The best way I follow to delete a model is, first run:

rake db:migrate:status

and if you are on rails 5 I think the command would be:

rails db:migrate:status

So this will show the status of your migration. If the migration is up then run:

rails db:migrate:down VERSION=version_no

or

rake db:migrate:down VERSION=version_no

Then you can safely destroy the model:

rails d model ModelName

So this will safely delete your model and migration files.

Hope this helps.
