from pyramid.request import Request
from pyramid.i18n import get_localizer
class MyRequest(Request)
def translation_activate_language(self, culture):
if self._LOCALE_ == culture:
return self.localizer
self._LOCALE_ = culture
del self.localizer
return get_localizer(self)
would be better done in 1.3+ without subclassing request as
def translation_activate_language(request, culture):
if request._LOCALE_ == culture:
return request.localizer
request._LOCALE_ = culture
del request.localizer
return get_localizer(request)
config.set_request_property(translation_activate_language)
