The only way around this problem that I can think of is to use eval: def foo(class_name, conditions) x = eval "#{class_name}.find(:all, :conditions => \"...

...es, how do I do the :belongs_to / :has_many stuff ie. For a given project company A may be writing the spec, but company B may be paying the bill.

Hi all, I''m confused about how I''m supposed to specify a belongs_to relationship when the table includes multiple columns that reference the same parent table. In my case I have a "schedules" table with "opened_by" and "closed_by" columns, that both reference the "users" table. In theory, they can be two different user ids. table
