a=["a","b","c"] a.pop="c" a is now ["a","b"] Is that what you want?

Would you like to remove the object that contains var3? var3 isn'' at the nested array, it''s a nested property of an object that is in there. If you wanted to remove it, it would be like this: var1[0].var2.delete_at( 0 ) - Maurício Linhares http://alinhavado.wordpress.com/ (pt-br) | http://blog.codevader.com/ (en) On Mon, Jan 26, 2009 at 5:50 AM, Ukrit Himakoon <rails-mailing-list-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> wrote:> > suppose that I''ve some kind of array like this > > var1[0].var2[0].var3 > > So I would like to remove var3 out of this nest array > what I should do? > > and after I tried to use delete It''s also delete some important value > out from database any idea?! > -- > Posted via http://www.ruby-forum.com/. > > > >--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
