[Answered ]-How to give permission to admin and author for view specific page in django?

Using your example:

def get_object(self):
    obj = super(BlogListMyAccount,self).get_object()
    if obj.author  != self.request.user and not self.request.user.is_superuser:
       raise PermissionDenied      
    return obj

Usually this is how you check if the user have admin permissions: request.user.is_superuser.
