ruby - Is there a more efficient way of ensuring my database gets closed? -

i'm using daybreak library, key/value store.

i open perform operation this:

db = daybreak::db.new $showdatabasename

then whatever want, , close this:

db.close

it seems wasted effort everywhere want use however. seems might more efficient declare class variable in initialize this:

def initialize      @db = daybreak::db.new $showdatabasename  end

it means rest of class can use without initializing , closing each time, message reading:

daybreak database not closed, state might inconsistent

is there better way of doing this, deals both repetition , warning?

use block:

def use_db(database_name)   db = daybreak::db.new(database_name)   yield db ensure    db.close end  use_db($showdatabasename) |db|   # db end
