问题描述
在mongoose模式中,例如:
In a mongoose schema such as:
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' }] });
在结束字段的行上,默认日期应设置为+7天。我可以添加预设钩子并将其设置在那里,但想知道是否有一种方法可以在默认字段中内联。
On the line for the "end" field the default date should set to +7 days. I can add presave hook and set it there, but wondering if theres a way to do this inline in the default field.
推荐答案您可以将7天转换为毫秒转换为当前日期,如此
You can add 7 days converted to milliseconds to current date like this
default: new Date(+new Date() + 7*24*60*60*1000)甚至喜欢这个
default: +new Date() + 7*24*60*60*1000更多推荐
