OptionsConstructor

OptionsConstructor: SchemaTypeOptions<any, any>

The class that Mongoose uses internally to instantiate this SchemaType's options property.

defaultOptions

defaultOptions: Record<string, any>

Default options for this SchemaType

instance

instance: string

String representation of what type this is, like 'ObjectID' or 'Number'

Optional isRequired

isRequired?: boolean

True if this SchemaType has a required validator. False otherwise.

options

options: AnyObject

The options this SchemaType was instantiated with

path

path: string

The path to this SchemaType in a Schema.

schema

schema: Schema<any, mongoose.Model<any, any, any, any, any, any>, {}, {}, {}, {}, DefaultSchemaOptions, {}, mongoose.Document<unknown, {}, FlatRecord<{}>> & FlatRecord<{}> & Required<{
    _id: unknown;
}>>

            validators

            validators: mongoose.Validator[]

            The validators that Mongoose should run to validate properties at this SchemaType's path.

            Static schemaName

            schemaName: "Buffer"

            This schema type's name, to defend against minifiers that mangle function names.

            Methods

            cast

            • cast(val, doc, init, prev?, options?): any

            • Cast val to this schema type. Each class that inherits from schema type should implement this function.

              Parameters

              • val: any
              • doc: mongoose.Document<any, any, any>
              • init: boolean
              • Optional prev: any
              • Optional options: any

              Returns any

            default

            • default(val): any

            • Sets a default value for this SchemaType.

              Parameters

              • val: any

              Returns any

            get

            • get(fn): this

            • Adds a getter to this schematype.

              Parameters

              • fn: Function

              Returns this

            immutable

            • immutable(bool): this

            • Defines this path as immutable. Mongoose prevents you from changing immutable paths unless the parent document has isNew: true.

              Parameters

              • bool: boolean

              Returns this

            index

            • index(options): this

            • Declares the index options for this schematype.

              Parameters

              • options: any

              Returns this

            ref

            • ref(ref): this

            • Set the model that this path refers to. This is the option that populate looks at to determine the foreign collection it should query.

              Parameters

              • ref: string | boolean | mongoose.Model<any, {}, {}, {}, any, any>

              Returns this

            required

            • required(required, message?): this

            • Adds a required validator to this SchemaType. The validator gets added to the front of this SchemaType's validators array using unshift().

              Parameters

              • required: boolean
              • Optional message: string

              Returns this
