An error has occurred, this and all later migrations canceled:

The single-table inheritance mechanism failed to locate the subclass: 'Spree::Calculator::Ups::ThreeDaySelect'. This error is raised because the column 'type' is reserved for storing the class in case of inheritance. Please rename this column if you didn't intend it to be used for storing the inheritance class or overwrite Spree::Calculator.inheritance_column to use another column for that information./Users/nate/Projects/Websites/spree-fine-line-automation/db/migrate/20131215195190_migrate_old_shipping_calculators.spree.rb:5:in `block in up'
