Django的CBV和FBV

django提供了两种对应关系。

FBV: function base view
CBV:class base view

---

views.py中就是使用的FBV。

def index(request):
    return HttpResponse("Index")


def login(request):
    if request.method == 'GET':
        return render(request, 'login.html')
    elif request.method == 'POST':
        username = request.POST.get('username')
        password = request.POST.get('pwd')
        gender = request.POST.getlist('gender')
        intrest = request.POST.getlist('intrest')
        img1 = request.FILES.get('img1')
        print img1

        if username == 'a' and password == 'a':
            return render(request, 'index.html')
        else:
            return render(request, 'login.html')
    else:
        return redirect('index/')

urls.py中使用：

from app01 import views as app01_v

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^index/', app01_v.index),
    url(r'^login/', app01_v.login),
]

---

CBV的方式：

urls.py中：
调用类as_view() 方法（因为About是继承与View类的）。

from app01 import views as app01_v

urlpatterns = [
    url(r'^about/', app01_v.About.as_view()),
]

views.py中：

class About(View):
    def dispatch(self, request, *args, **kwargs):
        #调用父类dispatch   super这里调用的就是下面的get或者post
        result = super(About, self).dispatch(request, *args, **kwargs)
        return result

    def get(self, request):
        return render(request, 'about.html')
    def post(self, request):
        return render(request, 'about.html')
