将 ansible 列表列表转换为字典列表

Question

我终于学会了如何使用

product

进行嵌套列表，但我不喜欢必须通过索引访问结果。

product

生成一个列表列表，我想要一个字典列表。

例如下面的代码....

- name: experimenting
  hosts: localhost
  tasks:
  - name: Define some facts
    set_fact:
      people:
      - name: "Fred"
      - name: "John"
      animals:
      - name: "cat"

  - debug:
      msg: "{{ animals | product(people)  }}"  

...产生以下输出：

ok: [localhost] => {
    "msg": [
        [
            {
                "name": "cat"
            },
            {
                "name": "Fred"
            }
        ],
        [
            {
                "name": "cat"
            },
            {
                "name": "John"
            }
        ]
    ]
}

我怎样才能把它变成这样：

ok: [localhost] => {
    "msg": [
        {
            animal: {
                name: "cat"
            },
            person: {
                name: "Fred"
            }
        },
        {
            animal: {
                name: "cat"
            },
            person: {
                name: "John"
            }
        }
    ]
}

在 C# 中，我会使用 LINQ

Select

语句，但我在 ansible 世界中找不到等效的语句。

Chat GPT 3.5 没有帮助，所以我支付了 4.0 升级费用。没过多久就得到了正确答案：

- name: experimenting
  hosts: localhost
  tasks:
  - name: Define some facts
    set_fact:
      people:
      - name: "Fred"
      - name: "John"
      animals:
      - name: "cat"

  - name: Transform the data
    set_fact:
      transformed: "{{ transformed | default([]) + [{'animal': item[0], 'person': item[1] }] }}"
    loop: "{{ animals | product(people) }}"

  - debug:
      msg: "{{ transformed }}"

...产生：

ok: [localhost] => {
    "msg": [
        {
            "animal": {
                "name": "cat"
            },
            "person": {
                "name": "Fred"
            }
        },
        {
            "animal": {
                "name": "cat"
            },
            "person": {
                "name": "John"
            }
        }
    ]
}
