Mongoose enum Validation on String Arrays?

Is it possible to use enum validation on type: [String]?

Example:

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

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

I would have expected that factors would only be able to contain the values in permitted.

Mongoose before version 4.0 didn't support validation on Schema static methods like .update, .findByIdAndUpdate, .findOneAndUpdate.

But it supports on instance method document.save().

So, either use document.save() for inbuilt initiating validation or this { runValidators: true } with methods like .update, .findByIdAndUpdate, .findOneAndUpdate.

reference: Mongoose .update() does not trigger validation checking

you can use something like this

{
 factors: [
    {
      type: [String],
      enum: ['1', '2', '3'],
    },
  ],
}

if you have enuns or you have object enuns

brand: {
    type: String,
    required: true,
    enum: Object.values(TypeBrandEnum)
  },

TRY THIS

let inventory_type_enum = ["goods", "services"];

 inventory_type: {
    type: String,
    enum: inventory_type_enum,
    validate: {
      //  validator: (inventory_type) => !inventory_type.enum.includes(inventory_type),
        validator: (inventory_type) => inventory_type_enum.includes(inventory_type),
        message: languages('general_merchandise_model','inventory_type')
    },
      required : [true, languages('general_merchandise_model','inventory_type_required')],
},

As of mongoose version 5.0.6 and higher, the OP issue now works!

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

This is working fine for me ([email protected])

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

Note I'm using an Array of Objects
