#value ⇒ Object

── Value access ──

The magic here is that we delegate to the correct typed column based on what the field type declares. ActiveRecord handles all casting through the column’s type (schema-inferred).

So ‘value = “42”` on an integer field writes 42 to integer_value, and `value` reads it back as a Ruby Integer. No custom caster needed for storage - the database column type IS the caster.
