To complete  SamSaffron s answer    You can use class name with either foreign key or inverse of  I personally prefer the more abstract declarative  but it s really just a matter of taste    class BlogPost   has many  images  class name   BlogPostImage   inverse of   blog post   end   and you need to make sure you have the belongs to attribute on the child model   class BlogPostImage   belongs to  blog post end

You could also use alias attribute if you still want to be able to refer to them as tasks as well   class User  lt  ActiveRecord  Base   alias attribute  jobs   tasks    has many  tasks end

You could do this two different ways  One is by using  as   has many  tasks   as   gt   jobs   or  def jobs      self tasks end   Obviously the first one would be the best way to handle it
