[Zope] Re: Change language with PTS

[Josef Meile]

Hi Peter,

First at all, I think Localizer may be easier to do this task, it has
Built-in Cookie and traversal url support. You may also define your own
language selection method. If you still want to try this with PTS, then read
the following lines.

To set the language you want with PTS, you have to set the
HTTP_ACCEPT_LANGUAGE as follows:

REQUEST.set('HTTP_ACCEPT_LANGUAGE',lang)

where lang could be 'sv'. Please note that you have to do this at the
beginning your your ZPT Template or DTML method. I have had problem when
doing this in the middle of the code.

I think cookies could also work, but I haven't tested the code myself. You
will need to set them via the request object like this:

REQUEST.RESPONSE.setCookie('lang','sv', max_age=something)
lang = REQUEST.cookies['lang']

PTS doesn't support traversal url. Anyway, you can still achieve this with
Access Rules. There is an outdated how-to that can give you an idea on how
to do this:

How To build multilingual sites with SiteAccess:
http://www.zope.org/Members/jdavid/MultilingualSiteAccess

There you will see that SiteAccess is mentioned, which is deprecated;
however, I think this Product was replaced by SiteRoot and Access Rules
(somebody correct me if I'm wrong). You may need to google about this.

As mentioned in that How-To, it was superseded by Localizer, so, you may
look at the source code of this product as well.
