Hi Anjos,
Which is the class that is not ActiveRecord descendent ? Im
assuming Taxes::Premisefinder
define an errors class this way
class Error
attr_accessor :errors
def initialize
@errors = {}
end
def add(key, message)
self.errors[key] = message
end
end
class Car
def errors
@errors ||= Error.new
end
end
@car = Car.new
@car.errors.add(:name, "Invalid")
And you can define valid? method and add errors accordingly.
Its not perfect but can be a good starting point.
