python - Django - queryset caching request-independent? -

-

i need cache mid-sized queryset (about 500 rows). had on solutions, django-cache-machine being promising.

since queryset pretty static (it's table of cities that's been populated in advance , gets updated me , anyway, never), need serve same queryset @ every request filtering.

in search, 1 detail not clear me: cache sort of singleton object, available every request? mean, if 2 different users access same page, , queryset evaluated first user, second 1 cached queryset?

i not figure out, problem facing. saying classical use case caching. memcache , redis 2 popular options. needs write method or function first tries load result cache, if not there , queries database. e.g:- 

from django.core.cache import cache  def cache_user(userid):        key = "user_{0}".format(userid)        value = cache.get(key)        if value none:              # fetch value db              cache.set(value)         return value

although simplicity, have written function, ideally should manager method of concerned model.

c# - TransactionScope not rolling back although no complete() is called -

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
