Bug in include_vars or jinja2

[DomaNitro]

For the last month I have been trying convert my v1 action plugin to v2 with no luck.

https://groups.google.com/forum/#!topic/ansible-devel/9-i8uIj9E5g

So Brian suggested to use default include_vars with a loop. So decided to try to use ansible built in modules. but the same issue came up that I had in my custom module.

test.yml

---

- name: Test include_vars template 

  hosts: all

  connection: local

  gather_facts: False

  vars:

    common_var: "my var is defined"

  tasks:

    - name: Debug common_var

      debug: var=common_var

    - name: Include var1.yml

      include_vars: "{{ item }}"

      with_items:

        - "var1.yml"

      register: foo_result

    - name: Debug results

      debug: 

        var=foo_result.results

    - name: Compile a list 

      set_fact: 

        compiled_list="{{ foo_result.results | map(attribute='ansible_facts') | list }}"

    - name: debug compile list

      debug: var=compiled_list

 var1.yml

---

var1:

   mysyste: "1"

   my_var: "{{ common_var }}"

to run 

ansible-playbook -i 127.0.0.1, test.yml

The results

TASK [Debug common_var] ********************************************************

ok: [127.0.0.1] => {

    "common_var": "my var is defined"

}

TASK [Debug results] ***********************************************************

ok: [127.0.0.1] => {

    "foo_result.results": [

        {

            "_ansible_no_log": false,

            "ansible_facts": {

                "var1": {

                    "my_var": "{# common_var #}",

                    "mysyste": "1"

                }

            },

            "invocation": {

                "module_args": {

                    "_raw_params": "var1.yml"

                },

                "module_name": "include_vars"

            },

            "item": "var1.yml"

        }

    ]

}

TASK [debug compile list]

ok: [127.0.0.1] => {

    "compiled_list": [

        {

            "var1": {

                "my_var": "{# common_var #}",

                "mysyste": "1"

            }

        }

    ]

}

 Ansible fails to substitute variable in V2. the above code works with V1, So second level substitution does not work. The variable appears as a Jinja2 comment"{# common_var #}" instead of "my var is defined"

I'm not sure that what you are doing is right, no need to access
through facts, which would prevent it from templating (security
issue).
This example shows that the variable substitution DOES work, as long
as you access it directly.

vars.yml
composed_var: "{{test1}}"

play:
---
- hosts: localhost
gather_facts: false
vars:
test1: [1,2,3]
tasks:

- include_vars: "{{item}}"
with_items:
- vars.yml

- debug: var=composed_var


output:
_____________________
< TASK [include_vars] >
---------------------
ok: [localhost] => (item=vars.yml)
______________
< TASK [debug] >
--------------
ok: [localhost] => {
"composed_var": [
1,
2,
3
]
}

Thank you for your reply.

The objective is to compile a list of variables from files in a directory without using the merge behaviour. In my example I use with_items but it should be with_fileglob

var1.yml

  myvar: "example1"

var2.yml

  myvar: "example2"

var3.yml

  myvar: "example3"

compiled_list:

  - myvar: "example1"

  - myvar: "example2"

  - myvar: "example3"

Since the templating does not happen facts any more. And I dont have the option to enable merge behaviour.

Any other alternative ?
