Hello!
I might be going around the problem in the wrong way, but I seem to need to
access the variable cache from a filter plugin.
I am trying to create a map filter, that can be used like so:
- name: Test Play
hosts: 127.0.0.1
connection: local
vars:
input:
- foo
- bar
data:
foo: 4
bar: 5
baz: 6
tasks:
- debug: msg="{{ input | map("{{data[__in__]}}") }}"
I am expecting it to print [4,5].
It seems that the way to solve it was to include a jinja expression as the
parameter to the filter which will be evaluated for each element of the
list, by substituting their value in place of the __in__ symbol, which I
took the liberty to hard-code.
Unfortunately for this to work I need to be able to access the variable
cache within the filter:
from ansible.utils import template
def _map(arg, expr):
vars = {}
return map(lambda x: template.template_from_string(None, expr,
dict(vars, __in__ = x), True), list(arg))
class FilterModule(object):
''' Ansible extra jinja2 filters '''
def filters(self):
return {
'map': _map,
}
This results in an error:
fatal: [127.0.0.1] => One or more undefined variables: 'data' is undefined
I have been browsing through the code for 3 hours, but could not find a way
to get a copy of all variables, similar to task.py:
https://github.com/ansible/ansible/blob/devel/lib/ansible/playbook/task.py#L225,L230
Can anyone lend a hand?
Thanks,
Akos Vandra
