# Ansible filter: get_attr

This filter overcomes Ansible's lack of variable substitution within dict keys.

* Issue: https://github.com/ansible/ansible/issues/17324

## Usage

```yaml

# Just to set some variables

- set_fact:

    key1: "Name"

    val1: "my-name"

    key2: "tier"

    val2: "dev"

# Here we actually use variables

- set_fact:

    key_val:

      - key: "{{ key1 }}"

        val: "{{ val1 }}"

      - key: "{{ key2 }}"

        val: "{{ val2 }}"

# The filter will actually reorder the above array into a dictionary.

- debug:

    msg: "{{ key_val | get_attr('key', 'val') }}"

```

This will result in the following output:

```json

{

  "key_val": {

    "Name": "my-name",

    "tier": "dev"

  }

}

```

## Integration

Copy `get_attr.py` into your roles `filter_plugins/` directory.
