I''m trying to extend the acts_as_taggable plugin (note: not gem) so that
you can specify a list of tags you''re interested in, and the plugin will
return only those items that are tagged with *all* these tags.
The plugin uses primarily two tables: tags, to keep all the various tag

has_and_belongs_to_many dual insert error ?
Hi !
(See references at the end)
I have a slight problem. Whenever I save one of my domain models, which
contains an has_and_belongs_to_many relationship with another one, the
relationships are doubled.
My domain is a series of pictures, where each picture can be tagged with
one or more words. So, a picture of my dog could be tagged "Jordy, Dog,
Dog 2005", for example.
In my
