如何根据字符串值循环子元素？

Question

我正在使用嵌套字典，并且有多个具有相同键的字典文件。 字典和任务本身正在工作，但我需要添加以下条件。 如果子元素的状态==不存在，则不要运行任务

我的口述：

qualitygate:
  - qualitygate_name: QA-dev
    operators:
      - metric: coverage
        operator: CT
        error: 1
        state: present
  - qualitygate_name: Department-xyc
    operators:
      - metric: coverage
        operator: CT
        error: 10
        state: absent
      - metric: duplicated_lines
        operator: GT
        error: 5
        state: present

使用我的任务：

- ansible.builtin.uri:
    url: "{{ protocol }}://{{ server_fqdn }}/api/qualitygates/create_condition"
    user: "{{ token }}"
    method: POST
    body_format: form-urlencoded
    body:
        error: "{{ item.1.error }}"
        metric: "{{ item.1.metric }}"
        gateName: "{{ item.0.qualitygate_name }}"
        op: "{{ item.1.operator }}"
  loop: "{{ qualitygate | subelements('operators', 'skip_missing=True') }}"
  when: qualitygate[item]['state'] is match("present")

如何更改过滤器以仅匹配值“present”

Answer 1

在条件中使用子元素项

      when: item.1.state == 'present'
