Type validation

You can define a type for a schema property passing a "type" parameter to it.

new Schema({ name: { type: String }})

Valid types are

• String

• Number (an integer or a gcloud.datastore.int)

• Array

• Object

• Boolean

• Date(*)

• Buffer

• Schema.Types.Double (a float or a gcloud.datastore.double)

• Schema.Types.GeoPoint (a gcloud.datastore.geoPoint)

• Schema.Types.Key (an entity Key)

(*) Valid datetime are javascript Date() or a string with the following format: 'YYYY-MM-DD' | 'YYYY-MM-DD 00:00:00' | 'YYYY-MM-DD 00:00:00.000' | 'YYYY-MM-DDT00:00:00'

So back to our previous example of a User Model, we would probably have something like this.

const userSchema = new Schema({
    name: { type: String },
    lastname: { type: String },
    password: { type: String },
    email: { type: String },
    company: { type: Schema.Types.Key, ref: 'Company' },
    votes: { type: Number },
    dateOfBirth: { type: Date },
    createdOn: { type: Date },
    modifiedOn: { type: Date }
});

Note: you are not forced to set a type, if you don't define one, then any type is valid.

const userSchema = new Schema({
    name: {}, // any type
    email: { type: String }
});
