Django 视图装饰器的使用

可以直接装饰在方法上

from django.contrib.auth.decorators import login_required
from django.utils.decorators import method_decorator
from django.views.generic import TemplateView

class ProtectedView(TemplateView):
    template_name = 'secret.html'

    @method_decorator(login_required)
    def dispatch(self, *args, **kwargs):
        return super().dispatch(*args, **kwargs)

 

装饰在类上

@method_decorator(login_required, name='dispatch')  # 这里写要装饰的方法
class ProtectedView(TemplateView):
    template_name = 'secret.html'

 

通过列表

decorators = [never_cache, login_required]
@method_decorator(decorators, name='dispatch')
class ProtectedView(TemplateView):
    template_name = 'secret.html'



#########   两种方法是一样的  ##############
@method_decorator(never_cache, name='dispatch')
@method_decorator(login_required, name='dispatch')
class ProtectedView(TemplateView):
    template_name = 'secret.html'
