Subject: [Locale-dev-en] Localized views are not working correctly.
Message-ID: <49FA439C.9010706@snowy-owl.com>

I'm using locale-rails-2.0.1 (along with the rest of the 2.0.1 gettext 
family of gems) and have the po/mo files working fine with gettext. The 
locale code seems to be detecting my web browser locale okay.

The problem is that my view files are not being properly handled. Here's 
an example.

Set the web browser to a locale of de_DE for German.

I'm using an initializer like this:

# This file contains configurable setting for Internationalization 
(i18n) support.
#
# Tell the I18n library where to find your translations
I18n.load_path += Dir[ File.join(RAILS_ROOT, 'locale', '*.{rb,yml}') ]

# Tell the supported locales. This is the one of additional setting by 
Ruby-Locale for Ruby on Rails.
# If supported_locales is not set, the locale information which is given 
by WWW browser is used.
# This setting is required if your application wants to restrict the 
locales.
I18n.supported_locales = Dir[ File.join(RAILS_ROOT, 'locale', 
'*.{rb,yml}') ].collect{|v| File.basename(v, ".*")}.uniq

# Tell the default locale. If this value is not set, "en" is set.
# With this library, this value is used as the lowest priority locale
# (If other locale candidates are not found, this value is used).
I18n.default_locale = "en"

In my locale directory underneath RAILS_ROOT I have subdirectories named 
en, de, and ja.

My understanding of the above initializer code is that it will set the 
I18n.supported_locales to be en, de, and ja. This is what I want.

It is also my understanding that if I set my browser locale to be de_DE 
then after checking the values for supported_locales the current locale 
would be 'de' rather than 'de_DE'. My observations of actual behavior of 
the code show me that I'm wrong and that the Locale.current value is 
actually 'de_DE'.

So this is all background information so far.

Here's what is really strange.

I have view files named:

index.html.erb
index_de.html.erb
index_ja.html.erb

When my browser is set to a language other than English, either German 
or Japanese, then I continue to see the Enligsh views.

By experimentation I have discovered that if I change the file name from 
index_de.html.erb to index.de.html.erb I then actually get the German 
view delivered to my web browser.

BUT, the MIME type of the view is unknown rather than being 'text/html' 
and as a result my web browser will not display the view. Depending on 
the browser it either downloads it or has no idea what to do with the data.

Something is broken here. The rails locale howto page on yotabanana 
clearly specifies the file naming convention as index_de.html.erb but 
that doesn't actually work. index_de_DE.html.erb doesn't work either, I 
tested that too.

I either need to have the proper filenames work correctly or else need 
to figure out how to get the proper MIME type associated with files 
using the index.de.html.erb naming convention.

Thanks for any help or insight that can be offered!
