PATH_CHAR =

Allow-list per RFC 3986 path chars: unreserved + sub-delims + ":" + "@" + "/" plus pct-encoded "%XX". Rejects quotes, backslashes, angle brackets, pipes, braces, control chars, whitespace, "?", and "#" — anything Rails routing would refuse or that would be unsafe to round-trip through a URL.

Instance Method Details

#validate(record) ⇒ Object

Override validate so we can short-circuit before ActiveModel calls record.read_attribute_for_validation, which would crash on records that don't have the redirects attribute.

Two guards, each catching a distinct case:

  1. config + Flipflop — the runtime feature gate. Skips validation when the feature isn't actively in use.
  2. record_supports_redirects? — the structural gate. Catches the case where both feature gates are on but the property wasn't added
