Error deleting object with has many relationship

Rails
1

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
construct_sql' vendor/rails/activerecord/lib/active_record/associations/has_many_association.rb:6:ininitialize’
vendor/rails/activerecord/lib/active_record/associations.rb:1032:in

transaction' vendor/rails/activerecord/lib/active_record/transactions.rb:104:indestroy’
app/controllers/employees_controller.rb:131:in destroy' -e:4:inload’
-e:4

Anyone got any ideas?

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.
