Enye yamandla kaLaravel yi-syntax yayo enhle. Uma unamamodeli amaningi nobudlelwano eLaravel (ngenxa yamatafula amaningi asendaweni egciniwe), ukunqamula kuvame ukuphela ngekhodi engeyinhle kangako. Ngokuhamba kwesikhathi, izandiso ezintathu ezincane zikhombisile ukuthi zingifanele, engingathanda ukuzethula kafushane ngezansi. Sisebenzisa nje ifa elithile, izindlela zomlingo namaqoqo wangokwezifiso.
Okokuqala sakha imodeli entsha ngaphansi kohlelo lokusebenza \ ConvenienceModel.php:
b45e29b9125c2ab565b5526442437686
Ngemuva kwalokho sivumela wonke amamodeli ukuthi athole ifa kusuka ku- ConvenienceModel yethu entsha:
b45e29b9125c2ab565b5526442437686
Hlanganisa imisebenzi yakho nobudlelwano

b45e29b9125c2ab565b5526442437686
Uma manje ungeza i-logic yebhizinisi lakho, uthanda ukusebenzisa i-case (engezansi) yekesi lekesi:
b45e29b9125c2ab565b5526442437686
Sifuna ukulinganisa i-syntax yakho kokubili okwehlukile. Ukuze senze lokhu, sifaka indlela yomlingo __call ku- ConvenienceModel:
b45e29b9125c2ab565b5526442437686

Bheka izinto ezingenalutho
Uma ufuna ukukhipha igama lezwe kukheli lomuntu, uvame ukubona ikhodi elandelayo:
b45e29b9125c2ab565b5526442437686
Ukuvimbela lokhu, sifaka umtapo wezincwadi osebenza ngentambo bese sibuyisa into ekhethekile yesigaba esingenalutho uma imodeli ingatholakali:
b45e29b9125c2ab565b5526442437686
Lokhu futhi kwenza ucingo luphumelele (kulesi sibonelo, uma kutholakala okuthile, igama lezwe liyakhishwa, kuzo zonke ezinye izintambo zingenalutho).
b45e29b9125c2ab565b5526442437686
Uma futhi sifuna ukumboza icala lokuthi umsebenzisi one-ID 42 kungenzeka angabikho, sizokwakha nomsebenzi omncane womsizi walokhu:
b45e29b9125c2ab565b5526442437686
Le kholi elandelayo iletha intambo engenalutho noma ngabe umsebenzisi akekho nhlobo:
b45e29b9125c2ab565b5526442437686
Ukudabula kalula ubudlelwano be-n: m
Ekugcineni, sifuna ukwenza lula ikhodi elandelayo:
b45e29b9125c2ab565b5526442437686
Ngenxa yalokhu sisebenzisa amathuba amaqoqo wangokwezifiso . Siqala ngokwandisa imodeli elula:
b45e29b9125c2ab565b5526442437686
Ngemuva kwalokho sakha uhlelo lokusebenza lwefayela \ Helpers \ ConvenienceCollection.php , oluqinisekisa ukuthi ukubiza imisebenzi engaziwa kumaqoqo kwenza umsebenzi wazo zonke izinto eziseqoqweni:

Ngakho-ke singasebenzisa ikhodi elandelayo ukukhipha wonke amagama awo wonke amazwe kuwo wonke amakheli abo bonke abazali bomuntu:
b45e29b9125c2ab565b5526442437686
Kepha izingcingo ezinjengalezi ezilandelayo zingenzeka:
b45e29b9125c2ab565b5526442437686
Hlunga ngamakholomu amaningi
Ucingo olulandelayo luhlungwa kuphela ngendawo , noma ngabe lokho bekungeyona into obuyifuna:

Sandisa i-ConvenienceCollection ngomunye umsebenzi osizayo:
b45e29b9125c2ab565b5526442437686
Manje usunganikeza imodeli ngayinye umsebenzi wokuhlunga ojwayelekile ngamunye:
b45e29b9125c2ab565b5526442437686
Ngakho-ke singahlela iqoqo nge:
b45e29b9125c2ab565b5526442437686
Amagama ento
Imodeli ngayinye isebenzisa indlela ye-GetLabel (i-GetName iyahluka ngokuya ngemodeli):
b45e29b9125c2ab565b5526442437686
