Translate email to a specific language

edit

Hi, well. I still couldn't translate it, but I think I'm near :)

What I did was copy the language function from Django 1.5 version to a new file in askbot/templatetags directory (askbot 0.7.48).

But when I try to import the template, it fails with this message:

TemplateSyntaxError: Encountered unknown tag 'language'. Jinja was looking for the following tags: 'endblock'. The innermost block that needs to be closed is 'block'.

This is what I have: In instant_notification.py:

{% block subscription %}
{% load i18n_customized %}

{% language "es" %}
    Hello World
{% endlanguage %}
{%endblock%}

And I've got a i18n_customized.py with the function:

@register.tag
def language(parser, token):
    """
    This will enable the given language just for this block.

    Usage::

    {% language "de" %}
    This is {{ bar }} and {{ boo }}.
    {% endlanguage %}

    """
    ... (the same code as in i18n.py) ...
    return LanguageNode(nodelist, language)

Also, I tried with

register.tag('language', language)

I debugged the code and the function is registered in the system.

For what I see, is something related to Jinja, but I don't know how to resolve it.

Any help is welcome
