what is the purpose of this code: return models.sequelize.sync().then(result =>{})? I altered my model and when i initialize the web app this code calls a create table statement defined with columns I removed from my model. I can't figure out how to remove the old columns. Does that make sense?

I've created my first model but only get the following error whenever I try to save an email address (Error: SequelizeValidationError: notNull Violation: cannot be null). I've judiciously followed your tutorial, so I'm not sure what's the problem. Thanks for any suggestion.
