\nclass TransactionNowLink to this definition#
\n
\n\n

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.

\n

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

Sampla úsáide:

\n
Python console
>>> from django.contrib.postgres.functions import TransactionNow\n>>> Article.objects.filter(published__lte=TransactionNow())\n<QuerySet [<Article: How to Django>]>\n
