Django-apscheduler的安装后没有表格生成，重新迁移
1，CMD,查看已经执行的migrations
python manage.py showmigrations
2，重置 app=django_apscheduler
python manage.py migrate --fake django_apscheduler zero
再执行 python manage.py showmigrations，你会发现 文件前的 x 变成了
3,重新migrate
python manage.py migrate --fake-initial
output：

Django-apscheduler的安装后没有表格生成，重新迁移
1,新建app=scheduler
python manage.py startapp scheduler
2,将...\site-packages\django_apscheduler\models.py里的表格设置内容，全部复制到
app=scheduler 目录内的models.py,并且都改名，例如
DjangoJob 改名为 DjangoJob2
DjangoJobExecutionManager 改名为 DjangoJobExecutionManager2
否则，会报错：(models.E032) constraint name 'unique_job_executions' is not unique among models: django_apscheduler.DjangoJobExecution, scheduler.DjangoJobExecution.
DjangoJobExecution 改名为DjangoJobExecution2
否则会报错：(models.E032) constraint name 'unique_job_executions' is not unique among models: django_apscheduler.DjangoJobExecution, scheduler.DjangoJobExecution.
3，python manage.py makemigrations 迁移
Migrations for 'scheduler':
scheduler\migrations\0001_initial.py
-
Create model DjangoJob2
-
Create model DjangoJobExecution2
-
Create constraint unique_job_executions2 on model djangojobexecution2
4，python manage.py migrate
如果跳过3，会遇到Your models in app(s): 'scheduler' have changes that are not yet reflected in a migration, and so won't be applied.
Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them.
