Constructors

Properties

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

    Returns any

  • Parameters

    • value: any
    • model: any
    • options: {} = {}

      Returns any

    • Parameters

      • value: any
      • options: {} = {}

        Returns void

      • Apply a function to this DataField which propagates through recursively to any contained data schema.

        Parameters

        • fn: string | Function

          The function to apply

        • value: any

          The current value of this field

        • Optional options: object = {}

          Additional options passed to the applied function

        Returns object

        The results object

      • 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

      • 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

      • Internal

        Recursively traverse a schema and retrieve a field specification by a given path

        Parameters

        • path: string[]

          The field path as an array of strings

        Returns ObjectField

      • 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

          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

      • Apply an ActiveEffectChange to this field.

        Parameters

        • value: any

          The field's current value.

        • model: DataModel

          The model instance.

        • change: EffectChangeData

          The change to apply.

        Returns any

        The updated value.

      • Internal

        Cast a change delta into an appropriate type to be applied to this field.

        Parameters

        • delta: any

          The change delta.

        Returns any

      • Protected

        Apply any cleaning logic specific to this DataField type.

        Parameters

        • value: any

          The appropriately coerced value.

        • value: any

          The candidate value

        Returns boolean | void

        A boolean to indicate with certainty whether the value is valid. Otherwise, return void.
