Loopback.io找到包含

Question

我在MongoDB中使用Loopback.io。我无法想象如何使用“包含”过滤器。

目标是在完成find（）或findOne（）时将“用户”完全包含在“组”中。我现在得到的是ID中的数组。由于

theuser.json：

{ 
    "name": "theuser", 
    "plural": "theusers", 
    "base": "User", 
    "idInjection": true, 
    "properties": { 
    "peerId": { 
     "type": "string", 
     "required": false 
    }, 
    "peerStatus": { 
     "type": "string", 
     "required": false 
    } 
    }, 
    "validations": [], 
    "relations": { 
    "notes": { 
     "type": "hasMany", 
     "model": "note", 
     "foreignKey": "ownerId" 
    }, 
    "groups": { 
     "type": "hasMany", 
     "model": "group", 
     "foreignKey": "groupId" 
    } 
    }, 

group.json：

{ 
    "name": "group", 
    "plural": "groups", 
    "base": "PersistedModel", 
    "idInjection": true, 
    "properties": { 
    "name": { 
     "type": "string" 
    } 
    }, 
    "validations": [], 
    "relations": { 
    "host": { 
     "type": "belongsTo", 
     "model": "theuser", 
     "foreignKey": "ownerId" 
    }, 
    "clients": { 
     "type": "hasMany", 
     "model": "theuser", 
     "foreignKey": "clientId" 
    } 
    }, 
    "acls": [], 
    "methods": [] 
} 

我试图寻找一组像这样：

Group.findOne({ 
     filter: { 
      where: {"ownerId": 1}, 
      include: {relation: "clients"} 
     } 
} 

Answer 1

Group.findOne({ 
    where: { 
    ownerId: 1 
    }, 
    include: 'clients' 
}, cb);
