字符串数组的Mongoose枚举验证？

Question

是否可以使用enum验证type: [String]？

例:

var permitted = ['1','2','3'];

var exampleSchema = new Schema({
    factors: {
            type: [String],
            enum: permitted,
            required: "Please specify at least one factor."
    }
});

我原以为factors只能包含值permitted.

Answer 1

这对我来说很好(mongoose@4.1.8)

var schema = new mongoose.Schema({
  factors: [{type: String, enum: ['1', '2', '3'], required: ...}] 
  ...
})

注意我正在使用一个对象数组

Answer 2

从mongoose版本5.0.6和更高版本开始，OP 问题现在有效！

 factors: {
            type: [String],
            enum: permitted,
            required: "Please specify at least one factor."
    }
