It’s common requirement when we work on some portal – we need to provide support for various languages.

how to switch to a different language taking an advantage of GRAILS<\/h2>\n

On your view (gsp) page add following – <\/p>\n

\r\n<%\r\nString targetUri = (request.forwardURI - request.contextPath);\r\n%>\r\n English<\/g:link>\r\n French<\/g:link>\r\n Spanish<\/g:link>\r\n.....\r\n.....\r\n<\/pre>\n
I just wanted to give you a rough idea. But you can create a custom tag for this – depending upon your requirement.<\/p>\n
Now the trick here is to send parameter with name “lang”. And GRAILS automatically recognizes it and set locale itself.
\nFollowing is the code at server side (controller\/action).<\/p>\n
\n
\r\n\/\/import org.springframework.context.i18n.LocaleContextHolder\r\n\/\/import org.springframework.web.servlet.support.RequestContextUtils as RCU;\r\n\r\nclass LangController {\r\ndef lang = {\r\n       String targetUri = params.targetUri ? params.targetUri : \"\/\"\r\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 \/\/ String language = params.lang ? params.lang : 'en'\r\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 \/\/ LocaleContextHolder.setLocale(new Locale(language))\r\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 \/\/ RCU.getLocaleResolver(request).setLocale(request, response, new Locale(language))\r\n       redirect(uri: targetUri)\r\n}\r\n}\r\n<\/pre>\n<\/blockquote>\n
If you notice above, I have commented out few lines (with the help of grails internal implementation, we need to do nothing explicitly to switch to a different language). <\/p>\n
So in SINGLE LINE:<\/strong><\/p>\n
\r\nBase URL: http:\/\/example.com\/cont\/act\/id  \r\nLocale specific URL: http:\/\/example.com\/cont\/act\/id?lang=fr \r\n<\/pre>\n
Hope it helps!
