Remove an item from a list of dict and splitting stdout_lines - ansible

Question

Im trying to eliminate an item from a list of dicts, the one that have "No results were found":
"validar": [
{
"LPARNAME": [
"No results were found."
]
},
{
"LPARNAME": [
"server1",
"server2",
"server4"
]
},
{
"LPARNAME": [
"server3",
"server5",
"server7"
]
}
]
}
Im trying using rejectattr but is not working:
- name: clean
set_fact:
validar_: "{{ validar | rejectattr('LPARNAME', 'match', 'No results were found.') | list }}"
Also im trying to split stdout_lines of:
"output": [
{
"item": {
"Name": "CONT1"
},
"stdout_lines": [
"server1,1.05",
"server2,0.25"
]
},
{
"item": {
"Name": "CONT2"
},
"stdout_lines": [
"server3,0.05",
"server4,0.35"
]
},
{
"item": {
"Name": "PRD1"
},
"stdout_lines": [
"server4,1.15"
]
}
]
}
I got an error: {"msg": "'list object' has no attribute 'stdout_lines'"}
- name: list
set_fact:
lpar_proc: "{{ lpar_proc | default([]) + [{ 'lpar': item.[0] , 'proc': item[1] }]"
with_items: [ "{{ output.stdout_lines.split(',')[0]}}", "{{ output.stdout_lines.split(',')[1]" ]
the output expected:
Name: CONT1
vm: server1
proc: 1.05
Name: CONT1
vm: server2
proc: 0.25
... etc

Answer 1

you have list of list, so you cant use rejectattr as you do:
- name: testplaybook jinja2
hosts: localhost
gather_facts: no
vars:
validar:
- LPARNAME:
- No results were found.
- LPARNAME:
- server1
- server2
- server4
- LPARNAME:
- server3
- server5
- server7
tasks:
- name: clean
set_fact:
result: "{{ result | default([]) + [item] }}"
loop: "{{ validar }}"
when: '"No results were found." not in item.LPARNAME'
- name: set in validar
set_fact:
validar: "{{ result }}"
- name: debug
debug:
var: validar
result:
{
"validar": [
{
"LPARNAME": [
"server1",
"server2",
"server4"
]
},
{
"LPARNAME": [
"server3",
"server5",
"server7"
]
}
]
}
for the other problem:
- name: testplaybook
hosts: localhost
gather_facts: no
vars:
output:
- item:
Name: CONT1
stdout_lines:
- server1,1.05
- server2,0.25
- item:
Name: CONT2
stdout_lines:
- server3,0.05
- server4,0.35
- item:
Name: PRD1
stdout_lines:
- server4,1.15
tasks:
- name: m1
set_fact:
m1: "{{ m1 | d([]) + _p }}"
loop: "{{ output }}"
vars:
_p: "{{ [item['item']]| product(item.stdout_lines) }}"
- name: m2
set_fact:
result: "{{ result | d([]) + [_server] }}"
loop: "{{ m1 }}"
vars:
_vm: "{{ item.1.split(',')|first }}"
_proc: "{{ item.1.split(',')|last }}"
_server: "{{ item.0 | combine({'vm': _vm, 'proc': _proc}) }}"
- name: debug
debug:
var: result
result:
ok: [localhost] => {
"result": [
{
"Name": "CONT1",
"proc": "1.05",
"vm": "server1"
},
{
"Name": "CONT1",
"proc": "0.25",
"vm": "server2"
},
{
"Name": "CONT2",
"proc": "0.05",
"vm": "server3"
},
{
"Name": "CONT2",
"proc": "0.35",
"vm": "server4"
},
{
"Name": "PRD1",
"proc": "1.15",
"vm": "server4"
}
]
}

Answer 2

Given the data
validar:
- LPARNAME:
- No results were found.
- LPARNAME:
- server1
- server2
- server4
- LPARNAME:
- server3
- server5
- server7
The value of the attribute LPARNAME is a list. Use test contains instead of match. See Testing if a list contains a value
validar_: "{{ validar|
rejectattr('LPARNAME', 'contains', 'No results were found.') }}"
expands to
validar_:
- LPARNAME:
- server1
- server2
- server4
- LPARNAME:
- server3
- server5
- server7
Given the data
output:
- item:
Name: CONT1
stdout_lines:
- server1,1.05
- server2,0.25
- item:
Name: CONT2
stdout_lines:
- server3,0.05
- server4,0.35
- item:
Name: PRD1
stdout_lines:
- server4,1.1
Iterate with_subelements
- set_fact:
lpar_proc: "{{ lpar_proc|default([]) +
[item.0.item|
combine(dict(['vm', 'proc']|
zip(item.1.split(','))))] }}"
with_subelements:
- "{{ output }}"
- stdout_lines
gives
lpar_proc:
- {Name: CONT1, proc: '1.05', vm: server1}
- {Name: CONT1, proc: '0.25', vm: server2}
- {Name: CONT2, proc: '0.05', vm: server3}
- {Name: CONT2, proc: '0.35', vm: server4}
- {Name: PRD1, proc: '1.1', vm: server4}
