Why is deep_symbolize_keys not available within application.rb (undefined method `deep_symbolize_keys'' for Hash)
If there is a better way to do this I am open: I am trying to load a yaml
config file which holds application settings (which happens to be shared
between the main app and an engine).
class Application < Rails::Application
config_file = "#{Rails.root}/config/config.yml"
if File.exists?(config_file)
::APP_CONFIG YAML.load_file(config_file)[Rails.env].deep_symbolize_keys
else
puts "No config.yml file found, run ''rails g
blog_engine:install''"
end
....
end
The file loads if I use #symbolize_keys, but Hash#deep_symbolize_keys is not
available at this point. I know I could iterate the hash myself and do this
but of course would prefer not to and makes me wonder if there is an
alternative way to load such a config file and have the values accessible
within environment.rb so that I can assign the value.
Thanks,
David

Ok, so it looks like I need ActiveSupport::CoreExtensions::Hash. A bit confused as at the top of application.rb there is * require ''rails/all'' *, so I would think this should be included but is not. ActiveSupport is loaded but not CoreExtensions.

A quick recursive grep through all of my gems located the offender: i18n, of all things. While ActiveSupport has Hash.deep_symbolize_keys defined on the master branch on Github, that hasn''t made into the latest release (3.2.9). So for now, require ''i18n/core_ext/hash'' will do the job nicely. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
