【问题描述】：

所以我在 ArangoDB 中有一个集合，其中子网被分配给团队，我想重新格式化该数据以使每个团队有一行，其中包含分配的子网数组

集合（Assigment）如下所示：

查询

FOR a IN Assigment
    RETURN a

结果

[
  {
    "assignment_type": "subnet",
    "assigment_crteria": "192.168.1.0/24",
    "team_assignment": "Team1",
    "prime_contact": "John",
  },
  {
    "assignment_type": "subnet",
    "assigment_crteria": "192.168.2.0/24",
    "team_assignment": "Team1",
    "prime_contact": "John",
  },
  {
    "assignment_type": "subnet",
    "assigment_crteria": "192.168.3.0/24",
    "team_assignment": "Team1",
    "prime_contact": "John",
  },
  {
    "assignment_type": "subnet",
    "assigment_crteria": "192.168.4.0/24",
    "team_assignment": "Team2",
    "prime_contact": "Bob",
  },
  {
    "assignment_type": "subnet",
    "assigment_crteria": "192.168.5.0/24",
    "team_assignment": "Team2",
    "prime_contact": "Bob",
  },
  {
    "assignment_type": "subnet",
    "assigment_crteria": "192.168.8.0/24",
    "team_assignment": "Team5",
    "prime_contact": "Anna",
  },
  {
    "assignment_type": "subnet",
    "assigment_crteria": "192.168.9.0/24",
    "team_assignment": "Team2",
    "prime_contact": "Bob",
  },
  {
    "assignment_type": "subnet",
    "assigment_crteria": "192.168.10.0/24",
    "team_assignment": "Team2",
    "prime_contact": "Bob",
  },
  {
    "assignment_type": "subnet",
    "assigment_crteria": "192.168.12.0/24",
    "team_assignment": "Team5",
    "prime_contact": "Anna",
  },
  {
    "assignment_type": "subnet",
    "assigment_crteria": "192.168.13.0/24",
    "team_assignment": "Team1",
    "prime_contact": "John",
  },
  {
    "assignment_type": "subnet",
    "assigment_crteria": "192.168.15.0/24",
    "team_assignment": "Team1",
    "prime_contact": "John",
  },
  {
    "assignment_type": "subnet",
    "assigment_crteria": "192.168.17.0/24",
    "team_assignment": "Team7",
    "prime_contact": "Erick",
  }
]

我想用这种格式将重新格式化的文档插入到不同的集合（Team_to_Subnet）中：

结果

[
  {
    "team": "Team1",
    "cidrs": ["192.168.1.0/24","192.168.2.0/24","192.168.3.0/24","192.168.13.0/24","192.168.15.0/24"],
    "prime_contact": "John"
  },
  {
    "team": "Team2",
    "cidrs": ["192.168.4.0/24","192.168.5.0/24","192.168.9.0/24","192.168.10.0/24"],
    "prime_contact": "Bob"
  },
  {
    "team": "Team5",
    "cidrs": ["192.168.8.0/24","192.168.12.0/24"],
    "prime_contact": "Anna"
  },
  {
    "team": "Team7",
    "cidrs": ["192.168.17.0/24"],
    "prime_contact": "Erick"
  },
]

我该怎么做呢？甚至有可能做到吗？我已经研究过使用 COLLECT，但我就是想不通。

任何帮助将不胜感激

【解决方案1】：

您可以按团队分组并与COLLECT 联系，并使用projection expression 获取属于相应组的子集数组：

FOR a IN Assigment
  COLLECT team = a.team_assignment, prime_contact = a.prime_contact
  INTO cidrs = a.assigment_crteria
  RETURN { team, prime_contact, cidrs }

要保存结果，只需将最后一行替换为：

  INSERT { team, prime_contact, cidrs } INTO Team_to_Subnet

非常感谢，这正是我所需要的。非常感谢。
