vote_fu to work in Heroku (Postgres)

December 6, 2009 at 3:19 pm Leave a comment

In order to make vote_fu work in Heroku’s PostgreSQL you need to make a slight modification in the tally method, to follow a classical SQL notation:

Add this method in acts_as_voteable.rb just after options_for_tally method:

	def column_names_for_tally { |column| "#{table_name}.#{column}" }.join(", ")

In options_for_tally method find line that starts with “group_by =” and replace it with:

group_by  = "#{Vote.table_name}.voteable_id, #{column_names_for_tally}"

That’s it. Should work now.
