Rack User Locale
A Rack module for getting and setting a user's locale via a cookie or browser default language.
Credit to these gems for pointing me in the direction I wanted to go in...
gem install rack-user-locale
In a Gemfile:
Add the following line to your Rack application
and thats it!!
Your application will now attempt to set the I18n.locale value based on the following:
- Whether a user has a
- The "HTTP_ACCEPT_LANGUAGE" value. If there are multiple values it will attempt to set the one ranked highest
- The I18n.default_locale value (basically a fallback)
The user locale detection is done on every Rack::Request, which would include all of the non Ruby/Rack actions like .css or .js files.
If you don't want this happen then you can use Rack::Static in your application and filter out which files Rack should serve up statically.
Something like this:
use ::Static, urls: ["/css", "/js"], root: "public"
This would serve anything in your public folder statically and wouldn't create a Rack::Request.
See the Rack::Static docs for more info.
use ::, accepted_locales: [:de, :en, :es, :fr, :ja, :pt, :zh] #(whatever codes you support)
If this option is supplied the users locale will either be set to one of the accepted locales in the array, otherwise it will be set to the
Should you wish to overwrite a users locale value at any point in your application, like for changing language prefs, then simple rewrite the
user-locale cookie with a new value.
If you don't want to use the default cookie name of
user-locale, you can set it to something else by passing a
use ::, cookie_name: "some-cookie-name"
