Recommendations and acl
Hey,
We build a social network where people join spaces. In the spaces, there is
content : discussions, documents etc....
The recommender is quite similar to the one described in the books or
tutorial. But how can we manage the ACL ?
The recommender can only give recommendations* people are allowed to see.*
I was thinking about using an IDrescorer to check the ACL for each
recommendation but it seems expensive in terms of perfomances.
Does anyone work with that kind of thing ?
Thanks. Bye
Alex

Thanks for this quick answer. I'll look into it.

You can implement a custom CandidateItemsStrategy. This component is
responsible for selecting candidate items to recommend (the pool from
which to pick the recommended items afterwards). So if you compute
recommendations for a particular person, you need to ensure that your
CandidateItemsStrategy only picks the spaces this person would be
allowed to enter.
