After creating the migration file for deletion,
$ rails g migration DropUsers
I couldn't find the official one, but it would be nice to edit it in such a way that it can be rolled back.
db/migrate/20201214000000_drop_users.rb
class DropUsers < ActiveRecord::Migration
def change
drop_table :users do |t|
t.string :email, null: false
t.timestamps #In Rails 5 t.Columns created with timestamps are not needed because they are NOT NULL by default.
end
end
end
