Question

我有这样的字典

customers:
  abc:
    id: 1
    status: active
  def:
    id: 2
    status: inactive
  ghi:
    id: 3
    status: active
  jkl:
    id: 4
    status: active

构建像以下活跃客户的字符串的最佳方法是什么？

abc,ghi,jkl

Answer 1

例如：

---
- hosts: localhost
  gather_facts: no
  vars:
    customers:
      abc:
        id: 1
        status: active
      def:
        id: 2
        status: inactive
      ghi:
        id: 3
        status: active
      jkl:
        id: 4
        status: active
  tasks:
    - debug:
        msg: "{{ customers | dictsort | selectattr('1.status','equalto','active') | map(attribute='0') | join(',') }}"

Answer 2

并非完全符合您的要求，但我认为这可能会增加问题的价值。

就我而言，我需要使用空格将项目列表连接起来。

backup_dev_strip:
  - "@stripped"
  - "@development"

结果

---
backup_dev_strip_merged: "{{ backup_dev_strip | join(' ') }}"
