“Django_迁移”关系已存在

Question

我使用Django租户模式将租户分配到他们自己的模式。不久前我遇到了一个迁移问题，现在在它自己的模式上创建租户失败后，还剩下一些东西。此模式称为tiger

给出如何设置的想法；有些数据是公共的，存在于公共模式（如用户和公司）上，但其他所有数据都是特定于租户的，并且存在于自己的模式中

这是我运行迁移的方式：

(venv) david@clearpath:~/clearpath_project$ python manage.py migrate_schemas

[standard:public] === Starting migration
[standard:public] Operations to perform:
[standard:public]   Apply all migrations: admin, auth, categories, companies, contenttypes, employees, invite, memos, notifications, phone_verify, quiz, sessions, videos
[standard:public] Running migrations:
[standard:public]   No migrations to apply.

[1/5 (20%) standard:clearpath] === Starting migration
[1/5 (20%) standard:clearpath] Operations to perform:
[1/5 (20%) standard:clearpath]   Apply all migrations: admin, auth, categories, companies, contenttypes, employees, invite, memos, notifications, phone_verify, quiz, sessions, videos

[3/5 (60%) standard:aces] === Starting migration
[3/5 (60%) standard:aces] Operations to perform:
[3/5 (60%) standard:aces]   Apply all migrations: admin, auth, categories, companies, contenttypes, employees, invite, memos, notifications, phone_verify, quiz, sessions, videos
[3/5 (60%) standard:aces] Running migrations:
[3/5 (60%) standard:aces]   No migrations to apply.
[4/5 (80%) standard:tiger] === Starting migration
[4/5 (80%) standard:tiger] Operations to perform:
[4/5 (80%) standard:tiger]   Apply all migrations: admin, auth, categories, companies, contenttypes, employees, invite, memos, notifications, phone_verify, quiz, sessions, videos
[4/5 (80%) standard:tiger] Running migrations:

在schematiger中，它失败并显示：

注意：这只是回溯的开始部分

Traceback (most recent call last):
  File "/home/david/clearpath_project/venv/lib/python3.7/site-packages/django/db/backends/utils.py", line 82, in _execute
    return self.cursor.execute(sql)
psycopg2.errors.DuplicateTable: relation "django_migrations" already exists

我尝试过使用psql{}删除模式，但这没有帮助。我相信问题是因为租户仍然存在于public模式中，但我可能错了

我需要保留数据，所以不能删除数据库

有没有想过我该如何解决这个问题
