Mako templates use old version until I manually update template files

Question

I periodically get this problem where all of a sudden mako is using old versions of templates, and it's not until I manually go and update the template files that they'll use the current version. I'm using

./manage.py runserver

I think it's usually after I update using source control, but it's intermittent, and I can't reliably reproduce the problem.

Answer 1

It kinda feels like there some caching going on. You don't give a very specific description of the process, so it's hard to go any deeper than that.

Answer 2

In your settings.py file you can use the MAKO_TEMPLATE_OPTS setting to specify where the temporary compiled templates go.

import os
import tempfile
MAKO_TEMPLATE_OPTS=dict(input_encoding='utf-8',
                        module_directory=os.path.join(
    tempfile.gettempdir(),
    os.environ.get('LOGNAME', 'unknown_user'),
    'mako'))

This will put them somewhere like /tmp/dsmith/mako

You can use different folders for different projects to make sure they don't overlap. Also, if you notice the problem after a source control update or something you can just clear out the cached folder.
