ansible/jinja extract multiple attributes from complex json return, rejecting specific matches

I'm trying to extract multiple attributes from a complex payload returned from an API call while rejecting members that have a certain value in the 'name' field. Consider the following payload:

}

}

From this return, I need to store the "name" and "wwn" fields for each volume. Additionally, I need to reject any volume that contains "_os" in the "name" field.

I can get the information using a json_query, but haven't figured out how to reject the volumes with "_os" in their names using this approach.

- name: Set volume name and WWN
  set_fact:
    volume_pairs: "{{ npod_volumes | json_query(volume_query) }}"
  vars: 
    volume_query: "volumes[].{name: name, wwn: wwn}"
  tags: volumes

This gives the following output which includes the unwanted "VMware_Lenovo_server-09.tme.nebulon.com_os" volume.

ok: [127.0.0.1] => {
"volume_pairs": [
    {
        "name": "VMware_Lenovo_VV7",
        "wwn": "6f497c2006187474000ab00000007000"
    },
    {
        "name": "VMware_Lenovo_VV4",
        "wwn": "6f497c2006187474000ab00000004000"
    },
    {
        "name": "VMware_Lenovo_server-09.tme.nebulon.com_os",
        "wwn": "6f497c2006187474000ab00000000000"
    }
]

}

Thanks in advance for your time and consideration!

Vì vậy, tôi đã hạ cánh trên giải pháp này. Sử dụng 'rejectattr', tôi bỏ qua tất cả các tập có chứa "_os" trong tên. Có lẽ có thể được thực hiện theo cách thanh lịch hơn, loại trừ nhu cầu sử dụng truy vấn json của tôi, nhưng nó đã hoàn thành công việc.

  - tên: Lọc ra khối lượng hệ điều hành
    set_fact:
      shared_volumes: "{{ npod_volumes.volumes | 
                        rejectattr('tên', 'chứa', '_os') | 
                        sắp xếp (thuộc tính = 'tên') | danh sách }}"
    đăng ký: kết quả
    thẻ: khối lượng  

  # Thao tác này tạo danh sách các tên tập và WWN của chúng
  - tên: Đặt tên âm lượng và WWN
    set_fact:
      volume_pairs: "{{ shared_volume | json_query(volume_query) }}"
    lọ: 
      volume_query: "[].{name: name, wwn: wwn}"
    thẻ: khối lượng
