Overview

This class is abstract.

Subclass and override #determine_value to customize value extraction from models

Base class for all field components.

AbstractField provides common functionality shared by all form fields including:

  • Automatic label and placeholder resolution from I18n

  • Model property binding with ‘prop` parameter

  • Client-side validation with automatic error messages

  • Form integration and dirty checking

  • Change event handlers

Note:

Supported validation types: presence, required, absence, acceptance, numericality, format, inclusion, exclusion, length

Validates field input according to specified rules.

Examples:

validation presence: { message: 'Required' }
validation format: { with: /\A\d+\z/, message: 'Must be a number' }
validation length: { minimum: 3, maximum: 20, message: { too_short: 'Too short', too_long: 'Too long' } }

Parameters:

  • validation (Hash) —

    Hash of validation types and their options
