Django Web Geli\u015ftirmede View’lar Olu\u015fturma: Kapsaml\u0131 Bir Rehber<\/h2>\n

Django, Python ile h\u0131zl\u0131 ve verimli web uygulamalar\u0131 geli\u015ftirmek i\u00e7in pop\u00fcler bir a\u00e7\u0131k kaynak web \u00e7at\u0131s\u0131d\u0131r. Django’nun mimarisi, Model-View-Template (MVT) olarak bilinen bir deseni takip eder. Bu desende “View” katman\u0131, bir web iste\u011fini (request) al\u0131r, i\u015f mant\u0131\u011f\u0131n\u0131 y\u00fcr\u00fct\u00fcr ve bir web yan\u0131t\u0131 (response) d\u00f6nd\u00fcr\u00fcr. K\u0131sacas\u0131, bir web sayfas\u0131n\u0131 g\u00f6r\u00fcnt\u00fclemek, bir form g\u00f6ndermek, bir API iste\u011fini i\u015flemek veya bir veritaban\u0131 kayd\u0131n\u0131 de\u011fi\u015ftirmek gibi t\u00fcm etkile\u015fimler View’lar arac\u0131l\u0131\u011f\u0131yla ger\u00e7ekle\u015fir. Bu makale, Django’da View’lar\u0131n nas\u0131l olu\u015fturulaca\u011f\u0131n\u0131, farkl\u0131 t\u00fcrlerini, geli\u015fmi\u015f konular\u0131 ve en iyi uygulamalar\u0131 derinlemesine inceleyecektir.<\/p>\n

Giri\u015f: Django View Nedir ve Neden \u00d6nemlidir?<\/h3>\n

Django’da bir “View”, web uygulaman\u0131z\u0131n belirli bir URL’ye (Uniform Resource Locator) gelen isteklere nas\u0131l yan\u0131t verece\u011fini tan\u0131mlayan bir Python fonksiyonu veya s\u0131n\u0131f\u0131d\u0131r. Bir kullan\u0131c\u0131 web taray\u0131c\u0131s\u0131na bir URL yazd\u0131\u011f\u0131nda veya bir ba\u011flant\u0131ya t\u0131klad\u0131\u011f\u0131nda, Django’nun URL y\u00f6nlendiricisi (URL dispatcher) bu iste\u011fi uygun View’a y\u00f6nlendirir. View, iste\u011fi i\u015fler, gerekirse veritaban\u0131ndan veri al\u0131r (Model ile etkile\u015fim), bu verileri bir \u015fablonla birle\u015ftirir (Template ile etkile\u015fim) ve son olarak kullan\u0131c\u0131n\u0131n taray\u0131c\u0131s\u0131na bir HTTP yan\u0131t\u0131 g\u00f6nderir.<\/p>\n

View’lar, web uygulaman\u0131z\u0131n “beyni” gibidir. Kullan\u0131c\u0131 etkile\u015fimlerini y\u00f6netir, i\u015f ak\u0131\u015flar\u0131n\u0131 kontrol eder ve nihayetinde kullan\u0131c\u0131n\u0131n g\u00f6rd\u00fc\u011f\u00fc ve etkile\u015fimde bulundu\u011fu i\u00e7eri\u011fi olu\u015fturur. Bu nedenle, sa\u011flam, g\u00fcvenli ve bak\u0131m\u0131 kolay View’lar olu\u015fturmak, ba\u015far\u0131l\u0131 bir Django projesi i\u00e7in kritik \u00f6neme sahiptir.<\/p>\n

Temel View Kavramlar\u0131<\/h3>\n

Her Django View’unun merkezinde iki ana kavram bulunur: HttpRequest<\/code> nesnesi ve HttpResponse<\/code> nesnesi.<\/p>\n

Request ve Response Nesneleri<\/h4>\n

Bir kullan\u0131c\u0131 taray\u0131c\u0131s\u0131ndan sunucuya bir istek g\u00f6nderdi\u011finde, Django bu iste\u011fi bir HttpRequest<\/code> nesnesi olarak paketler. Bu nesne, gelen istek hakk\u0131nda t\u00fcm bilgileri i\u00e7erir:<\/p>\n

* request.method<\/code><\/strong>: \u0130ste\u011fin HTTP metodu (GET, POST, PUT, DELETE vb.).
\n* request.GET<\/code><\/strong>: GET parametrelerini i\u00e7eren bir s\u00f6zl\u00fck benzeri nesne.
\n* request.POST<\/code><\/strong>: POST parametrelerini i\u00e7eren bir s\u00f6zl\u00fck benzeri nesne (form verileri).
\n* request.COOKIES<\/code><\/strong>: \u00c7erezleri i\u00e7eren bir Python s\u00f6zl\u00fc\u011f\u00fc.
\n* request.FILES<\/code><\/strong>: Y\u00fcklenen dosyalar\u0131 i\u00e7eren bir s\u00f6zl\u00fck benzeri nesne.
\n* request.user<\/code><\/strong>: Oturum a\u00e7m\u0131\u015f kullan\u0131c\u0131y\u0131 temsil eden bir User<\/code> nesnesi (e\u011fer django.contrib.auth<\/code> kullan\u0131l\u0131yorsa).
\n* request.path<\/code><\/strong>: \u0130ste\u011fin tam yolu (\u00f6rne\u011fin, \/urunler\/123\/<\/code>).
\n* request.META<\/code><\/strong>: T\u00fcm mevcut HTTP ba\u015fl\u0131klar\u0131n\u0131 i\u00e7eren standart bir Python s\u00f6zl\u00fc\u011f\u00fc.<\/p>\n

View, bu HttpRequest<\/code> nesnesini i\u015fledikten sonra, bir HttpResponse<\/code> nesnesi d\u00f6nd\u00fcrmelidir. Bu nesne, kullan\u0131c\u0131n\u0131n taray\u0131c\u0131s\u0131na geri g\u00f6nderilecek i\u00e7eri\u011fi ve di\u011fer HTTP bilgilerini ta\u015f\u0131r:<\/p>\n

* HttpResponse(content='Merhaba D\u00fcnya', content_type='text\/plain', status=200)<\/code><\/strong>: Temel bir yan\u0131t olu\u015fturur. content<\/code> yan\u0131t\u0131n g\u00f6vdesini, content_type<\/code> i\u00e7eri\u011fin t\u00fcr\u00fcn\u00fc ve status<\/code> HTTP durum kodunu belirtir.
\n* JsonResponse<\/code><\/strong>: JSON format\u0131nda veri d\u00f6nd\u00fcrmek i\u00e7in \u00f6zel bir HttpResponse<\/code> alt s\u0131n\u0131f\u0131d\u0131r. \u00d6zellikle API’ler i\u00e7in kullan\u0131\u015fl\u0131d\u0131r.
\n* HttpResponseRedirect<\/code><\/strong>: Kullan\u0131c\u0131y\u0131 farkl\u0131 bir URL’ye y\u00f6nlendirmek i\u00e7in kullan\u0131l\u0131r.
\n* render()<\/code> k\u0131sayolu<\/strong>: Genellikle bir \u015fablonu i\u015fleyip HttpResponse<\/code> d\u00f6nd\u00fcrmek i\u00e7in kullan\u0131lan bir fonksiyondur.<\/p>\n

View Fonksiyonlar\u0131n\u0131n Yap\u0131s\u0131<\/h4>\n

En basit haliyle, bir Django View’u, HttpRequest<\/code> nesnesini ilk arg\u00fcman olarak alan bir Python fonksiyonudur.<\/p>\n

# myapp\/views.py\n\nfrom django.http import HttpResponse\n\ndef merhaba_dunya(request):\n    return HttpResponse(\"\")<\/code><\/pre>\n
Bu fonksiyon, \/merhaba\/<\/code> gibi bir URL’ye gelen iste\u011fi i\u015fleyecek ve “Merhaba D\u00fcnya!” metnini bir H1 etiketi i\u00e7inde taray\u0131c\u0131ya g\u00f6nderecektir.<\/p>\n
Fonksiyon Tabanl\u0131 View’lar (FBV’ler)<\/h3>\n
Fonksiyon Tabanl\u0131 View’lar (Function-Based Views – FBV’ler), Django’da View olu\u015fturman\u0131n en temel ve anla\u015f\u0131l\u0131r yoludur. Basit uygulamalar ve belirli bir i\u015flevi yerine getiren View’lar i\u00e7in m\u00fckemmel bir se\u00e7imdir.<\/p>\n
Basit Bir FBV Olu\u015fturma<\/h4>\n
\u00d6nceki \u00f6rne\u011fimiz, basit bir FBV’ye iyi bir \u00f6rnekti. \u015eimdi bunu bir Django projesine entegre edelim.<\/p>\n
1.  myapp\/views.py<\/code> i\u00e7inde View’u tan\u0131mlay\u0131n:<\/strong><\/p>\n
# myapp\/views.py\n    from django.http import HttpResponse\n\n    def anasayfa(request):\n        return HttpResponse(\"Ana Sayfaya Ho\u015f Geldiniz!\")<\/code><\/pre>\n
2.  myapp\/urls.py<\/code> i\u00e7inde URL’yi yap\u0131land\u0131r\u0131n:<\/strong>
\n    E\u011fer myapp<\/code> i\u00e7inde bir urls.py<\/code> dosyas\u0131 yoksa, olu\u015fturun:<\/p>\n
# myapp\/urls.py\n    from django.urls import path\n    from . import views\n\n    urlpatterns = [\n        path('', views.anasayfa, name='anasayfa'),\n    ]<\/code><\/pre>\n
3.  Projenizin ana urls.py<\/code> dosyas\u0131na dahil edin:<\/strong><\/p>\n
# myproject\/urls.py\n    from django.contrib import admin\n    from django.urls import path, include\n\n    urlpatterns = [\n        path('admin\/', admin.site.urls),\n        path('', include('myapp.urls')), # myapp'in URL'lerini dahil et\n    ]<\/code><\/pre>\n
    Art\u0131k, taray\u0131c\u0131n\u0131zda http:\/\/127.0.0.1:8000\/<\/code> adresine gitti\u011finizde “Ana Sayfaya Ho\u015f Geldiniz!” mesaj\u0131n\u0131 g\u00f6rmelisiniz.<\/p>\n
\u015eablon Kullan\u0131m\u0131<\/h4>\n
\u00c7o\u011fu web uygulamas\u0131, statik metinler yerine dinamik HTML i\u00e7eri\u011fi sunar. Django’nun \u015fablon sistemi, Python kodunu HTML’den ay\u0131rarak View’lar\u0131n daha d\u00fczenli olmas\u0131n\u0131 sa\u011flar. render()<\/code> k\u0131sayolu, bir \u015fablonu y\u00fcklemek, bir ba\u011flam (context) ile i\u015flemek ve HttpResponse<\/code> olarak d\u00f6nd\u00fcrmek i\u00e7in kullan\u0131l\u0131r.<\/p>\n
