So, I'm posting a reply to my own original post. I fixed my problem and
thought I'd follow up for posterity.
The pertinent broken code was:
def self.included(base)
base.send :extend, ClassMethods
base.send :include, InstanceMethods
base.send :alias_method_chain, :belongs_to, :polymorphism
end
The fixed code is:
def self.included(base)
base.send :extend, ClassMethods
base.send :include, InstanceMethods
class << base
alias_method_chain :belongs_to, :polymorphism
end
end
Calling alias_method_chain (or just alias_method for that matter) on the
class from "outside" (aka by klass.send :alias_method, ...) runs in the
wrong context. It wants to alias regular instance methods of the klass.
Instead, alias_method needs to happen in (still don't know proper ruby
terms for this stuff, sorry) *class* scope (???) so that it will look
for class methods to alias.
As an aside, I was quite retarded when, in my previous post, I ran the
following command in an attempt to see if the belongs_to method was in
fact defined:
ActiveRecord::Base.methods.find {|m| m =~ /belongs_to/}
If, of course, instead finds the first method that matches which was
`has_and_[i]belongs_to[/i]_many' in my case. I should've been using
[i]find_all[/i] instead. Well, yeah, just an FYI.
