Been looking for an opportunity to help out for a little while, and I just noticed that there was one reference in CollectionAssociation's class docs to AssocationCollection. I also noticed that it was referenced (in a string) in the NamedScopeTest.
Also, should the header # = Active Record Association Collection be changed to # = Active Record Collection Association?
# = Active Record Association Collection
# = Active Record Collection Association
Modified CollectionAssociation to refer to the new class name.
Modified NamedScopeTest to use CollectionAssociation.
I think it is fine to change the header as well. No big deal, but looks good to be consistent with the class name. You could revise that bit through docrails directly.
Cool stuff. Thanks guys!
