I tried to have the jinja2 decorator inside a separate file in
controllers, with no success. My other controller simply can't find
the other files inside his package. O.O.
Oh, about the discussion, web2py template system does not seems
pythonic to me, not at all. It is not pretty(python has to be pretty),
and does not enphasys logic outsite templates, as you'll run python
code directly inside the templates. This kind of approach has proven
bad in lot's of languages and systems, from php to jsp and more.
{{text|e}} <= pretty
{{escape(text)}} <= not so much
pretty
{% for stuff in other_stuff %}
do stuff with {{stuff}}
{% endfor %}
not so much
{{ for stuff in other_stuff }}
do stuff with {{=stuff}}
{{pass}}
