I'm assuming you are meaning you don't want ActiveRecord models. If
thats' the case, then yes it is possible. In fact, I currently do that
in a couple apps that access objects through XML RPC calls. Here is how
I do it, which will give you validations on errors.
class ModelWithoutDatabase
def save() raise NotImplementedError end
def save!() raise NotImplementedError end
def update_attribute() raise NotImplementedError end
def new_record?() true end
include ActiveRecord::Validations
# include ActiveRecord::Errors
def initialize(attributes = nil)
self.attributes = attributes
end
def attributes=(new_attributes)
return unless new_attributes
new_attributes.each do |k, v|
k = "#{k}="
send(k, v) if respond_to?(k)
end
end
def self.human_attribute_name(attribute_key_name) #:nodoc:
attribute_key_name.humanize
end
# Rails 2.2.2 fixes
def self.self_and_descendents_from_active_record; [self]; end
def self.human_name; self.name; end
end
The cool thing about this is that I can still call Model.valid? and use
the validation stuff of ActiveRecord. Then I have my RPC objects that
are Models inherit from the class above so:
class Contact < ModelWithoutDatabase
def method1
rpc calls
end
def method2
rpc calls
end
end
I hope that helps.
