Problem with local variables in Jinja2 template includes

[Mike Yumatov]

Hi

It seems there is a problem with locals in Jinja2 templates. For example, this works in vanilla Jinja2 environment, but doesn't work in ansible environment ("One or more undefined variables: 'publisher' is undefined"):

{# simplified config.xml.j2 #}
<config>
{% for publisher in item.publishers %}
{% include 'publisher.xml.j2' %}
{% endfor %}
</config>

{# simplified publisher.xml.j2 #}
<report>{{ publisher.report }}</report>

In Jinja2 local variables are passed to the new context with 'l_' prefix. This prefix is stripped in vanilla environment [1], but that is not true in case of ansible environment [2]. So in the latter case 'publisher' variable is available in 'publisher.xml.j2' template as 'l_publisher'.

Is this an intended feature, or should I fill a bug report?

There was a post about this earlier IIRC.

Jinja2 includes in Ansible are not probably well wired up, please do file a ticket.
