Ansible J2 unicode

[Tom Davison]

Hi everyone.

When trying to template out a weblogic wl.properties file, I am running into a Jinja2 template problem.

Here is a snippet of code I am running into issues with:

################################################################################

# ADDITIONAL MACHINE PROPERTIES

################################################################################

ADDITIONAL_MACHINES={% for server in my_servers %}{{ server }}{% if not loop.last %},{% endif %}{% endfor %}

{% for more_servers in my_servers %}

{{ [more_servers] }}LISTEN_ADDRESS={{ ansible_nodename }}

{% endfor %}

BAD OUTPUT:

################################################################################

# ADDITIONAL MACHINE PROPERTIES

################################################################################

ADDITIONAL_MACHINES=myserver02,myserver03,myserver04,myserver05,myserver06,myserver07,myserver08

[u'myserver02']LISTEN_ADDRESS=ansible_host

[u'myserver03']LISTEN_ADDRESS=ansible_host

[u'myserver04']LISTEN_ADDRESS=ansible_host

[u'myserver05']LISTEN_ADDRESS=ansible_host

[u'myserver06']LISTEN_ADDRESS=ansible_host

[u'myserver07']LISTEN_ADDRESS=ansible_host

[u'myserver08']LISTEN_ADDRESS=ansible_host

It appears that the square brackets around the j2 variable more_servers cause rendering issues and makes python inject the unicode "u" as well as single quotes into the final output. 

EXPECTED OUTPUT:

################################################################################

# ADDITIONAL MACHINE PROPERTIES

################################################################################

ADDITIONAL_MACHINES=myserver02,myserver03,myserver04,myserver05,myserver06,myserver07,myserver08

[myserver02]LISTEN_ADDRESS=ansible_host

[myserver03]LISTEN_ADDRESS=ansible_host

[myserver04]LISTEN_ADDRESS=ansible_host

['myserver05]LISTEN_ADDRESS=ansible_host

[myserver06]LISTEN_ADDRESS=ansible_host

[myserver07]LISTEN_ADDRESS=ansible_host

[myserver08]LISTEN_ADDRESS=ansible_host

I have tried many different filters to get this to work, but just cannot get it. Filters include: to_json, to_nice_json, to_yaml, to_nice_yaml,join, replace.

Any help would be greatly appreciated!

By doing this:

{{ [more_servers] }}

You are creating a python list, and then printing it.

I think you instead want:

[{{ more_servers }}]
