Django继续应用迁移

编程问答 2022-06-12

问题描述

这让我发疯了：迁移时，我的Django（3.1.1）完成了任务，但似乎却忘记了。 如果我再次迁移，它将停止，因为它正在尝试重新应用迁移。

情况示例：

  • 我删除了db.sqlite3
  • 我将所有内容都放入应用程序/迁移中（不包括 init ）
  • 我正在进行makemigrations：没问题。
  • 我进行迁移：没问题。
  • 我再次运行迁移：失败（django.db.utils.OperationalError：表“ django_content_type”已存在）

仅确保我已执行“ migrate --plan”，确认它打算应用刚刚执行的迁移。我在这里想念什么？
