我尝试使用Django的bulk_create创建一些对象，但是我得到了TransactionManagementError。
Django在django-2.2.24上Mysql是通过docker运行的，我使用的是mariadb:10.10.2。

也许你应该用transaction.atomic来 Package 你的函数，这里是来自django文档的例子：
从django.db导入事务

@transaction.atomic
def viewfunc(request):
    # This code executes inside a transaction.
    do_stuff()

以及作为上下文管理器：

from django.db import transaction

def viewfunc(request):
    # This code executes in autocommit mode (Django's default).
    do_stuff()

    with transaction.atomic():
        # This code executes inside a transaction.
        do_more_stuff()
