Parse json value when value contains a string in ansible - json

Question

This ansible playbook works
---
- hosts: localhost
gather_facts: False
vars:
jq: "[?contains(name, 'Pizza')]"
json: |
[{
"name": "Ted's Sub Shop - 720895714701",
"templateid": "24632"
},
{
"name": "Ted's Pizza - 720895714702",
"templateid": "24663"
}]
tasks:
- name: DEBUG
debug:
msg: "{{ json | from_json | json_query(jq) }}"
It returns the following
ok: [localhost] => {
"msg": [
{
"name": "Ted's Pizza - 720895714702",
"templateid": "24663"
}
]
}
I need to take it a few steps further and when the value of name contains Pizza I need it to return just the 12 digit number on the end. So the return output would look like this
ok: [localhost] => {
"msg": "720895714702"
}
Thoughts?

Answer 1

you could try
- name: testplaybook jinja2
hosts: localhost
gather_facts: no
vars:
json: |
[{
"name": "Ted's Sub Shop - 720895714701",
"templateid": "24632"
},
{
"name": "Ted's Pizza - 720895714702",
"templateid": "24663"
}]
tasks:
- name: DEBUG
debug:
msg: "{{ json | from_json | selectattr('name', 'contains' , 'Pizza')
| map(attribute='name')
| map('regex_replace', '^.*?(\\d*)$', '\\1')}}"
result:
ok: [localhost] => {
"msg": [
"720895714702"
]
}

Answer 2

It might be more efficient to add an attribute. For example the declaration below
json_id: "{{ json|zip(id_hash)|map('combine')|list }}"
id_hash: "{{ id_list|
map('community.general.dict_kv', 'id')|list }}"
id_list: "{{ json|
map(attribute='name')|
map('split', '-')|
map('last')|
map('int')|list }}"
expands to
json_id:
- id: 720895714701
name: Ted's Sub Shop - 720895714701
templateid: '24632'
- id: 720895714702
name: Ted's Pizza - 720895714702
templateid: '24663'
Then, the usage is trivial. For example
- debug:
msg: "{{ json_id|
selectattr('name', 'contains' , 'Pizza')|
map(attribute='id')|list }}"
gives
msg:
- 720895714702
The same result gives also json_query below
- debug:
msg: "{{ json_id|
json_query('[?contains(name, `Pizza`)].id') }}"
