ArangoDB 将每个不同的元素推送到一个数组

Question

所以我在 ArangoDB 中有一个集合，其中子网分配给团队，我想重新格式化该数据，使每个团队一行一行，其中包含一组分配给他们的子网

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",
  }
]

我想将重新格式化的文档插入不同的集合 (Team_to_Subnet)，格式如下：

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？甚至有可能做到吗？我研究过使用 COLLECT，但我就是想不通。

如有任何帮助，我们将不胜感激

Answer 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

ArangoDB 将每个不同的元素推送到一个数组
