Reference the alias for a join in the index

[Ngan]

Is there a way to reference the alias name for a joined table during the index declaration?

I have an indexes that joins a table twice.  The second one is aliased, and the first is not.  But then I have a:

has "COUNT(DISTINCT(...))", :as => :foo, :type => :integer

But i'm not sure what to put in place of the "..." so that it references the alias name.  I could hardcode it, but that seems fragile...

I'm afraid there's no easy way to do this - so, hardcoding is probably the way to go. It should be reliable enough, though it does depend on the order of statements within your index definition. If you're not changing that code much/at all, then it's fine.

Of course, make sure you add a test in to ensure it's working as you like :)
