我正在使用Rails 4,我想使用自定义配置功能,如下所述:
http://guides.rubyonrails.org/configuring.html#custom-configuration
我创建了以下YAML文件(config\prefs.yml
):
development:
password: test
我将此添加到我的config/application.rb
:
module MyApp
class Application < Rails::Application
# ...
config.x.prefs = Rails.application.config_for(:prefs)
end
end
当我进入rails控制台时,我明白了:
> Rails.configuration.x.prefs
=> {}
为什么Rails没有正确加载配置?

我在猜测以下内容:
config\prefs.yml
,因此不知道需要重新加载环境。如果我没错,您只需要使用以下代码创建初始化程序:
Spring.watch "config/prefs.yml"
当然,每次更改配置时,您都必须重新加载控制台。我已经成功地重现并解决了你的问题,所以我希望这会有所帮助。

我在我的机器上尝试你的代码并且工作正常我认为你在config/application.rb
中做的配置可能有问题,或者你需要用reload命令重新加载rails控制台reload!
我config/application.rb
require File.expand_path('../boot', __FILE__)
require 'rails/all'
# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)
module WSApp
class Application < Rails::Application
# Settings in config/environments/* take precedence over those specified here.
# Application configuration should go into files in config/initializers
# -- all .rb files in that directory are automatically loaded.
# Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
# Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
# config.time_zone = 'Central Time (US & Canada)'
# The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
# config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
# config.i18n.default_locale = :de
# Do not swallow errors in after_commit/after_rollback callbacks.
config.active_record.raise_in_transactional_callbacks = true
config.x.prefs = Rails.application.config_for(:prefs)
end
end
您的文件prefs.yml
development:
password: test
这是结果
