method1" and "method2". We
might be able to come up with much better advice if we knew the real
scenario.

Kind regards
