Model za oglas. Vsebuje lastnosti, ki definirajo strukturo oglasa in sovpadajo s stolpci v bazi.
Nekatere metode so statične, ker niso vezane na posamezen oglas: poišči vse oglase, vstavi nov oglas, ...
Druge so statične, ker so vezane na posamezen oglas: posodobi oglas, izbriši oglas, ...
V modelu moramo definirati tudi relacije oz. povezane entitete/modele. V primeru oglasa je to $user, ki
povezuje oglas z uporabnikom, ki je oglas objavil. Relacija nam poskrbi za nalaganje podatkov o uporabniku,
da nimamo samo user_id, ampak tudi username, ...
