Cache miss each time if used on class instance method

[darklow]

Looks like self param is being taken into account.
Current workaround that works is using empty args_rewrite list:

class MyClass(object):

    @cache_memoize(30, args_rewrite=lambda x: [])
    def get_data(self):
      #....

That's not issue but expected behavior.
I see at least two correct ways to handle this situation:

@cache_memoize(30, args_rewrite=lambda self, *args: args)
def get_data(self):
    pass

or

from django.utils.decorators import method_decorator


@method_decorator(cache_memoize(30, prefix='get_data'))
def get_data(self):
    pass

+1 on method_decorator

The only downside with this is that you then can't use the hot cache pattern. e.g.

MyClass.get_data(MyClass, refresh=True)

gives get_data() takes 1 positional argument but 2 were given

Is there a workaround you can think of here?

Ahh actually, in my case this works if I add in an args_rewrite=lambda: 'manager_fn', which is fine because I want to cache the result globally across a model

I suggest documenting the method_decorator trick. Can I open a PR with that?
