Properties

element: DataField

Methods

  • _cast(value: any): any[]
  • _cleanType(value: any, options: any): any
  • _validateType(value: any, options?: {}): void
  • initialize(value: any, model: any): any
  • toObject(value: any): any
  • apply(fn: any, value?: any[], options?: {}): any[]
  • override

    Parameters

    • fn: any
    • value: any[] = []
    • options: {} = {}

      Returns any[]

    • clean(value: any, options: { partial: boolean; source: any }): any
    • 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

      • options: { partial: boolean; source: any }
        • partial: boolean
        • source: any

      Returns any

      The cast value

    • getInitialValue(data: any): any
    • Attempt to retrieve a valid initial value for the DataField.

      throws

      An error if there is no valid initial value defined

      Parameters

      • data: any

        The source data object for which an initial value is required

      Returns any

      A valid initial 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) or by returning false. A validator which returns true denotes that the result is certainly valid and further validations are unnecessary.

      Parameters

      • value: any

        The initial value

      • options: any = {}

      Returns ModelValidationError

      Returns a ModelValidationError if a validation failure occurred

    • _validateElements(value: any[], options: any): any[]
    • Validate every element of the ArrayField

      Parameters

      • value: any[]

        The array to validate

      • options: any

        Validation options

      Returns any[]

      An array of element-specific errors

    • _validateSpecial(value: any): boolean | void
    • 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.

      throws

      May throw a specific error if the value is not valid

      Parameters

      • value: any

        The candidate value

      Returns boolean | void

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

    • _validateElementType(element: any): any
    • Validate the contained element type of the ArrayField

      throws

      An error if the element is not a valid type

      Parameters

      • element: any

        The type of Array element

      Returns any

      The validated element type

    Accessors

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

      Returns string

    • get _defaults(): any
    • inheritdoc

      Returns any
