rails 生成迁移 table 名称命令未在 db/migrate 中创建迁移

Question

我是运行 $ rails generate migration Tablename 命令提示符中的命令。我应该在 db/migrate 中看到新创建的 table 吗？我是 rails.

的新人

我可以看到以下错误：

Should I see the newly created table in db/migrate?

与 $ rails generate migration Tablename 无关。您将需要配置迁移，以便创建 table。这是一个很大的话题，因此请前往 guides 阅读有关生成迁移的内容。
