Is there a way to update attributes in a HABTM join table? Right now I am deleting the join and then recreating it with new attributes. I have a table "categories" and another table "items". They are both HABTM with the join table "categories_items" between them. If an item is joined to a category once, no problem, we create the join. But if an item is joined to a category more than once, I want to record the subsequent hit in a field called "cat_count" which exists in the join table. def add_category( category_id_as_str ) category = Category.find(category_id_as_str.to_i) if self.categories.include?(category) old_count = self.categories.find(category.id).cat_count.to_i self.categories.delete(category) else old_count = 0 end self.categories.push_with_attributes(category, :cat_count => old_count + 1) end It seems like there should be a way to update the join instead of deleting and recreating it. I know I could always turn the join into a model--I've done that before but it seems like overkill for something so simple as this. If it knows both unique ids, it should possible. Is there a way to update a HABTM join attribute with a method similar to push_with_attributes? Seems like there should be something like: Object.collection.update_attributes(collection_id, attribute => value) Kevin
