Rails Tip on how to drop a table using migrations

Drop Table

rails generate migration DropSomeTable  (where some is your table name)
It will generate a timestamped migration. They key is to place the drop table command in the up section

class DropSomeTable < ActiveRecord::Migration
  def up
    drop_table :some
  end

  def down
    raise ActiveRecord::IrreversibleMigration <--optional
  end
end

then run rake db:migrate VERSION=20140722133854, where the version is the timestamp on the file name. You should see it dropping the table and the schema.rb should change accordingly.

Note the file name will be 20140722133854_drop_some_table.rb
