Mongoose Schema 中带有日期的 CastError

Question

我有一个包含日期的架构：

const dateSchema = new mongoose.Schema({
  resortName: {
    type: String,
    required: true,
  },
  date: {
    type: Date,
    required: true,
  },
  runName: {
    type: String,
    required: true,
  },
  weatherConditions: String,
  windConditions: String,
  snowConditions: String,
  runTime: Number,
  runCrowded: Boolean,
  runJumps: Boolean,
  runNotes: String,
});

并且我正在为我的数据库播种一些虚拟 JSON:

[{
    "resortName": "Winter Park",
    "date": "2022-04-15T09:31:03.503Z",
    "runName": "Mary Jane",
    "runDifficulty": "blue",
    "weatherConditions": "cloudy",
    "windConditions": "windy",
    "snowConditions": "icy",
    "runTime": 13,
    "runCrowded": true,
    "runJumps": false,
    "runNotes": "Crowded run, patches of ice in middle of slope"
}]

我创建了以下路线：

dateRouter.get("/", (req, res) => {
  Date.find({}).then((dates) => {
    res.json(dates);
  });
});

，但是当我尝试访问路线时出现以下错误：

首先我认为您有命名冲突，Date 是 javascript/node 中的保留字，如果您更改集合名称，问题应该会自行解决

但您可能对以下内容有更好的体验：


dateRouter.get("/", async (req, res) => {
  // (change Date to a different name)
  const records = await Date.find({})
  res.json(records)
})

Mongoose Schema 中带有日期的 CastError
