Ok, I've fixed it using kwargs (although it's more verbose than its
equivalente in Django templates).
Filter:
@contextfilter
def render(context, value, **kwargs):
"""
Renders the filtered value as a string template, using the context
and environment of the caller template.
"""
if kwargs:
kwargs.update(context)
ctx = kwargs
else:
ctx = context
#we render the string as its own template
mini_template = _environment.from_string(value)
return mini_template.render(ctx)
Usage:
{% for user in list_of_users %}
{{ greetings[user.locale]|render(user=user) }}
{% endfor %}
Thank you anyway, and please tell me if there is a way to avoid using
kwargs each time (I've hundreds of template files to update and test!)
