hi Django Team,

may be I get some problem by following to django docs, in programe the Models logic,
the docs notice that get method get() do not use a cache (see Caching and QuerySets). Rather, they query the database each time they're called. but when in fact I check the source /usr/local/lib/python2.7/dist-packages/django/db/models/ line 130

def get(self, *args, kwargs):

return self.get_query_set().get(*args, kwargs)

the method is use the cache of the querySet , and I need some help to know How do I use a query get() DO NOT Use a Cache, thanks many, btw sorry about my English.

No, get_query_set() is only creating a new QuerySet instance.
