loopbackjs - 环回模型 CURRENT_TIMESTAMP

Question

我有一个这样的模型 -

{
  "name": "MakeCallTestConfiguration",
  "base": "PersistedModel",
  "idInjection": true,
  "properties": {
    "id": {
      "type": "number",
      "id": true,
      "generated": true
    },
    "destination": {
      "type": "string",
      "required": true
    },
    "clientId": {
      "type": "number",
      "required": true
    },
    "logTime":{
      "type" : "date",
    }
  },
  "validations": [],
  "relations": {},
  "acls": [],
  "methods": []
}

对于“logTime”，如何自动生成时间戳？我的意思是像

“TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP”

Answer 1

您可以使用“$now”属性

"logTime":{
  "type": "date",
  "required": true,
  "default": "$now"
}
