composed_of freezes objects but if my object requires validations ie
class MyObject
validate do |record|
if fail?
record.errors.add :base, “FAIL!”
end
end
end
class Foo < ActiveRecord::Base
composed_of :my_object,
:allow_nil => true,
:mapping => [
%w[bgmd_name name],
%w[bgmd_serial_number serial_number]
]
validates_associated :my_object
end
this borks with a object is frozen error deep in lib/active_model/validations.rb
I’ve got a work around
module MySugr
This module is mainly a hack to get around a bug with composed_of freezing objects
and ActiveRecord::Validations requiring unfrozen objects
module Composable
def self.included(base)
base.send :extend, ClassMethods
base.send :include, ActiveRecord::Validations
base.send :include, InstanceMethods
base.send :define_method, :“validation_context=” do |*args|
end
end
module InstanceMethods
def initialize(*args)
errors
end
def new_record?
true
end
end
module ClassMethods
end
end
end
which I can mix into my class but it is not ideal. How to report a rails bug? The lighthouse
tracker seems invite only these days?

And I’m using Rails 3.1 RC1!

Rails moved to using github issues recently.
I believe validates_associated with was intended to be used with
associations rather than aggregations. You might find validates_with
useful
Fred
validates_with is not really the solution. Aggregations are semantically the same as has_one relations and should be able to validate
the same as.
Looks like somebody closed the issue on github after importing from lighthouse without solving the issue
https://github.com/rails/rails/issues/727
or explaining why it will not be solved.
Not sure I agree.
All the imported issues were closed automatically at some point - it
wasn't a reflection on the merit of those issues
Fred
I guess I’ll open it up again then
