Hey All,
I have some associations that seem to be messed up as their methods
(i.e. clear, delete) don''t do anything - no errors, no SQL, nothing!
It''s a polymorphic has_many :through. Here goes:
class Connection < ActiveRecord::Base
belongs_to :idea
belongs_to :connectable, :polymorphic => :true
end
class NewsItem < ActiveRecord::Base
has_many :connections, :as => :connectable, :dependent => :destroy
has_many :ideas, :through => :connections
end
class Idea < ActiveRecord::Base
has_many :connections
has_many :news_items, :through => :connections
end
Let''s say I do this:
>> news_item.ideas << ideas
=> [#<Idea:0x34e5900 @attributes={"name"=>"Test
Idea",
"short_description"=>"Yodel",
"id"=>"10",
"long_description"=>"Homey"}
>, #<Idea:0x34e58b0
@attributes={"name"=>"Hunter''s Other Idea",
"short_description"=>"I had two ideas.",
"id"=>"12",
"long_description"=>"Yes, I did."}>]
>> news_item.ideas.size
=> 2
Great so far. The records are created, everything works. The problem
is that .replace and .clear both do NOTHING:
>> news_item.ideas.clear
=> []
Okay, that looks right but there was no SQL generated for that so...
>> news_item.reload
>> news_item.ideas.size
=> 2
?!?!?! I''ve tried this a million ways and I can''t figure this
out.
Are the relationships specified incorrectly? Like I said, adding
items and viewing them works fine. It''s just anything that requires
the connections between news items and ideas to be deleted that fails
- but there are never any error messages, just a silent failure w/ no
SQL generated.
This is on Rails 1.2.3 / Ruby 1.8.5 on OS X Tiger 10.4.9.
Any help would be very, very much appreciated.
Thanks,
Hunter
