add

v3.1.0 - Show latest stable - Class: ActiveModel::Errors

add(attribute, message = nil, options = {})

public

Adds message to the error messages on attribute, which will be returned on a call to on(attribute) for the same attribute. More than one error can be added to the same attribute in which case an array will be returned on a call to on(attribute). If no message is supplied, :invalid is assumed.

If message is a symbol, it will be translated using the appropriate scope (see translate_error). If message is a proc, it will be called, allowing for things like Time.now to be used within an error.

# File activemodel/lib/active_model/errors.rb, line 212
    def add(attribute, message = nil, options = {})
      message ||= :invalid

      if message.is_a?(Symbol)
        message = generate_message(attribute, message, options.except(*CALLBACKS_OPTIONS))
      elsif message.is_a?(Proc)
        message = message.call
      end

      self[attribute] << message
    end

Actually, use model_instance.errors.add :base, :invalid to have I18n working.
