Constructors

Properties

element: DataField

The data type of each element in this array

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 = true
recursive: boolean = true

Accessors

  • get model(): typeof Document
  • A reference to the DataModel subclass of the embedded document element

    Returns typeof Document

  • get schema(): SchemaField
  • The DataSchema of the contained Document model.

    Returns SchemaField

  • 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

  • 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

  • Return the embedded document(s) as a Collection.

    Parameters

    • parent: Document

      The parent document.

    Returns DocumentCollection

  • 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.

  • 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

  • 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.

  • Protected

    Special validation rules which supersede regular field validation. This validator screens for certain values which are otherwise incompatible with this field like null or undefined.

    Parameters

    • value: any

      The candidate value

    Returns boolean | void

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

    Throws

    May throw a specific error if the value is not valid

  • Protected

    Render this DataField as an HTML element. Subclasses should implement this method rather than the public toInput method which wraps it.

    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

    Apply a MULTIPLY change to this field.
