In order to implement inheritance (STI was not ideal), I have implemented a solution similar to what is described in this post: Any good alternative to single-table-inheritance? - Rails - Ruby-Forum. I have one model that acts as a parent class with shared attributes, two child models with different attributes, and a module that contains shared functionality for the child models.
The issue arises in creating associations with other models when it is necessary to provide conditions on the association, for example:
has_many :foos, :conditions => "foo_metadata.created_at < #{Time.now}", :order => 'foo.bar DESC, foo_metadata.baz'
I can use eager loading to include the foo_metadata relationship, however, this becomes cumbersome and difficult to manage throughout the application. Is there an alternative solution to this problem? Would composed_of (or other composition options) be of any help?
Thanks, Josh
