Calling private parent class method from parent class (django)

Question

I want to call a redefined private method from an abstract parent class. I am using django if that matters.

class Parent(models.Model):
    def method1(self):
         #do somthing
         self.__method2()

    def method2(self):
         pass # I also tried calling up a prent method with super

class child(Parent):
    def method1(self)
        super(Child, self).method1()

    def __method2(self):
        #do something

I get a

AttributeError: "'Chil' object has no attribute '_Parent__method2'"

What I am doing wrong ?

Answer 1

Initial double underscores prevent polymorphism since both the method definition and the method call get mangled, to two different names. Replace with a single underscore to fix this.

Also, double underscores are not used for "private" attributes, and you should discard whatever reference told you that they are. They're used for MI disambiguation.
