Rails 3 - 我是否使配置文件太复杂了？

我是一个简单的人 - 我只想要一个可从控制器访问的 YAML 配置文件。就这样。

首先，我创建了 config/app_config.yml，其中包含我想要的配置值。到目前为止，一切都很好。

然后，我创建了 lib/app_config.rb，其中包含：

module AppConfig
  def self.config
    @@config ||= {}
  end

  def self.config=(config)
    @@config = config
  end
end

最后，我创建了 config/initializers/load_app_config.rb，其中包含：

# the ./ is necessary for some reason, though no examples online use it...
require './lib/app_config'

AppConfig.config = YAML.load_file("#{Rails.root.to_s}/config/app_config.yml")

我应该跳过 load_app_config .rb 一起，并以其他方式分配 AppConfig.config （可能在模块本身内部）？

看来我把事情搞得太复杂了..

I'm a simple guy— I just want a YAML config file that's accessible from controllers. That's all.

First, I created config/app_config.yml, which contains the config values I want. So far, so good.

Then, in I created lib/app_config.rb, which contains:

module AppConfig
  def self.config
    @@config ||= {}
  end

  def self.config=(config)
    @@config = config
  end
end

Finally, I created config/initializers/load_app_config.rb, which contains:

# the ./ is necessary for some reason, though no examples online use it...
require './lib/app_config'

AppConfig.config = YAML.load_file("#{Rails.root.to_s}/config/app_config.yml")

Should I skip load_app_config.rb altogether, and assign AppConfig.config some other way (perhaps inside of the module itself)?

It seems I'm making it too complicated..

我使用 Mark Bates 的 configatron，它与 AppConfig 方法相同，但它允许在 YAML 中使用 ERB 和可以帮助使用命名空间：

configatron.website_url = "http://www.mackframework.com"
configatron.email.pop.address = "pop.example.com"
configatron.email.pop.port = 110
configatron.email.smtp.address = "smtp.example.com"
configatron.email.smtp.port = 25

I use configatron by Mark Bates, it's the same as AppConfig approach, but it allows to use ERB in YAML and can help to use namespaces:

configatron.website_url = "http://www.mackframework.com"
configatron.email.pop.address = "pop.example.com"
configatron.email.pop.port = 110
configatron.email.smtp.address = "smtp.example.com"
configatron.email.smtp.port = 25

你让它变得比需要的更复杂一些。你只需要两件事：

你的配置：/config/config.yml
（应该看起来像这样，当然这些只是占位符）

development: &DEVELOPMENT
  host_name: "localhost:3000"
  api_username: [email protected]
  api_pass: password
  api_key: 12345
test:
  <<: *DEVELOPMENT
cucumber:
  <<: *DEVELOPMENT
staging:
  host_name: "my-staging-staging.heroku.com"
  api_username: [email protected]
  api_pass: password
  api_key: 12345
  s3:
    bucket: bucket-name
    access_key_id: secret_key_id
    secret_access_key: secret_key
production:
  host_name: "my-production.heroku.com"
  api_username: [email protected]
  api_pass: password
  api_key: 12345
  s3:
    bucket: bucket-name
    access_key_id: secret_key_id
    secret_access_key: secret_key

然后你的初始化程序：/config/initializers/app_config.rb

AppConfig = YAML.load(File.read(Rails.root + 'config' + 'config.yml'))[Rails.env].with_indifferent_access

现在你可以通过 AppConfig 从任何地方访问你的配置中的任何内容。例如，要在您所处的任何环境中获取主机名：

AppConfig[:host_name]

如果我们在本地运行，该值将是“localhost:3000”

You are making it a little more complicated than it needs to be. You only need 2 things:

Your conifg: /config/config.yml
(should look something like this, of course these are just placeholders)

development: &DEVELOPMENT
  host_name: "localhost:3000"
  api_username: [email protected]
  api_pass: password
  api_key: 12345
test:
  <<: *DEVELOPMENT
cucumber:
  <<: *DEVELOPMENT
staging:
  host_name: "my-staging-staging.heroku.com"
  api_username: [email protected]
  api_pass: password
  api_key: 12345
  s3:
    bucket: bucket-name
    access_key_id: secret_key_id
    secret_access_key: secret_key
production:
  host_name: "my-production.heroku.com"
  api_username: [email protected]
  api_pass: password
  api_key: 12345
  s3:
    bucket: bucket-name
    access_key_id: secret_key_id
    secret_access_key: secret_key

Then your initializer: /config/initializers/app_config.rb

AppConfig = YAML.load(File.read(Rails.root + 'config' + 'config.yml'))[Rails.env].with_indifferent_access

Now you can access anything from you config from anywhere via AppConfig. For example to grab the host name in whatever environment you are in would be:
