单独使用django的orm带事务

import os
import datetime
from django.conf import settings
os.environ['DJANGO_SETTINGS_MODULE'] = "settings"  #必须在导入transaction之前设置settings模块的名称，transaction会引用settings模块
from django.db import transaction

if not settings.configured:
    settings.configure(
        #DATABASE_ENGINE = 'sqlite3',
        #DATABASE_NAME= os.path.join( os.path.dirname(__file__), 'db\\sqlite3.db'),
        DATABASES = {
            'default': {
                'ENGINE': 'sqlite3',
                'NAME': os.path.join( os.path.dirname(__file__), '\\sqlite3.db'),
            }
        }
    )
     

from django.db import models
class Person(models.Model):
    class Meta:
        db_table = 'persons'
        app_label = 'test'

    created_at = models.DateTimeField('created_at', auto_now_add = True)
    updated_at = models.DateTimeField('updated_at', auto_now = True)
    name = models.CharField("name", max_length = 20)
    age = models.IntegerField("age")
time1 = datetime.datetime.now()
with transaction.commit_on_success():
    for i in range(100000):
        p = Person()
        p.name = "a"
        p.age = 111
        p.save()
time2 = datetime.datetime.now()
print (time2-time1).seconds
