How to add a classmethod in Python dynamically

Question

I\'m using Python 3. I know about the @classmethod decorator. Also, I know that classmethods can be called from instances.

class HappyClass(object):
    @classme         


        

Answer 1

How I achieved it:

@classmethod
def search_url(cls):
    if not hasattr(cls, '_search_url'):
        setattr(cls, '_search_url', reverse('%s-search' % cls._meta.model_name))
    return cls._search_url
