javascript - Mongoose 日期字段 - 将默认设置为 date.now + N days

Question

在 Mongoose 模式中，例如:

var EventSchema = new Schema({
	title: {
		type: String,
		default: '',
		trim: true,
		required: 'Title cannot be blank'
	},
	description: {
		type: String,
		default: '',
		trim: true
	},
	start: {
		type: Date,
		default: Date.now,
		required: 'Must have start date - default value is the created date'
	},
	end: {
		type: Date,
		default: Date.now + 7 Days, // Date in one week from now
		required: 'Must have end date - default value is the created date + 1 week'
	},
	tasks: [{
		type: Schema.ObjectId,
		ref: 'Task'
	}]
});

在“结束”字段的行中，默认日期应设置为 +7 天。我可以添加预保存 Hook 并将其设置在那里，但想知道是否有办法在默认字段中内联执行此操作。

Answer 1

default: () => Date.now() + 7*24*60*60*1000

这样就够了
