Merge List of Dictionary using ansible - json

Question

I am trying to merge two list of dictionaries.
"my_name":
[ {
"name": "xyz",
"number": "123" },
{
"name": "abc",
"number": "456"
}
]
"my_address":
[ {
"name": "abc",
"address": "smith street" },
{
"name": "xyz",
"number": "ray street"
}
]
Required Output:
merged:
[ {
"name": "abc",
"address": "smith street",
"number": "456" },
{
"name": "xyz",
"address": "ray street",
"number": "123"
}
]
I tried using combine but it would just combine the last item.
set_fact:
merged: "{{ my_name | combine(my_address) }}"
"merged":
[
{
"name": "xyz",
"number": "ray street",
"number": "123"
}
]
i used the debug module. debug: msg: "{{ my_name| list_mergeby(my_address,'name')}}" The error was: template error while templating string: no filter named 'lists_mergby,

Answer 1

For example, given the fixed my_address
- hosts: localhost
vars:
my_name:
- name: xyz
number: '123'
- name: abc
number: '456'
my_address:
- name: abc
address: smith street
- name: xyz
address: ray street
merged: "{{ [my_name, my_address]|community.general.lists_mergeby('name') }}"
tasks:
- debug:
var: merged
gives (abridged)
merged:
- address: smith street
name: abc
number: '456'
- address: ray street
name: xyz
number: '123'
