如何更改 Ruby on Rails 应用程序名称？

How to change a Ruby on Rails application name?

提问by Misha Moroshko

I have a Ruby on Rails application that was created using:

我有一个使用以下方法创建的 Ruby on Rails 应用程序：

rails new old_name -d mysql

Now I want to change the application name to be new_name.

现在我想将应用程序名称更改为new_name.

Just changing the application folder name will not be enough, because the database name, for example, also has to be changed (from old_name_developmentto new_name_development). I wonder if there are other places in the automatically generated files that needs changing.

仅更改应用程序文件夹名称是不够的，因为例如数据库名称也必须更改（从 更改old_name_development为new_name_development）。不知道自动生成的文件有没有其他地方需要修改。

Is there any built in command for changing the application name ?

是否有任何用于更改应用程序名称的内置命令？

In Rails 3, there are references to the application name in the following files:

在 Rails 3 中，以下文件中引用了应用程序名称：

• config/application.rb
• config/environment.rb
• config/environments/development.rb
• config/environments/production.rb
• config/environments/test.rb
• config/initializers/secret_token.rb
• config/initializers/session_store.rb
• config/mongoid.yml (if using Mongoid)
• config/routes.rb
• config.ru
• Rakefile
• app/views/layouts/application.html.erb, in title tag

• 配置/应用程序.rb
• 配置/环境.rb
• 配置/环境/development.rb
• 配置/环境/production.rb
• 配置/环境/test.rb
• 配置/初始化程序/secret_token.rb
• 配置/初始化程序/ session_store.rb
• config/mongoid.yml（如果使用 Mongoid）
• 配置/路由.rb
• 配置文件
• 文件
• app/views/layouts/application.html.erb，在标题标签中

in Rails 3, the application class is defined in config/application.rb, and referred to in your environment files (config/environment.rb, config/environments/*.rb) and config/routes.rb. I think that's it, but you should find out pretty quickly from rails server if you missed one. :)

在 Rails 3 中，应用程序类定义在 config/application.rb 中，并在您的环境文件（config/environment.rb、config/environments/*.rb）和 config/routes.rb 中引用。我认为就是这样，但是如果您错过了一个，您应该很快从 Rails 服务器中找到。:)

• config/application.rb
• config/enviroment.rb
• config/environments/*.rb
• config/routes.rb

• 配置/应用程序.rb
• 配置/环境.rb
• 配置/环境/*.rb
• 配置/路由.rb

That said, unless you've got a very specific reason for wanting it changed, I wouldn't bother. Doesn't really affect the application in any other way.

也就是说，除非你有一个非常具体的理由想要改变它，否则我不会打扰。不会以任何其他方式真正影响应用程序。

回答by Koen.

Run the following to replace the old_name for new_name from the root of your Rails (3.0.7) project.

运行以下命令以替换 Rails (3.0.7) 项目根目录中的 new_name 的 old_name。

replace old_name new_name -- ./config/environment.rb ./config/application.rb ./Rakefile ./config/initializers/secret_token.rb ./config/environments/production.rb ./config/environments/development.rb ./app/views/layouts/application.html.erb ./config/routes.rb config.ru ./config/environments/test.rb ./config/initializers/session_store.rb

But be sure to run

但一定要跑

fgrep old_name . -iR

Or something similar first to check if there are no occurrences of old_name in your project who not should be replaced.

或类似的东西首先检查您的项目中是否不存在不应替换的 old_name 。

EDIT:

编辑：

Of course for this you need to have the replace command installed.

当然，为此您需要安装替换命令。

And take in account that your appname will be CamelCased, so maybe you have to try a few different variations, like OldName vs. NewName.

并考虑到您的应用程序名称将是 CamelCased，所以也许您必须尝试一些不同的变体，例如 OldName 与 NewName。

You might find yourself having to rename the app when wanting or having to generate a model or scaffold with the same name as the app's name. Just happened to me. Used https://github.com/morshedalam/renameon Rails 3.2.13 and no problems so far.

当想要或必须生成与应用程序名称同名的模型或脚手架时，您可能会发现自己必须重命名应用程序。刚刚发生在我身上。在 Rails 3.2.13 上使用https://github.com/morshedalam/rename，到目前为止没有问题。

To do this, I have used good old shell commands :

为此，我使用了很好的旧 shell 命令：

grep -r old_name * | cut -d: -f1 | xargs sed -i .bak 's/old_name/new_name/g'

This command replace the old_name with new_name in all file it finds the old_name. However, it creates a backup file with the extension '.bak'. Those file can be easily removed once you check everything went well.

此命令在它找到 old_name 的所有文件中用 new_name 替换 old_name。但是，它会创建一个扩展名为“.bak”的备份文件。一旦您检查一切顺利，就可以轻松删除这些文件。

The advantage of this, is that it is not 'rails version dependent'.

这样做的好处是它不是“依赖于 Rails 版本”。
