[Fixed]-Django multi table inheritance: Find and change parent model

✅

If you have a normal parent-child models you will get attribute in child to access parent. You can update this attribute with new parent object.

Also, the way you create parent object may not work, you need to call method on that object.

So I will update child’s copy() method as:

class B(A):

    def copy(self):
        # this method is what I am confused about
        new_parent = self.a.copy()  # change 'a' with appropriate attribute name
        obj = self
        obj.pk = None
        # set obj's parent model to 'new_parent'
        obj.a = new_parent
        obj.save()
        return obj
