Actually, it’s probably a generic many_to_many bug.
Problem also exists in trunk.
#!/opt/local/bin/ruby
require ‘og’
require ‘sqlite3’
class Post
attr_accessor :name, String
is Taggable
end
Og.start(
:adapter => ‘sqlite’,
:name => ‘tagtest’,
:destroy_schema => true,
:create_schema => true
)
p=Post.new
p.name = ‘post1’
t1 = Tag.new
t1.name = ‘tag1’
t2 = Tag.new
t2.name = ‘tag2’
p.tags << t1
p.tags << t2
p.save
This exception thrown during save. I expect it’s likely to bring any
blog sample application crashing early. Not a good early impression!
Also of note – notice printed for ogtag and ogpost, but none for
ogj_post_tag. But that’s not important now
