How do you debug Mako templates?

Question

So far I've found it impossible to produce usable tracebacks when Mako templates aren't coded correctly.

Is there any way to debug templates besides iterating for every line of code?

Answer 1

Mako actually provides a VERY nice way to track down errors in a template:

from mako import exceptions

try:
    template = lookup.get_template(uri)
    print template.render()
except:
    print exceptions.html_error_template().render()
