How to Create and Use Enum in Mongoose

I am trying to create and use an enum type in Mongoose. I checked it out, but I'm not getting the proper result. I'm using enum in my program as follows:

My schema is:

var RequirementSchema = new mongooseSchema({
   status: {
        type: String,
        enum : ['NEW','STATUS'],
        default: 'NEW'
    },
})

But I am little bit confused here, how can I put the value of an enum like in Java NEW("new"). How can I save an enum in to the database according to it's enumerable values. I am using it in express node.js.

Thanks

Solution 1:

The enums here are basically String objects. Change the enum line to enum: ['NEW', 'STATUS'] instead. You have a typo there with your quotation marks.

Solution 2:

From the docs

Mongoose has several inbuilt validators. Strings have enum as one of the validators. So enum creates a validator and checks if the value is given in an array. E.g:

var userSchema = new mongooseSchema({
   userType: {
        type: String,
        enum : ['user','admin'],
        default: 'user'
    },
})

Solution 3:

Let say we have a enum Role defined by

export enum Role {
  ADMIN = 'ADMIN',
  USER = 'USER'
}

We can use it as type like:

{
    type: String,
    enum: Role,
    default: Role.USER,
}

Solution 4:

If you would like to use TypeScript enum you can use it in interface IUserSchema but in Schema you have to use array (Object.values(userRole)).

enum userRole {
    admin = 'admin',
    user = 'user'
}

interface IUserSchema extends Document {
    userType: userRole
}

const UserSchema: Schema = new Schema({
    userType: {
        type: String,
        enum: Object.values(userRole),
        default: userRole.user, 
        required: true
    }
});
