Add columns to existing model

[Mike Dodge]

I am trying to add a couple columns to my existing model.  I found a good tutorial that showed how to create a migration and do it that way.  I followed all the steps, but my model is not updated and my DB is not updated.  But when I try to run the migrate command a second time, I get an error that says: "Duplicate column name"  so I know it is getting added somewhere.  Anyone know where that data is actually stored?

Here is the tutorial I followed: https://dev.to/nedsoft/add-new-fields-to-existing-sequelize-migration-3527
