Hi,

I have a one sided has_and_belongs_to_many example similar to this:

class Post
has_and_belongs_to_many :tags, inverse_of: nil, index: true
end

class Tag

1. you don't want this side to have post_ids since it could be 1000s of posts
   end

I would still like to have the accessor methods on the Tag side. I started writing my own like this:

def posts
Posts.where(tag_ids: self.id)
end

def posts<< ps
Post.collection.update(
Post.any_in(_id: ps.collect

{|p| p.id }).selector,
{'$push' => {tag_ids: self.id}},
{:multi => true}
)
end

def posts= ps
Post.collection.update(
Post.any_in(_id: ps.collect{|p| p.id }

).selector,
{'$set' => {tag_ids: self.id}},
{:multi => true}
)
end

But i realized there are a lot...plus callbacks for when a post is destroyed etc. So I thought maybe there was an easier way? For example maybe if I could just override the selector the rest would work normally.

Thanks for any ideas!
