Question

I have put a Jira client for my django application together and now need to make it static but I can’t figure how to convert @property and @?.setter into static fields:

Say I have a class:

class nothing(object):
    auth_token = None
    counter = 0

    @property
    def a(self):
        self.log('getter')
        if not self.auth_token:
            self.auth_token = 'default'
        return self.auth_token

    @a.setter
    def a(self, value):
        self.log('setter')
        self.auth_token = value

    def log(self, value):
        self.counter+=1
        print '{0} called / counter: {1}'.format(value, self.counter)

and I want its methods to be static:

class nothing:
    auth_token = None
    counter = 0

    @staticmethod
    def get_a():
        nothing.log('getter')
        if not nothing.auth_token:
            nothing.log('auth_token value is None, setting')
            nothing.auth_token = 'default'
        return nothing.auth_token

    @staticmethod
    def set_a(value):
        nothing.log('setter')
        nothing.auth_token = value

    @staticmethod
    def log(value):
        nothing.counter+=1
        print '{0} called / counter: {1}'.format(value, nothing.counter)

can’t mark get_a as @property now as calling it will return an object and not actually call get_a. Methods are something I can live with but is there a way to have getters/setters instead?

Answer 1

The easiest way is to make this class singleton. Instead of making methods static, override class with its instance:

nothing = nothing()

You can also use metaclasses if you want to have more than one instance.
