rails generate migration DropProductsTable

Good

class DropUsers < ActiveRecord::Migration
 def up
 drop_table :users
 end

 def down
 fail ActiveRecord::IrreversibleMigration
 end
end

Better (can reversible)

class DropUsers < ActiveRecord::Migration
 def change
 drop_table :users do |t|
 t.string :email, null: false
 t.timestamps null: false
 end
 end
end
