In a Django template, I need to transanlate some strings to a specific language (different from current one).

I would need something like this:

{% ta

This a modified version of Zalew's code which allows template's variable for the locale parameter:

from django.utils import translation
from django.template import Library, Node,  Variable, TemplateSyntaxError
register = Library()

class TransNode(Node):
    def __init__(self, value, lc):
        self.value = Variable(value)
        self.lc =  Variable(lc)

    def render(self, context):
        translation.activate(self.lc.resolve(context))
        val = translation.ugettext(self.value.resolve(context))        
        translation.deactivate()
        return val

def trans_to(parser, token):
    """ 
    force translation into a given language
      usage : {% trans_to "string to translate" locale %}
    """
    try:
        tag_name, value, lc = token.split_contents()
    except ValueError:
            raise TemplateSyntaxError, '%r tag usage: {%% trans_to "string to translate" locale %%}' % token.contents.split()[0]
    return TransNode(value, lc)

register.tag('trans_to', trans_to)
