[NoSQL / MongoDB中的1：1和群聊模式

Question

我想为1：1和群组聊天活动创建聊天应用程序。

我已经为两种情况创建了一个架构：

{ // group 
    "id": 1 // id of the group
    "name": "Chat Group" // name of group; if there are more than 2 members
    "members": [ "member1", "member2", ...] // ids of the group chat members; only they have access to the JSON document
    "chatlog": [ "timestamp1": ["member1", "message1"], "timestamp2": ["member2", "message2"], ...] // who sent which message in chronological order
}

将用户的访问列表存储在如上所示的“成员”数组中会更好，还是"chat_groups"的解决方案更好：

{ // user 
    "id": 1 // id of the user
    "name": "Max" // name of the user
    "chat_groups": [ "1", "2", ...] // ids of the groups, the user is a member of
}

Answer 1

根据this帖子，应该有3个节点，user，convo和messages。 convo决定是1：1聊天还是群聊。另外，您可以在creator中添加另一个属性作为convo来设置组管理员权限。

示例：用户

{ // user
  "id": 123,
  "name": "Omkar Todkar"
}

示例： Convo

{ // group
  "id": 1,
  "members": [123, 234, 345]
  "creator": 123
},
{ // 1:1
  "id": 2,
  "members": [123, 345]
  "creator": 123
}

示例：消息

{ // group message
  "convo_id: 1,
  "author": 123,
  "content": "Welcome, to our new group."
},
{ // 1:1 message
  "convo_id: 2,
  "author": 123,
  "content": "Hey, you wanna join us in group?."
},
{ // 1:1 message
  "convo_id: 2,
  "author": 345,
  "content": "Sure, I would love to join."
},
{ // group chat
  "convo_id: 1,
  "author": 234,
  "content": "Hi, Happy to see you both here."
}
