When exactly is the locale changed when using the lang parameter?

Rate this Message:
Hello, on my web-application I would like to setup a custom URL
mapping that contains the locale to be used in the URL. Eg, www.example.com/en/, www.example.com/fr for French, etc. That way the URL contains the locale information which is nice for bookmarking etc. I made up the following URL mapping: "/$lang?/about" { controller= "main" constraints { lang(matches:/[a-z]{2}/) } action = "about" } Unfortunately, it is not working, the locale is not changed (on www.example.com/fr/about/ ). If I manually specify the ?lang parameter at the end of the URL it works though. This had led me to believe that the "locale switching", based on the lang parameter, is maybe ran before the URL mapping, or it does not use the lang parameter as set by the URL mapping code in params. How should I proceed then to achieve what I want? In a Filter maybe? On a sidenote, the Grails guide says that forcing the locale via the lang parameter sets up a cookie that remembers the choice. I sniffed requests with Firebug and found no trace of such a cookie, so I guess it is stored within the session? Can someone confirm? As I will be essentially forcing the lang parameter every time with my approach, I hope that the locale switching code is not heavy - does someone know about this?

The lang switching relies on the Spring infrastructure and doesn't
read the Grails params object, but really it should. Please raise a feature request in jIRA Cheers On Wed, May 14, 2008 at 10:08 PM, Jean-Noël Rivasseau <elvanor@...> wrote: > Hello, on my web-application I would like to setup a custom URL > mapping that contains the locale to be used in the URL.

Done,
http://jira.codehaus.org/browse/GRAILS-2951 I've looked at the Spring docs to understand how this worked, and until the JIRA is fixed I came with a simple workaround in a filter applying to all controllers: if (params["lang"]) { def localeResolver = RequestContextUtils.getLocaleResolver(request); def locale = new Locale(params["lang"]); localeResolver.setLocale(request, response, locale); } Can you confirm, Graeme, that the LocaleResolver implementation used by Grails is the SessionLocaleResolver? (not very clear from the docs). Also, while I was playing with the URL mappings I was wondering a few things: In particular, does the constraints allow the URL mapper resolver to discriminate on a optional parameter? Eg, for the mapping: "/$lang?/$controller/$action?" { constraints { lang(matches:/[a-z]{2}/) } } will the code checks if I have a 2 letter string after the first slash, in that case fill the $lang parameter, and in the other case assume the $lang parameter is not present? I am not sure if such advanced conditional mappings currently work with Grails.

I came to the same conclusion. However apparently if you put two mappins, one with the lang parameter and the other without, it works fine. So it's ok for me Thanks Peter, Jean-Noel --------------------------------------------------------------------- To unsubscribe from this list, please visit: http://xircles.codehaus.org/manage_email |
