java - Retrieve active locale in Grails application

Question

I know I can use the "lang" parameter to automatically change the current locale as described in the docs, but how do I track those changes, for example to update the language stored in the current user domain object?

request.locale does not work, since it does not reflect the changes done via "?lang=xx"

Answer 1

Within your controller you can obtain the locale using the RequestContextUtils.

import org.springframework.web.servlet.support.RequestContextUtils as RCU

Then to resolve the locale for the request:

RCU.getLocale(request)
