node.js - Mongodb插入空日期

Question

邮件架构:

var mail = new mongoose.Schema({
    globalId: {type: String, index: true, unique: true},
    from: {type: String, required: true},
    beginDate: {type: Date, required: true},
    endDate: {type: Date},
    source: {type: String},
    address: {type: String},
    subject: {type: String, required: true},
    text: {type: String},
    note: {type: String},
    files: [
        {
            fileName: {type: String},
            fileSize: {type: Number},
            fileType: {type: String}
        }
    ]
});

当我尝试保存 endDate 为 null 的新邮件时出现以下错误

Mail validation failed: endDate: Cast to Date failed for value "null"

Answer 1

看起来您正在尝试使用无效的结束日期来保存架构。

如果您不想保存日期，只需将其从对象中删除即可。例如，您至少需要为架构提供的是:

const newMail = mail.create({
    globalId: "1234",
    from: "Jack",
    beginDate: new Date(),
    subject: "Random subject",
});

如果你尝试做类似的事情，

结束日期:null

这将失败，因为它需要一个 Date() 对象或什么都没有。
