Hi all
I'm migrating a small static website I developed with Jinja, to
Jinja2. I have a base template file, and a file for each page,
together with a python script which simply loads each file and renders
it to html.
I have some common files which I import & include. I'm hitting an
error which I don't understand.
without putting up the whole scheme, I have a base file like:
#------- base.tmpl
{% import "include/macros.incl" as helpers %}
{% import "include/quotes.incl" as quotes %}
{% block content %}
{% endblock %}
#---------------
and an inherited file like
# --------------- index.tmpl
{% extends "base.tmpl" %}
{% block content %}
{% include "include/inc1.incl" %}
{% endblock %}
#-----------------------
now the included file inc1.incl attempts to use macros previously
imported from the 'macros' file:
#---------------- macros.html
{% macro shorthline() %}
*** definition here ***
{% endmacro %}
# ------------ include/inc1.incl
{{ helpers.shorthline() }}
#-------------------
When I attempt to render this I get an error like:
File "/usr/lib/python2.4/site-packages/Jinja2-2.1dev_20081012-py2.4-
linux-i686.egg/jinja2/environment.py", line 332, in getattr
return getattr(obj, attribute)
File "/usr/lib/python2.4/site-packages/Jinja2-2.1dev_20081012-py2.4-
linux-i686.egg/jinja2/runtime.py", line 403, in
_fail_with_undefined_error
raise self._undefined_exception(hint)
jinja2.exceptions.UndefinedError: 'helpers' is undefined
Strangely (to me) I can prevent this by invoking the macro in the
higher template, which makes me think that is something to do with
caching:
# --------------- index.tmpl ------ this one works
{% extends "base.tmpl" %}
{% block content %}
{{ helpers.shorthline() }}
{% include "include/inc1.incl" %}
{% endblock %}
#-----------------------
however it doesn't seem to be solved by the 'with context' feature.
I'm sure I'm missing something simple here - can anyone help me
realise what it is?
Thanks
J^n
