class TransactionNowLink to this definition#

Tugann sé an dáta agus an t-am ar an bhfreastalaí bunachar sonraí a thosaigh an t-idirbheart reatha. Mura bhfuil tú i idirbheart, cuirfidh sé dáta agus am an ráiteas reatha ar ais. Is comhlánú é seo la:class: Django.db.Models.Functions.Now, a thugann dáta agus am an ráiteas reatha ar ais.

Note that only the outermost call to atomic() sets up a transaction and thus sets the time that TransactionNow() will return; nested calls create savepoints which do not affect the transaction time.

Sampla úsáide:

>>> from django.contrib.postgres.functions import TransactionNow
>>> Article.objects.filter(published__lte=TransactionNow())
