验证用户是否登录

# 开始在用户登录的时候验证结束后login登录

# request.user.is_authenticated()

{% if request.user.is_authenticated %}

# 函数用这样的装饰器

from django.contrib.auth.decorators import login_required

@login_required

# 类用这样的基础登录函数

(minxi表示一些基础的类)

from django.contrib.auth.decorators import login_required

from django.utils.decorators import method_decorator

class LoginRequiredMixin(object):

    @method_decorator((login_required(login_url='/login/')))

    def dispatch(self, request, *args, **kwargs):

        return super(LoginRequiredMixin, self).dispatch(request, *args, **kwargs)

在视图中应该这样写

class CourseCommentView(LoginRequiredMixin, View)
