[Nitro] target_singular_name in refers_to.rb

[Rob Pitt]

Heya,

Could anyone tell me where the variable target_singular_name comes from on line 8 in refers_to.rb? It looks like it comes from itself later on in the code but that doesn't make any sense...

The reason I ask is because if you use ObjectGraph in the fashion I described earlier (managing multiple db's where they do not have the same tables and fields on both sites) sometimes this information is missing (and on the other relations too). I think it could be related to situations where Objects are related to other Objects in interconnected ways, I patched 0.23 in horrible ways with things like:

+
     self[:foreign_key] = "#{foreign_name || target_singular_name}_#{target_pk}"

     if self[:field]


But this is horribly hacky and there must be a cleaner way?
