Problem trying to use a specific string with templates

Hi everyone,

I’m trying to put a string by replacing a macro in a template but the problem is that the string itself it’s being interpreted as a macro and I need to avoida that. Here are config vars and the template:

vars.yml:
log_format: “[%(asctime)s] {%(pathname)s:%(lineno)d} %(levelname)s - %(message)s”

expire: 1000

template (setting.py):
formatter = logging.Formatter(“{{ api_log_format }}”)

expire = {{expire}}

When I execute the playbook I’m getting the following error:

{‘msg’: ‘AnsibleError: ERROR! Failed to template [%(asctime)s] {%(pathname)s:%(lineno)d} %(levelname)s - %(message)s: ERROR! template error while templating string: tag name expected’, ‘failed’: True}

If I change {%(pathname)s:%(lineno)d} with for example [%(pathname)s:%(lineno)d] the problem it’s solved and the playbook continues but I can’t do that because it’s a developers request that the { and } exists in the log format.

Is there any way that I could tell ansible to ignore that specific line?

Any other idea?

I’m using ansible v1.9.2

Thanks!

Hi everyone,

   I'm trying to put a string by replacing a macro in a template but the
problem is that the string itself it's being interpreted as a macro and I
need to avoida that. Here are config vars and the template:

vars.yml:
log_format: "[%(asctime)s] {%(pathname)s:%(lineno)d} %(levelname)s -
%(message)s"

template (setting.py):
formatter = logging.Formatter("{{ api_log_format }}")
expire = {{expire}}

When I execute the playbook I'm getting the following error:

{'msg': 'AnsibleError: ERROR! Failed to template [%(asctime)s]
{%(pathname)s:%(lineno)d} %(levelname)s - %(message)s: ERROR! template
error while templating string: tag name expected', 'failed': True}

If I change {%(pathname)s:%(lineno)d} with for example
[%(pathname)s:%(lineno)d] the problem it's solved and the playbook
continues but I can't do that because it's a developers request that the {
and } exists in the log format.

There is a typo in my first email,

This line log_format: "[%(asctime)s] {%(pathname)s:%(lineno)d}
%(levelname)s - %(message)s"

should be

api_log_format: "[%(asctime)s] {%(pathname)s:%(lineno)d} %(levelname)s -
%(message)s"

Sorry

What you need to do is tell jinja2 that the value should not be parsed. To do this you can use {% raw %} ... {% endraw %} such as:

api_log_format: “{% raw %}[%(asctime)s] {%(pathname)s:%(lineno)d} %(levelname)s - %(message)s{% endraw %}”

Thank you very much, I worked, that was exactly what I needed.
