Django和APScheduler在同一个Postgres上未能进行测试

Question

在我的项目代码中。我Django 1.11和APScheduler 3.3.1与Postgres 9.6

一起运行

问题出在完整的测试期间。在Django完成迁移之前，APScheduler命中数据库Postgres。

在我的OSX笔记本电脑上没有这个问题。

有什么技巧可以避免这个问题吗？

更新

models.py

from apscheduler.jobstores.sqlalchemy import SQLAlchemyJobStore
from apscheduler.schedulers.background import BackgroundScheduler

schd_inst = BackgroundScheduler(jobstores={
    'default': SQLAlchemyJobStore(
        url=settings.DATABASE_URL,
        tablename='apscheduler_jobs'
    )
})

try:
     schd_inst.start()
 except SchedulerAlreadyRunningError:
     logger.info(str(SchedulerAlreadyRunningError))

class MailAPIScheduler(DirtyFieldsMixin, AbstractSoftModelController):
    dealer = models.ForeignKey(Dealer, on_delete=models.CASCADE)
    api_url = models.URLField()
    schedule_time = JSONField(default={'hour': 0, 'minute': 0})  # 24hr e.g. {'hour': 13, 'minute': 3}
    parameters = JSONField()  # {'key': 'api-key', 'value': '123'}
    summary_email_receivers = ArrayField(
        models.EmailField(blank=True),
        blank=True
    )
    schd_id = models.UUIDField(default=uuid.uuid4, unique=True)  # uuid gen at python code not database level

settings.py

LOCAL_APPS = [
    ...,
    'myapp',
    ...
]

错误：
