I would suggest first splitting the statement into several lines performing a single operation on each line, this will enable you to identify which part of the statement is generating the error. Also try playing in ruby console to try and see what is going on. Finally you could use ruby-debug to break in to the code and examine the types of the variables to find what may not be quite as you expect. Also you did not answer the question as to whether this is in a migration. If so then it fraught with problems, it is not advisable to seed data within a migration if that is what you are doing.
