TransactionNowLink to this heading#

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

Mengembalikan tanggal dan waktu pada peladen basisdata yang transaksi saat ini dimulai. Jika anda tidak dalam transaksi itu akan mengembalikan tanggal dan waktu dari pernyataan saat ini. Ini adalah melengkapi pada django.db.models.functions.Now, yang mengembalikan tanggal dan waktu dari pernyataan saat ini.

\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.

\n

Usage example:

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