Subject: Allow instantiating template dataclasses in jinja2 templates
X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=9851982d3fe395fe8e5f66247c19d81f4c82e634;p=thirdparty%2Fbind9.git

Allow instantiating template dataclasses in jinja2 templates

In some cases, the template data might need to be set directly in the
jinja2 templates using `{% set %}`. Expose the template dataclasses to
the templates so we can use these existing classes, rather than creating
ad-hoc data containers.
