Error deleting object with has many relationship

Hi,

Im getting this strange error when trying to delete an employee, im
guessing its something to do with one of the has_many relationships but
how do i know which one.

ndefined method `table_name’ for File:Class

vendor/rails/activerecord/lib/active_record/associations/has_many_association.rb:152:in

Random guess: it’s the one called files. That makes rails load up
File, but oh no, it’s found ruby’s File class, which isn’t an
activerecord class and hence doesn’t respond to table_name.
