Rails

Hi to all,
have active record model that has one to many relationship. This is
how it looks like:

ruby-1.9.2-p290 :001 >
@ukuizvj=Izvjestaj.new(:mjesec=>8, :godina=>2011,:djelatnik_id=>2)
=> #<Izvjestaj id: nil, godina: 2011, mjesec: 8, djelatnik_id: 2,
brojsati: nil, visak: nil, manjak: nil, nr: nil, rp: nil, komb: nil,
created_at: nil, updated_at: nil>

ruby-1.9.2-p290 :002 > @ukuizvj.izvjtipd
=> []

ruby-1.9.2-p290 :003 >
ntiprada=Izvjtipd.new(:tipneradni_id=>1, :vrijednost=>1)
=> #<Izvjtipd id: nil, izvjestaj_id: nil, tipneradni_id: 1,
vrijednost: 1, created_at: nil, updated_at: nil>

ruby-1.9.2-p290 :004 > @ukuizvj.izvjtipd << ntiprada
=> [#<Izvjtipd id: nil, izvjestaj_id: nil, tipneradni_id: 1,
vrijednost: 1, created_at: nil, updated_at: nil>]

ruby-1.9.2-p290 :005 > @ukuizvj.izvjtipd
=> [#<Izvjtipd id: nil, izvjestaj_id: nil, tipneradni_id: 1,
vrijednost: 1, created_at: nil, updated_at: nil>]

So, How can I address this value of @ukuizvj.izvjtipd? Problem is that
@ukuizvj.izvjtipd.find_by_tipneradni_id(1).vrijednost or
@ukuizvj.izvjtipd.where(:tipneradni_id=>1).vrijednost dont work until
I make @ukuizvj.save

Thank you

find_by_attribute and where statements both create sql statements which
are
executed when you access the records. since the record you’re looking
for
is not yet saved to the db, AR won’t find it using these methods.
