Cache helper to delete keys

[emilian]

Would it be cleaner to add a helper method in lfs.cache.utils to delete a key from the cache? Right now there is a lot of boilerplate in the code:

cache_key = "%s-%s-%s" % (settings.CACHE_MIDDLEWARE_KEY_PREFIX, Order.__name__.lower(), order.pk)
    cache.delete(cache_key)

We could change it to:

lfs_delete_cache_key(order)

Feedback?

Such clause is used once in the code (or I miss something). Is there really a reason to have it as a helper function?

I agree to pigletto. I don't think we need that. Thanks anyway!

I agree with pigletto as well. I thought the clause was being used a lot more times than it actually was.
