Thanks, Ryan! Looked into that more yesterday and learned about
ActiveSupport::Dependencies:
https://github.com/rails/rails/blob/3-2-stable/activesupport/lib/active_support/dependencies.rb
It's funny after using Rails so much that I didn't give a lot of thought
how class and module resolution work.
So, I thought I'd try to be crafty and throw together a gem to load in
Rails 3.2 that would do this (among other things):
class Object
class << self
class << self
@ref_classes={}
puts "renaming const_missing to object_const_missing in #{self}"
raise "Not on the right class. this is #{self.class.name}" unless
instance_methods.include?(:const_missing)
alias_method(:object_const_missing, :const_missing)
undef_method(:const_missing)
raise "didn't undefine const_missing on #{self.class.name}" if
instance_methods.include?(:const_missing)
raise "didn't change name of const_missing to object_const_missing
on #{self.class.name}" unless
instance_methods.include?(:object_const_missing)
def const_missing(name)
puts "in my const_missing in #{self}"
return @ref_classes[name] if @ref_classes[name]
if name.to_s.end_with?('Ref')
orig = const_get(name.to_s.chomp('Ref'))
if orig && orig.ancestors.include?(ActiveRecord::Base)
ref = orig.dup
ref.class_eval('include ActiveRecordRefs::Model')
return ref
else
object_const_missing(name)
end
end
end
raise "should have been able to redefine const_missing on
#{self.class.name}" unless instance_methods.include?(:const_missing)
end
end
end
So, that loads but it is completely ignored, and this morning I read
this:
http://wondible.com/2011/12/23/give-rails-autoloading-a-boot-to-the-head/
Getting closer. So my new goal would be to have something that allows
new class "creation" via const_missing that strips off the end and does
something with it, e.g. if an association has class_name:
'Person[RO,attr[first_name,last_name]]' then const_missing would take
that and do a Person.dup and then pass the Person.dup class (named
'Person[RO,attr[:first_name,:last_name]]') off to a user-configurable
class's class method that could do something with it like:
# if the RO token is found would use the be_readonly gem's functionality
new_class.class_eval('include BeReadonly::Now')
# parse out attrs and do
new_class.class_eval("self._accessible_attributes[:default] =
#{attrs.collect{|a|a.to_sym}.inspect}")
It may be too magic, but it would be a way to use associations to have
each model easily define new classes and functionality to tack on to
existing models, and would be a lot more DRY. The reason is because
we're developing another gem that reuses mass assignment security to
define attributes that are serializable to JSON, along with another
custom class_attribute that specifies attributes and associations that
are only serialized.
