方法创建不会在环回中创建新实例

Question

我正在使用自己的身份验证来开发API。 我创建了一个从User继承的帐户模型，并创建了一个从AccessToken继承的会话模型。

//帐户

  "plural": "accounts",
  "base": "User",
  "idInjection": true,
  "options": {
    "validateUpsert": true

    },
    "name": {
      "type": "string"
    },
    "firstname": {
      "type": "string"
    },
    "lastname": {
      "type": "string"
    },
    "alias": {
      "type": "string"
    },
    "email": {
      "type": "string"
    },

    "sfid": {

      "default": "local"
    }

      }
    }
  },

    {
      "accessType": "*",
      "principalType": "ROLE",

    },
    {

          "description": "",
          "http": {
            "source": "query"
          }
        },
        {
          "arg": "data",
          "type": "any",
          "required": true,
          "description": "",
          "http": {
            "source": "body"
          }
        }
      ],
      "returns": [
        {
          "arg": "token",

          "path": "/signIn",
          "verb": "post"
        }
      ]
    }
  }
}

//会话

{
  "name": "session",
  "plural": "sessions",
  "base": "AccessToken",
  "idInjection": true,
  "options": {
    "validateUpsert": true
  },
  "properties": {
    "sfid": {
      "type": "string"
    },
    "providerId": {
      "type": "string"
    },
    "email": {
      "type": "string"
    },
    "firstName": {
      "type": "string"
    },
    "lastName": {
      "type": "string"
    },
    "ipaddress": {
      "type": "string"
    },
    "provider": {
      "type": "string",
      "default": "local"
    }
  },
  "validations": [],
  "relations": {
    "user": {
      "type": "belongsTo",
      "model": "account",
      "foreignKey": "userId"
    }
  },
  "acls": [
    {
      "accessType": "*",
      "principalType": "ROLE",
      "principalId": "$unauthenticated",
      "permission": "DENY"
    },
    {
      "accessType": "*",
      "principalType": "ROLE",
      "principalId": "$owner",
      "permission": "ALLOW"
    },
    {
      "accessType": "*",
      "principalType": "ROLE",
      "principalId": "Admin",
      "permission": "ALLOW"
    }
  ],
  "methods": {}
}

我在帐户模型中有一个方法登录，它将验证一系列数据，如果它们有效，则需要创建一个令牌并将其返回。 我的问题是，当我使用create方法时，如果会话表中已经存在一条具有相同userId的记录，则会替换它而不是创建它。

    async function storeSession(user) {
        var Session = Account.app.models.session;
        var result = await Session.upsert({
            userId: user.id,
            sfid: user.sfid,
            providerId: user.providerId,
            provider: user.provider,
            firstName: user.firstname,
            lastName: user.lastname,
            email: user.email,
            ipaddress: getIpAddress(),
        });
        return {
            token: result.id,
            user: {
                userId: result.userId,
                sfid: result.sfid,
                providerId: result.providerId,
                provider: result.provider,
                firstName: user.firstname,
                lastName: user.lastname,
                email: result.email,
                ipaddress: result.ipaddress
            }
        }
    };

我希望在会话表中创建一条新记录，但是该方法用一个新ID替换具有相同userId的记录。

谢谢
