jinja2 for setting module parameters

I have difficulty using jinja2 combined with cron module in the following way:

  • cron: name=test job=“abc {{ data | filter_x(‘a’) | filter_y(‘b’) }} edf”

I tried various combinations, but either the jinja2 template isn’t expanded, or I am seeing errors parsing.

Any ideas how to make something like this work? Thanks.

I assume filter_x and filter_y are plugins you wrote?

Yes, I wrote some additional plugins and put them in ansible/lib/runner/filter_plugins/core.py

Thanks.

Hard to say what you error is without seeing the plugin.

Perhaps you could paste it?

Ah, thanks for the hint…

I wrote a new filter function but didn’t register it in the end. Is there a way to make such errors more obvious? Like fail the execution and tell me jinja2 template expansion failed - currently the unexpanded template is directly used as the output…

Thanks.

Using a filter that doesn’t exist should generate an error, that I would definitely like a bug report on if you are not seeing that behavior in 1.7.X.

Thanks!
