I'm faced with a corner case where some devices are expected to return a
list of dictionaries but instead return a single dictionary. This creates
an error later on in ansible when a list is expected.
For instance, the device returns the file:
var:
key_1: value_11
key_2: value_21
key_3: value_31
instead of for instance:
var:
- key_1: value_11
key_2: value_21
key_3: value_31
- key_1: value_12
key_2: value_22
key_3: value_32
...
So the goal is to transform the first var into:
var:
- key_1: value_11
key_2: value_21
key_3: value_31
AFAIK, there is no ansible filters
<https://docs.ansible.com/ansible/latest/user_guide/playbooks_filters.html#transforming-dictionaries-into-lists>
to accomplish that; for instance, 'list' does not give the expected result.
Also, we cannot count on the name or number of keys as they may change.
I suppose the solution may revolve around something like that:
- set_fact:
list_var: >-
{% for key, value in var.items() %}
{{ [{key: value}] }}
{% endfor %}
when: >
(var | type_debug != 'list')
This does not give the expected result either.
Any suggestion?
