How do I append static items to a dict using Jinja2

pkiller162

If I have a list as follows:

[
    {
        "a": "1",
        "b": "2"
    },
    {
        "a": "3",
        "b": "4"
    },
    {
        "a": "5",
        "b": "6"
    }            
]

How can I rename the keys of the first list and append static items to each dict using a Jijja2 filter?

For example:

[
    {
        "a2": "1",
        "b2": "2",
        "c2": "test"
    },
    {
        "a2": "3",
        "b2": "4",
        "c2": "test"
    },
    {
        "a2": "5",
        "b2": "6"
        "c2": "test"
    }            
]

I have attempted something like the following:

{{ my_list | map('json_query', '{a2:a, b2:b}') | list }}

Which is half the battle, but how would I append a static item to the resulting dict?

The following should do:

- debug:
  msg: >-
    {{ my_list | json_query("[].{a2: a, b2: b, c2: 'test' }") }}

Result with a copy paste of your data:

    "msg": [
        {
            "a2": "1",
            "b2": "2",
            "c2": "test"
        },
        {
            "a2": "3",
            "b2": "4",
            "c2": "test"
        },
        {
            "a2": "5",
            "b2": "6",
            "c2": "test"
        }
    ]
}

The order of single and double quotes nesting matters (See jmespath specification). If you put the single/double quotes the other way arround, the result of your static string will be "None"
