Ansible adding items to nested list - ansible

Question

starting data:
ok: [test#test.com] => {
"msg": {
"testdb1": {
"dbe_user_not_in_db": [
"test_user1",
"test_user2"
],
}
}
}
I currently have the following in ansible:
- name: Create dbe_pass_pairs
set_fact:
ora_sid_home_map: "{{ora_sid_home_map|combine({ item[0].key: {'dbe_pass_pairs': {item[1]: password} }}, recursive=True)}}"
loop: "{{ ora_sid_home_map | dict2items | subelements('value.dbe_user_not_in_db') }}"
vars:
password: "{{ lookup('password', '/dev/null length=10 chars=ascii_letters,digits') }}"
Which yields:
ok: [test#test.com] => {
"msg": {
"testdb1": {
"dbe_pass_pairs": {
"test_user1": "4SS2kJ7p0z",
"test_user2": "VLIzNfoaxf"
},
"dbe_user_not_in_db": [
"test_user1",
"test_user2"
],
}
}
}
Instead of dbe_pass_pairs containing dictionary items I'd like them to be a list of strings like such with a semicolon as:
ok: [test#test.com] => {
"msg": {
"testdb1": {
"dbe_pass_pairs": [
"test_user1;4SS2kJ7p0z",
"test_user2;VLIzNfoaxf"
],
"dbe_user_not_in_db": [
"test_user1",
"test_user2"
],
}
}
}
Doing something like the following just overwrite the list instead of appending:
- name: Create dbe_pass_pairs
set_fact:
ora_sid_home_map: "{{ora_sid_home_map|combine({ item[0].key: {'dbe_pass_pairs': [item[1] + ';' + password] }}, recursive=True)}}"
loop: "{{ ora_sid_home_map | dict2items | subelements('value.dbe_user_not_in_db') }}"
vars:
password: "{{ lookup('password', '/dev/null length=10 chars=ascii_letters,digits') }}"
"dbe_pass_pairs": [
"test_user2;AxL6ayeZIH"
],
Any idea how to get what I'm looking for data wise?

a solution using jinja2:
- name: Reproduce issue
hosts: localhost
gather_facts: yes
vars:
ora_sid_home_map:
testdb1:
dbe_user_not_in_db: ["test_user1", "test_user2"]
tasks:
- name: Create paswords
set_fact:
ora_sid_home_map: >-
{%- set ns=namespace(result=[], ident="", final={}) -%}
{%- set ns.ident = ora_sid_home_map |first -%}
{%- for user in ora_sid_home_map[ns.ident].dbe_user_not_in_db -%}
{%- set password = lookup('password', '/dev/null length=10 chars=ascii_letters,digits') -%}
{%- if ns.result.append(user ~ ';' ~ password) -%}{%- endif -%}
{%- endfor -%}
{{ {ns.ident: ora_sid_home_map[ns.ident] | combine({'dbe_pass_pairs': ns.result})} }}
- debug:
msg: "{{ ora_sid_home_map }}"
result:
ok: [localhost] => {
"msg": {
"testdb1": {
"dbe_pass_pairs": [
"test_user1;tPOSfCzLLq",
"test_user2;e0A92Dkuac"
],
"dbe_user_not_in_db": [
"test_user1",
"test_user2"
]
}
}
}
without jinja2:
- name: Reproduce issue
hosts: localhost
gather_facts: yes
vars:
ora_sid_home_map:
testdb1:
dbe_user_not_in_db: ["test_user1", "test_user2"]
tasks:
- name: Create paswords
set_fact:
passwords: "{{ passwords | d([]) + [data] }}"
loop: "{{ ora_sid_home_map[ident].dbe_user_not_in_db }}"
vars:
password: "{{ lookup('password', '/dev/null length=10 chars=ascii_letters,digits') }}"
data: "{{ item ~ ';' ~ password }}"
ident: "{{ ora_sid_home_map|first }}"
- name: result
set_fact:
ora_sid_home_map: "{{ {ident: data} }}"
vars:
ident: "{{ ora_sid_home_map|first }}"
data: "{{ ora_sid_home_map[ident]| combine({'dbe_pass_pairs': passwords}) }}"
- debug:
msg: "{{ ora_sid_home_map }}"
