Vex v0.9.2

Vex.ErrorRenderer behaviour (Vex v0.9.2) View Source

Implementation of this behaviour should be set in validator options as :error_renderer or in :vex application config with same key.

Common pattern is to expect :message key in validator options and if it not set use default_message (use get_message function for it).

Result of message function appears in Vex.errors error tuple as last element, for those validators who use Vex.Validator.ErrorMessage (in general they should).
