I have Kids and I have Sports. I have a checkbox list of Sports for each Kid. Let's say I make a Kid, and assign him to all 5 sports. It works, great. Let's say I make another Kid(Kid2), and assign him to all 5 sports. I get this error: Mysql::Error: Duplicate entry '2' for key 1: INSERT INTO kids_sports (`sport_id`, `kid_id`, `id`) VALUES (2, 10, 2) And my kids_sports table looks like this: id kid_id sport_id Edit Delete 2 8 2 Edit Delete 3 8 3 Edit Delete 4 8 4 Edit Delete 6 8 6 Edit Delete 7 8 7 Why the heck is it doing that? Why isn't id 1,2,3,4,5 etc like it should(?) be?

I think we need to see one your kid/sport model and then the new/ create method in the controller... You should not have a id column btw in the kids_sports table.. . This should be your up task: def self.up create_table :kids_sports, :id => false do |t| t.integer :kid_id t.integer :sport_id end add_index :kids_sports, [:kid_id] add_index :kids_sports, [:sport_id] end On Feb 2, 12:58 pm, Little Known <rails-mailing-l...@andreas-s.net>
