Fix to have acts_as_rateable working with rails 2.1
Edit acts_as_rateable.rb :
Make the dependent option as :nullify instead of :true (has_many :ratings, :as => :rateable, :dependent => :nullify )
Got same problem like Sandeep, help anybody?
Hi,
Do we have Rails 2.1 compatible version of acts_as_rateable? Please let me know how to make it compatible: right now it bails out throwing: ArgumentError (The :dependent option expects either :destroy, :delete_all, or :nullify (true)):
Regards, Sandeep G
Those looking for this kind of functionality but with cached values (like vince) should look at the other plugin acs_as_rated.
Hey, how do we paginate the search on say top rated objects. That rails paginate don't support group option.
this plugin does not scale well. to calculate the ratings, it has to first look up all the ratings for the item, then add them up! if you had to list items by ratings, you would effectively have to do this for each item being rated!! you really need a separate column in the table for the item being rated that gets updated every time it gets rated
There's also similar plugin at http://rubyforge.org/projects/ratable/
