问题描述

我有一组 Sequelize 模型.我想使用迁移，而不是数据库同步.

I have a set of Sequelize models. I want to use migrations, not DB Sync.

Sequelize CLI 似乎能够做到这一点，根据 这篇文章:当您使用 CLI 生成模型时，您还将免费获得迁移脚本."

Sequelize CLI seems to be able to do this, according to this article: "When you use the CLI for the model generation, you will gain the migration scripts for free as well."

推荐答案

如果您不想从头开始重新创建模型，可以使用以下 CLI 命令手动生成迁移文件:

If you don't want to recreate your model from scratch, you can manually generate a migration file using the following CLI command:

sequelize migration:generate --name [name_of_your_migration]

这将生成一个空白的骨架迁移文件.虽然它不会将您的模型结构复制到文件中，但我确实发现它比重新生成所有内容更容易、更干净.注意:确保从迁移目录的包含目录运行命令；否则 CLI 会为你生成一个新的迁移目录

This will generate a blank skeleton migration file. While it doesn't copy your model structure over to the file, I do find it easier and cleaner than regenerating everything. Note: make sure to run the command from the containing directory of your migrations directory; otherwise the CLI will generate a new migration dir for you
