pico_phone-rails wires the pico_phone gem into Rails: a :phone_number ActiveRecord attribute type, a PhoneValidator for ActiveModel validations, a normalize_phone class macro that rewrites phone attributes to E.164 before validation, extract_phone_numbers_from for pulling phone numbers out of free text (with an optional persisted backend for cross-record search), maintain_phone_search_index for keeping search columns in sync on an existing phone-number table, and an ActiveJob serializer so a PhoneNumber survives being passed as a job argument.
