Hi
I have two models Keyword and KeywordResult, they basically look like
this:
class KeywordResult < ActiveRecord::Base
belongs_to :keyword
validates_presence_of :title, :url, :keyword_id
end
class Keyword < ActiveRecord::Base
has_many :keyword_results, :dependent => :delete_all
acts_as_tree :order => “text”, :foreign_key => “top_keyword”
end
Before you ask: I commented all other callbacks and hooks out.
now when I want to add a KeywordResult I get a SystemStackError.
kw = Keyword.find(72)
=> #<Keyword:0x2595ec4 @attributes={“updated_at”=>“2006-07-25
23:50:54”, “text”=>“my keyword”, “lock_version”=>“14”, “id”=>“72”,
“lang”=>“de”, “top_keyword”=>“68”, “created_at”=>“2006-07-25 01:56:48”}>kw.keyword_results
=> []kw.keyword_results << KeywordResult.new({:title => “foobar”, :url =>
“foobar”})
SystemStackError: stack level too deep

I don’t see any loops in my code (all callbacks and other validations
are commented out)
I hope you have some ideas…
Thanks, Tobias
