Question

所以，我被困在一个问题上，这应该很简单，而且我确信我错过了一些明显的东西

我正在关注此文档：

所以我有3张桌子

客户，团队，客户团队

client.json

{
  "name": "client",
  "base": "PersistedModel",
  "idInjection": true,
  "options": {
    "validateUpsert": true
  },
  "properties": {
    "name": {
      "type": "string",
      "required": true
    }
  },
  "validations": [],
  "relations": {
    "teams": {
      "type": "hasMany",
      "model": "team",
      "foreignKey": "teamId",
      "through": "client-team"
    }
  },
  "acls": [],
  "methods": {}
}

team.json

{
  "name": "team",
  "base": "PersistedModel",
  "idInjection": true,
  "options": {
    "validateUpsert": true
  },
  "properties": {
    "type": {
      "type": "string",
      "required": true,
      "default": "first-team"
    },
    "name": {
      "type": "string",
      "required": true
    }
  },
  "validations": [],
  "relations": {
    "clients": {
      "type": "hasMany",
      "model": "client",
      "foreignKey": "clientId",
      "through": "client-team"
    }
  },
  "acls": [],
  "methods": {}
}

客户team.json

{
  "name": "client-team",
  "base": "PersistedModel",
  "idInjection": true,
  "options": {
    "validateUpsert": true
  },
  "properties": {
    "clientId": {
      "type": "string",
      "required": true
    },
    "teamId": {
      "type": "string",
      "required": true
    }
  },
  "validations": [],
  "relations": {
    "client": {
      "type": "belongsTo",
      "model": "Client",
      "foreignKey": "clientId"
    },
    "team": {
      "type": "belongsTo",
      "model": "Team",
      "foreignKey": "teamId"
    }
  },
  "acls": [],
  "methods": {}
}

因此所有关系设置正确（我认为）......

然后在我的客户中我有1个客户

[
  {
    "name": "Client name",
    "id": "59876185508eb519385779c6"
  }
]

在我的团队中我有很多，但肯定是这样的：

[
  {
    "type": "type",
    "name": "Team name",
    "id": "5ae8a37add2989a32d37f83d"
  }
]

然后我去了我的

本地主机：3000 /资源管理器

发布客户团队

像这样

{
    "clientId": "59876185508eb519385779c6",
    "teamId": "5ae8a37add2989a32d37f83d"
}

我得到200回复：

{
  "clientId": "59876185508eb519385779c6",
  "teamId": "5ae8a37add2989a32d37f83d",
  "id": "5ae961873a7e3b33f0579fc3"
}

所以连接就在那里......

但是，当我去“GET client / id”并做

时

id：59876185508eb519385779c6 过滤器：{“include”：[“团队”]}

这是回复

{
  "name": "Chelsea FC",
  "id": "59876185508eb519385779c6",
  "teams": []
}

同样的情况发生在“GET队/身份证”中，我使用

id：5ae8a37add2989a32d37f83d 过滤器：{“include”：[“clients”]}

或者如果我去“获取团队/ {id} / clients” 并把 id：5ae8a37add2989a32d37f83d

我得到了

[]

那么我做错了什么？我确信我错过了一个愚蠢而明显的事情：/

使用mongo如果有任何区别

Answer 1

这里有三个问题：

您将mongodb标识符描述为字符串，这就是您将字符串存储在数据库而不是对象ID中的原因。（它不是必需的，因为数据源应该理解真实的类型）
您的模型从小写字母开始。关系也应该如此。（问题的第一部分，它解决了ids的问题）
客户端和团队模型的关系不正确（问题的第二部分，它的修复包括在内）

客户team.json

  "name": "client-team",

      "type": "objectId", // !!! changed (not required)

      "model": "team",
      "foreignKey": "clientId", // !!! changed (we describing id of this model, not team)
      "through": "client-team"
    }
  },
  "acls": [],
  "methods": {}
}

team.json

{
  "name": "team",
  "base": "PersistedModel",
  "idInjection": true,
  "options": {
    "validateUpsert": true
  },
  "properties": {
    "type": {

      "required": true,
      "default": "first-team"
    },
    "name": {
      "type": "string",
      "required": true
    }
  },
  "validations": [],
  "relations": {
    "clients": {
      "type": "hasMany",
      "model": "client",
      "foreignKey": "teamId", // !!! changed (the same as the previous)
      "through": "client-team"
    }
  },
  "acls": [],
  "methods": {}
}
