Hi, I'm trying to sum up the records in a related table that used to just be a child table. This line used to work:
table1.sum(:enrich_bead_count_hemo, :conditions => "table2_id = " + id.to_s) now I've got an intermediate "has and belongs to many" = HABTM table inbetween them. Could somebody help me figure out how to sum across two tables? I'm thinking i might have to use the custom SQL "join" attribute of the sum method.
