Having trouble with this rails polymorphic migration challenge

I'm trying to do this challenge: https://teamtreehouse.com/library/active-record-associations-in-rails/more-association-options/a-migration-for-a-polymorphic-association, and I'm looking at the teachers notes from the previous video as a template: https://teamtreehouse.com/library/polymorphic-options

I tried both of these options, but neither works:

bin/rails g migration AddVehicleToPart vehicle_id:integer vehicle_type:string
bin/rails g migration AddVehicleToPart vehicle:references{polymorphic}

OK, so this is the code that worked for me in the challenge:

rails g migration AddVehicleToParts vehicle_id:integer vehicle_type:string

You should use the plural name of the table to which you're adding stuff (Parts in this case), Rails will then infer that this is the name of the table in your database.
