from south.db import db replaced by what in django 1.7+?

Question

I'm amending someone else's code to run with django 1.8 and I wonder if there is a direct replacement for the line

 from south.db import db

uses include:

if db.backend_name == "postgres":
    db.start_transaction()
    db.execute_many(commands.PG_DISABLE_TRIGGERS)
    db.commit_transaction()

Answer 1

As far as I understand, the replacements are:

from django.db import connection
from django.db import transaction

Usages:

>>> from django.db import connection
>>> connection.vendor
u'postgresql'

And:

from django.db import connection
from django.db import transaction

cursor = connection.cursor() 
with transaction.atomic():
    cursor.executemany(commands.PG_DISABLE_TRIGGERS)
