how can I achieve dynamic namespace imports in pylons / mako?

Question

I am using pylons with mako as templating engine and I have a template which uses

<%namespace name="foo" file="../bar.html"/>

and

${foo.someFunction()}

to call someFunction(). This way it is working correctly, but now I need the file "../bar.html" to be changeable dynamically like:

<%namespace name="foo" file="${c.filename}"/>

where c.filename is set in the controller. This way it isn't working and I get the following exception:

NameError: global name 'c' is not defined

Everywhere else in the template ${c.filename} is working correctly.

Does anybody know how I can achieve this import dynamically?

Thanks in advance, ashiaka

It's working when I use:

<%namespace name="foo" file="${context['tmpl_context'].filename}"/>

respectively

<%namespace name="foo" file="${context['c'].filename}"/>
