如何在烧瓶迁移中重命名表

如何解决如何在烧瓶迁移中重命名表

我有一个名为 company 的模型，我想将其重命名为 accounts 并且其中有一些数据，但是每当我在制作后运行 flask migrate 命令时模型名称的变化，它实际上创建了这个迁移文件：

"""empty message

Revision ID: ead37a7b46e2

正如您在迁移文件中看到的，它使用了 op.drop_table('company')，因此我收到外键约束错误。我认为，而不是这些，它应该使用类似 rename table 命令的东西。

任何人都可以在这里帮助我吗，我如何使用烧瓶迁移重命名表？
