I created a data aggregation using the activerecord composed_of method.
It worked fine with rails 1.2.3 but after I recently upgraded to rails
2.0.2 I get the following error when I try to access it:
NoMethodError: undefined method `constantize'' for
EventDescription:Class
from C:/Program
Files/ruby/lib/ruby/gems/1.8/gems/activerecord-2.0.2/lib/active_record/aggregations.rb:156:in
`description''
from (irb):2
Has anyone else encountered this problem?

Show us the whole backtrace please. I think there''s something else going on at work here. I''m also interested in how you got that error as it seems like you''re calling a string method (constantize) on a class.

Attached is the complete stack trace and the aggregate class and model code. Thanks Ryan Bigg wrote:> Show us the whole backtrace please. I think there''s something else going > on > at work here.

Thanks Your suggestion proved correct. I was not enclosing the class name in quotes in the class name option of the composed_of method. I do believe I was not enclosing the class name in quotes in version 1.2.3 and was able to get away with it.
