types: {
    [type: string]: SchemaField;
}

The types of this field.

Type declaration

name: string

The field name of this DataField instance. This is assigned by SchemaField#initialize.

parent: DataField

A reference to the parent schema to which this DataField belongs. This is assigned by SchemaField#initialize.

The initially provided options which configure the data field

hierarchical: boolean = false

Whether this field defines part of a Document/Embedded Document hierarchy.

recursive: boolean = false

Does this field type contain other fields in a recursive structure? Examples of recursive fields are SchemaField, ArrayField, or TypeDataField Examples of non-recursive fields are StringField, NumberField, or ObjectField

Accessors

  • get fieldPath(): string
  • A dot-separated string representation of the field path within the parent schema.

    Returns string

  • get _defaults(): object
  • Default parameters for this field type

    Returns object

  • get hasFormSupport(): boolean
  • Does this form field class have defined form support?

    Returns boolean

Methods

  • Parameters

    • value: any
    • options: any

    Returns any

  • Parameters

    • value: any

    Returns any

  • Parameters

    • value: any
    • model: any
    • options: any

    Returns any

  • Parameters

    • fn: any
    • data: any
    • options: any

    Returns {}

    • Migrate this field's candidate source data.

      Parameters

      • sourceData: object

        Candidate source data of the root model

      • fieldData: any

        The value of this field within the source data

      Returns void

    • Coerce source data to ensure that it conforms to the correct data type for the field. Data coercion operations should be simple and synchronous as these are applied whenever a DataModel is constructed. For one-off cleaning of user-provided input the sanitize method should be used.

      Parameters

      • value: any

        The initial value

      • Optional options: {
            partial: boolean;
            source: object;
        } = {}

        Additional options for how the field is cleaned

        • partial: boolean

          Whether to perform partial cleaning?

        • source: object

          The root data model being cleaned

      Returns any

      The cast value

    • Attempt to retrieve a valid initial value for the DataField.

      Parameters

      • data: object

        The source data object for which an initial value is required

      Returns any

      A valid initial value

      Throws

      An error if there is no valid initial value defined

    • Validate a candidate input for this field, ensuring it meets the field requirements. A validation failure can be provided as a raised Error (with a string message), by returning false, or by returning a DataModelValidationFailure instance. A validator which returns true denotes that the result is certainly valid and further validations are unnecessary.

      Parameters

      Returns DataModelValidationFailure

      Returns a DataModelValidationFailure if a validation failure occurred.

    • Internal

      Certain fields may declare joint data validation criteria. This method will only be called if the field is designated as recursive.

      Parameters

      • data: object

        Candidate data for joint model validation

      • options: object = {}

        Options which modify joint model validation

      Returns void

      Throws

      An error if joint model validation fails

    • Render this DataField as an HTML element.

      Parameters

      • config: FormInputConfig = {}

        Form element configuration parameters

      Returns HTMLElement | HTMLCollection

      A rendered HTMLElement for the field

      Throws

      An Error if this DataField subclass does not support input rendering

    • Render this DataField as a standardized form-group element.

      Parameters

      • groupConfig: FormGroupConfig = {}

        Configuration options passed to the wrapping form-group

      • inputConfig: FormInputConfig = {}

        Input element configuration options passed to DataField#toInput

      Returns HTMLDivElement

      The rendered form group element
