我最近开始尝试在轨道上使用红宝石，我不确定在轨道上是什么脚手架。
说我运行这个命令： rails生成scaffold idea name：string description：text picture：string
除了在项目目录中创建新文件外，它到底做了什么？它是否为数据库创建了一个表？
非常感谢。

查看scaffolding上的Rails指南。
当您使用generate scaffold命令时，您将创建一个迁移（在运行rake db:migrate时将创建一个表），视图，css，脚本文件，初始测试等。术语＆＃34;脚手架的字面含义＆＃34; as＆＃34;构建某物的结构＆＃34;和脚手架开始有很大意义。

Description:
Scaffolds an entire resource, from model and migration to controller and
views, along with a full test suite. The resource is ready to use as a
starting point for your RESTful, resource-oriented application.
Pass the name of the model (in singular form), either CamelCased or
under_scored, as the first argument, and an optional list of attribute
pairs.
Attributes are field arguments specifying the model's attributes. You can
optionally pass the type and an index to each field. For instance:
'title body:text tracking_id:integer:uniq' will generate a title field of
string type, a body with text type and a tracking_id as an integer with an
unique index. "index" could also be given instead of "uniq" if one desires
a non unique index.
As a special case, specifying 'password:digest' will generate a
password_digest field of string type, and configure your generated model,
controller, views, and test suite for use with Active Model
has_secure_password (assuming they are using Rails defaults).
Timestamps are added by default, so you don't have to specify them by hand
as 'created_at:datetime updated_at:datetime'.
You don't have to think up every attribute up front, but it helps to
sketch out a few so you can start working with the resource immediately.
For example, 'scaffold post title body:text published:boolean' gives
you a model with those three attributes, a controller that handles
the create/show/update/destroy, forms to create and edit your posts, and
an index that lists them all, as well as a resources :posts declaration
in config/routes.rb.
If you want to remove all the generated files, run
'rails destroy scaffold ModelName'.
Examples:
`rails generate scaffold post`
`rails generate scaffold post title:string body:text published:boolean`
`rails generate scaffold purchase amount:decimal tracking_id:integer:uniq`
`rails generate scaffold user email:uniq password:digest`
