A simple Rails 3 recommendations engine

coletivo's Issues

Just a quick question

Looks great and seems to work very well.From what I've seen of the code, I'm guessing this uses user-based filtering, and not item based? Correct?

Rails 4 Protected attributes Mass Assigment problem

I have been trying to use this on rails 4 but since rails 4 supports assignment to attributes only which are accessible in their model it's not working
Can you please add rails 4 compatibiity. Need it a bit urgently. Thanks

Mongodb support

I like to use this gem with Mongodb preferably with Mongoid, but not sure about where to start?

It's impossible to get recommendations

Hi,

first of all - THANK YOU very much for this gem and initiative to make easy-to-use recommentadtions engine!

On my test environment (3 users, 7 rankings, all user rated same two items, onw of them rated one more) geting recommendations fails to succeed:

ruby-1.9.2-p290 :007 > Medium.find_recommendations_for(u, :strategy=>:pearson) Coletivo::Models::PersonRating Load (5.1ms) SELECT person_ratings.* FROM person_ratingsWHEREperson_ratings.rateable_type= 'Medium' ArgumentError: wrong number of arguments (1 for 2) from /Users/maciej/.rvm/gems/ruby-1.9.2-p290@rails31/gems/coletivo-0.0.2/lib/coletivo/models/recommendable.rb:60:inblock in predict_highest_ratings'

Any ideas what can go wrong?
