Re: hasAndBelongsToMany with additional join table columns?
Yeah, I thought about doing that. Would I need to add an id column to that table then, I suppose?

Re: hasAndBelongsToMany with additional join table columns?
Another solution might be (don't know how elegant this is) to add a
finderQuery in your HABTM-relation. Just copy the present habtm-query
(you'll see it with debug level 2, for example), modify it a bit and
add it to your models habtm-statement. In your case the modification
should be something like this: in the SELECT-section add
"posts_tags"."tag_link_id" AS "Tag__tag_link_id" and than modify the
tag_id the JOIN's ON-section to be a magical {$__cakeID__$} and than
your habtm-query should return the tag_link_id in the associated Tag-
model.
As I said, I don't know how elegant this approach is, but it worked
for me :)

Re: hasAndBelongsToMany with additional join table columns?
Try making PostTag a full model for posts_tags, and set hasMany/belongsTo instead of HABTM.

hasAndBelongsToMany with additional join table columns?
Hello all, got a question that I haven't yet seen an answer to... I have a fairly standard many:many relationship, much like the classic Posts-Tags example. I have the standard join table, with an extra column, for example: posts (id, text) tags (id, name) posts_tags (post_id, tag_id, tag_link_id) So this is where it gets unorthodox. Using the standard hasAndBelongsToMany, when I'm iterating a list of posts I can easily enough get the tags. But does anyone have a suggestion for *also* getting the tag_link_id for the association? As an example, I'd like to take a Post, and iterate its array of Tags. For each Tag, I want to get Tag.name but also get the tag_link_id from the corresponding row in posts_tags. I suppose I could do a find in posts_tags using the post_id and tag_id, but that's an extra database query for data that I should already have. Any suggestions of a clever way to carry this associated data along?
