Question

我正在跑步 $ rails generate migration Tablename 命令提示符中的命令。我应该在db / migrate中看到新创建的表吗？我是铁杆新手。

我可以看到以下错误：

rails generate migration TruncateUnusedTables

我应该在db / migrate中看到新创建的表吗？

不在$ rails generate migration Tablename。您需要配置迁移，以便创建表。这是一个很大的主题，因此请转到guides阅读有关生成迁移的信息。

rails generate migration table name命令不会在db / migrate中创建迁移
