Plugin and YAML configuration file

Hello,

Using an external YAML file for storing static datas is cool. And doing so in a basic Rails application is easy using in config/initializers/load_config.rb such: CONFIG = YAML.load_file("#{RAILS_ROOT}/config/config.yml") ...after what datas can be called in application.rb with CONFIG['something'].

But how can we load the YAML configuration file of a plugin (in its controller for instance)? For example if my plugin is in vendor/plugins/my_plugin and its YAML file is in vendor/plugins/my_plugin/config.yml?

Well you can have your plugin's code do anything you want, including read in such a yaml file if you want.

And I have an other question about this topic: is that possible to

complet the Rails internationalization's YAML files stored in config/locales/ using a additionnal YAML file into the plugin (in order to generate dynamic flash messages for instance in plugin's controllers, like so: flash[:error] = t(there_is_an_error))?

You could try adding the appropriate folder(s) to the i18n load path.

Thank you for your answer, Frederick.

Is there an example of plugin using those mechanisms?

Not that I've seen, but then I haven't looked. The rails I18n guide probably discusses the i18n load path stuff and the configuration stuff should be straight forward - loading some yaml and assigning it to a constant isn't going to be radically different just because a plugin is involved.
