Short answer: Use set_table_name <http://api.rubyonrails.org/classes/ActiveRecord/Base.html#method-c-set_table_name> in Post. [Though I haven't tried this and there may be further complications.] Long answer: You're almost certainly doing the wrong thing. If you want to share code between non-similar models, don't do it using inheritance. Create a module which encapsulates the functionality (people tend to put such stuff in the lib/ directory), and include the module in the models instead. If it might be useful for several different projects, you could put your module in a plugin, and then have the module automatically include itself in ActiveRecord::Base (therefore making its behaviour available to all models).
