Here's the best I've got to offer. I tried pipelining filters etc but
couldn't quite get over the hump. So, back to old school loops.
- set_fact:
backup_objects: |
{% set result = [] %}
{% for obj in all_objects %}
{% set _ = result.append({'basename': obj['Key'] |
regex_replace('^' ~ prefix ~ '\\d{10}_(.*)\.pgdump', '\\1')} | combine(obj)) %}
{% endfor %}{{ result }}
The point of the "set _" line is for the side effect of appending
revised objects to the "result" list. Otherwise it's pretty straightforward.
Cheers,

Hii
I have a list of dicts, where I want to inject a number of helper keys.
I can do this with set_facts in a loop. Example playbook (hopefully
this displays OK):
---
- name:Add helper keys to list of dicts
hosts:localhost
connection:local
gather_facts:no
tasks:
- set_fact:
backup_objects:"{{ backup_objects|default([])|union(
[
item|combine(
{
'basename':item.Key|regex_replace('^'~ prefix~
'\\d{10}_(.*)\\.pgdump','\\1')
}
)
]
)
}}"
loop:"{{ all_objects}}"
loop_control:
label:"{{ item.Key}}"
- debug:var=backup_objects
vars:
prefix:backup/database/
all_objects:

This works, but in my real world use case this list is very long, so
there will be a lot of output because of each iteration. I have
already set the loop label to something less noisy.
Is there a way to add keys to a list of dicts, where those new keys
are based on an operation of another key?
thx !
Dick
