Indawo kaManyToMany
Intsimi ye-ManyToMany yintsimi yemodeli ye-Django evumela ukuba ugcine idatha malunga nezinto ezininzi. Le ndawo ingasetyenziselwa ukugcina ulwazi malunga nobudlelwane phakathi kwezinto ezahlukeneyo.
Umzekelo, unokusebenzisa indawo kaManyToMany ukugcina ulwazi malunga nobudlelwane phakathi kwabathengi kunye neeodolo. Kule meko, umthengi ngamnye uya kuba ne-odolo enye okanye ngaphezulu ehambelana nabo, kwaye iodolo nganye iya kuba nomthengi omnye okanye abaninzi abanxulumene nayo.
Ungasebenzisa indawo kaManyToMany kwiimodeli zakho ukulawula obu budlelwane ngokulula. Umzekelo, unokwenza imodeli ebizwa ngokuba yi-Order egcina iinkcukacha ze-odolo yomntu ngamnye, njenge-ID yomthengi, i-ID ye-odolo, kunye nemali epheleleyo ehlawulweyo. Unokwenza imodeli ebizwa ngokuba nguMthengi ogcina iinkcukacha zomthengi omnye, njenge-ID yomthengi kunye negama. Unokwenza indawo kaManyToMany ebizwa ngokuba yi-Orders_Customer edibanisa zonke iiodolo zomthengi onikiweyo kunye nabo bonke abathengi abanxulumene nezo odolo.
