**URL routing** (URLconf) yana shidar da URLs na buɗewar aiki zuwa **views** da suke jiyatarwa. Django yana daidaita URL da aka buɗa da jerin tsarin da ya ƙiri aiki da ya dace, yana ɗebawar wasu sigogi daga URL. ## Bayyana tsarin URL ```python # urls.py from django.urls import path from . import views urlpatterns = [ path("", views.home, name="home"), # / path("articles/", views.article_list, name="article_list"), # /articles/ path("articles//", views.article_detail, name="detail"), # /articles/5/ path("articles//", views.by_slug, name="by_slug"), # /articles/my-post/ ] ``` Kowane `path()` yana shidar da tsarin URL zuwa aikin view. Django yana gwada su daga bisa zuwa kasa da yana amfani da daidai na farko. ## Tafi da sigogi daga URL ```python path("articles//", views.article_detail) # captures an integer as `pk` # the view receives the captured value as a parameter def article_detail(request, pk): # pk = 5 for /articles/5/ article = Article.objects.get(pk=pk) ``` Masu jujjuya hanya (``, ``, ``, ``) suna kama da ɗabaɗaɓɓun bangarorin URL da ɗabaɗɓun su ta hanyar bayani, suna tura su zuwa view a matsayin argumminti. ## URLs da suna da wariya da maimaita gaida (mahimmanci!) ```python path("articles//", views.article_detail, name="detail") # the `name` ``` ```python # generate URLs by NAME instead of hardcoding them — DRY and refactor-safe from django.urls import reverse url = reverse("detail", kwargs={"pk": 5}) # → "/articles/5/" redirect("detail", pk=5) # in views ``` ```html Read more ``` **URLs da suna** suna da mahimmanci: ta wurin komawa ga URLs ta wurin `name` (ta hanyar `{% url %}` a gidajen kira da `reverse()` a code) maimakon tsure hanya, kuna iya canja tsarin URL a wuri ɗaya ba tare da karni kowane hanyar - DRY, jiyya aiki mai ammaci. ## Haɗa URLs na app (modular routing) ```python # project urls.py — delegate to each app's URLconf from django.urls import include, path urlpatterns = [ path("blog/", include("blog.urls")), # /blog/... handled by the blog app path("shop/", include("shop.urls")), path("admin/", admin.site.urls), ] ``` `include()` yana aiwatar da takardar URL zuwa app's sariri `urls.py`, yana ɗaukan routing modular da kowane app mai kasuwa. ## Dalilin da yasa ya yi matukar mahimmanci URL routing shafi ne mahimmanci ga kowane aikace-aikacen Django — yana bayyana tsarin URL na gida da shi ne yadda buɗewar aiki ke isa ido daya.
