1.What is FBV and CBV
FBV means that the view function is in the form of a normal function; CBV means that the view function is in the form of a class.
2. Common FBV form
def index(request):
return HttpResponse('index')formality
3.1 Routing in the form of CBV
path（r'^login/',.as_view())
3.2 View functions in CBV form
from import View
class MyLogin(View):
def get(self,request): Functions executed on #get requests
return render(request,'')
def post(self,request): Functions executed on #post requests
return HttpResponse('post method')FBV and CBV each have their own merits
CBV features:
Able to match directly to the corresponding method execution based on the different request methods.
source code analysis
The core lies in the routing layer's .as_view() ---> In fact, calling the as_view() function is the same as calling the view() function inside the CBV, because the as_view() function is a closure function that returns the view ----> inside the view function returns the dispatch function ---> The dispatch function calls the corresponding function depending on how the request was made!
Three ways to add decorators
from import View Modules to be introduced for #CBV
from import method_decorator # Add modules to be introduced by the decorator
"""
CBV django does not recommend that you add a decorator directly to a class method.
Whether or not the decorator works, it is not recommended to add it directly.
"""
djangofor the benefit ofCBVThree methods are provided to add decorators
# @method_decorator(login_auth,name='get') # way 2 (you can add multiple decorators for different methods)
# @method_decorator(login_auth,name='post')
class MyLogin(View):
@method_decorator(login_auth) # 3: It works directly on all the methods of the current class.
def dispatch(self, request, *args, **kwargs):
return super().dispatch(request,*args,**kwargs)
# @method_decorator(login_auth) # Way 1: Name the method, add login_auth as decorator name directly to the method
def get(self,request):
return HttpResponse("get request")
def post(self,request):
