Class: TypedEAV::Field::MultiSelect

Inherits:

Includes:
Optionable
Defined in:
app/models/typed_eav/field/multi_select.rb

Overview

Multi-choice option-set field. Stores the chosen values as a JSON array in ‘json_value`. Inherits `optionable? = true`, the public-facing sorted `allowed_values` helper, and the protected `validate_multi_option_inclusion` helper from `Field::Optionable`. Stays a direct child of `Field::Base` — Optionable is a concern (mixin), not an intermediate STI class, because Select and MultiSelect don’t share a ‘value_column`.

‘validate_array_size` is called directly from `Field::Base` (cross-family outlier; also used by `Field::IntegerArray`).
