Ruby ActiveRecord Basics Migrations and Relationships Single Table Inheritance

Posted by Wesley Wright

So... I think I missed a step, messed something up, or something...

I now no longer have a customers table in my database, but I do still have an empty employees table (think I misspelled 'drop', but maybe that isn't the issue... hard to say for certain). I need a bit of clarification on the goal of setting up Single Table Inheritance, as well as some guidance to right my wrongs.

How do I go about creating another Customer and Employee, so I can run "rake db:migrate" without errors... unless you suggest I do something else?

Can you post your create_customers migration file?

Thankfully, I managed to hack it by creating both a customers and employees table for it to drop when i ran the migration... Thanks for offering to help, though. I probably should have tried that before posting the question :/
