My own disliked items in my recommended set

[julianfox]

Hi David,

I found my own disliked items in my recommended set if my similar users like this items, is it normal ?

If yes, it would be a good improvement to delete disliked items by user before to add score in recommended set.

No, items that have been rated by a user should not appear in that user's set of recommendations. Recommendable implements hooks that remove an item from the set of recommendations once it has been rated, and the logic to calculate recommendations also ignores items that have already been rated. Can you please detail your set of actions? This isn't something I've ever been able to make happen.

Why not just report the difference between the recommended items and the
users disliked items?

@hderms Perhaps there's a misunderstanding, but his problem seems to be that a he disliked an item but later found it in his recommendations. Recommendable has hooks that should have removed it from the recommendations, but perhaps they didn't get run for some reason.

Ok, no sorry, after many tests, everything seems ok, error was due to an external code. thanks
