将Rails置于现有数据库之上 [英] Putting Rails over top of an existing database

问题描述

我有一个用PHP/MySQL(具体来说是symfony)编写的应用程序，(可能)想在Rails中重写.我知道如何为尚不存在的表创建脚手架，但是如何让Rails读取现有的表结构并基于该结构创建脚手架?

I have an application written in PHP/MySQL (symfony, to be specific) that I'd (potentially) like to rewrite in Rails. I know how to create scaffolding for tables that don't exist yet, but how do I get Rails to read my existing table structure and create scaffolding based on that?

更新:事实证明，我可以运行以下命令来让Rails为我生成模型:

Update: it turns out I can run the following command to get Rails to generate models for me:

rails generate scaffold Bank --no-migration

但是它没有给我表格.我希望能给我表格的东西.

But it doesn't give me forms. I would prefer something that gives me forms.
