Overview

Converts attribute paths between different formats.

EasyTalk uses dot notation for nested model errors (e.g., "email.address"). This class converts those paths to different standard formats:

  • JSON Pointer (RFC 6901): /properties/email/properties/address
  • JSON:API: /data/attributes/email/address
  • Flat: email.address (unchanged)

Examples:

PathConverter.to_json_pointer("email.address")
# => "/properties/email/properties/address"

PathConverter.to_jsonapi_pointer("email.address")
# => "/data/attributes/email/address"
