View FBV function (function base views) based
CBV class-based view (class base views)
That is our view - is to write a function or class written viewsWe look at two simple implementation
urlpatterns = [
path(‘admin/‘, admin.site.urls),
path(‘test_fbv‘, test_fbv), #FBV
path(‘test_cbv‘, TestCBV.as_view()) #CBV]
def test_fbv(request): ##函数式视图
return HttpResponse("ok")
class TestCBV (View): ## Class formula view
DEF GET (Self, Request):
return the HttpResponse ( "OK")
the CBV performs as_view () method,
a. Interface Development
urlpatterns = [
# url(r'^admin/', admin.site.urls),
url(r'^get_order/', views.get_order),
url(r'^add_order/', views.add_order),
url(r'^del_order/', views.del_order),
url(r'^update_order/', views.update_order),
]
def get_order(request):
return HttpResponse('')
def add_order(request):
return HttpResponse('')
def del_order(request):
return HttpResponse('')
def update_order(request):
return HttpResponse('')
b. restful specification (recommended)
1. 根据method不同做不同的操作，示例：
基于FBV:
urlpatterns = [
url(r'^order/', views.order),
]
def order(request):
if request.method == 'GET':
return HttpResponse('获取订单')
elif request.method == 'POST':
return HttpResponse('创建订单')
elif request.method == 'PUT':
return HttpResponse('更新订单')
elif request.method == 'DELETE':
return HttpResponse('删除订单')
基于CBV:
urlpatterns = [
url(r'^order/', views.OrderView.as_view()),
]
class OrderView(View):
def get(self,request,*args,**kwargs):
return HttpResponse('获取订单')
def post(self,request,*args,**kwargs):
return HttpResponse('创建订单')
def put(self,request,*args,**kwargs):
return HttpResponse('更新订单')
def delete(self,request,*args,**kwargs):
return HttpResponse('删除订单')
