In Hobo has_one :through thinks it's an Array
Reported by Betelgeuse | December 20th, 2010 @ 05:09 PM | in Hobo 1.0X
Given associations:
belongs_to :parent
has_one :parent_parent, :through => :parent
In this case we get:
>> t.parent_parent.class
=> ParentParent
>> t.parent_parent.is_a?(Array)
=> true
Faulty code found via debugger:
[31, 40] in /usr/local/lib/ruby/gems/1.8/gems/hobo-1.0.2/lib/active_record/association_collection.rb
31 proxy_respond_to?(args) || Array.new.respond_to?(args)
32 end
33
34 # TODO: send this patch into Rails. There's no reason to load the collection just to find out it acts like an array.
35 def is_a?(klass)
=> 36 [].is_a?(klass)
37 end
38
39 def member_class
40 proxy_reflection.klass

Interstingly, it appears that this problem occurs on Rails 2.3.10 but not on 2.3.5. EDIT: oops, ignore this comment, it was something else. The problem is more universal.

I did add a test to hte2/hobo-test for this condition. I know it's more work to port hte2 or hobo-test to Rails3 than to try this scenario on your own, but it would kill more birds with one stone. :)
