Django —— View

Django —— View

Django中视图设计的两种模式：FBV 和 CBV。

FBV，Function Base View。

# ===== url =====
from django.conf.urls import url
from django.contrib import admin
from app01 import views

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^employee/', views.employee),
]


# ===== view =====
from django.shortcuts import render, HttpResponse

def employee(request):
    return HttpResponse("职员页面")

# 当访问该url时，执行该函数 employee()。

 

CBV，Class Base View。

# ===== url===== 
from django.conf.urls import url
from django.contrib import admin
from app01 import views

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^student/', views.Studentview.as_view()),
]


# ===== view ===== 
from django.shortcuts import render, HttpResponse
from django.views import View

class Studentview(MView):
    def get(self, request, *args, **kwargs):
        return HttpResponse("学生页面，GET方法")

    def post(self, request, *args, **kwargs):
        return HttpResponse("学生页面，POST方法")

# 访问该url，会根据请求方式执行相应的方法。
# 请求方式：get、post、put、delete、patch、head、options、trace
