django 用户登录

django已经做好用户登录及权限相关的功能，我们只需要使用就可以了。

login页面

        {% csrf_token %}
        

          
          

            

              
            
          
        
        

          
          

            

              
            
          
        
        

            Sign In
        
      

view

from django.shortcuts import redirect
from django.views.generic.base import View, TemplateView
from django.contrib.auth import authenticate, login, logout

class LoginView(TemplateView):
    template_name = 'site/login.html'


class LoginInView(View):
    def post(self, request, *args, **kwargs):
        username = request.POST.get('login')
        password = request.POST.get('secret')
        user = authenticate(request, username=username, password=password)
        print(user)
        if user is not None:
            login(request, user)
            return redirect('/backend/config/index')
        else:
            return redirect('/backend/login')

class LoginOutView(View):
    def get(self, request, *args, **kwargs):
        logout(request)
        return redirect('/backend/login')

url

path('login', LoginView.as_view(), name = 'login'),
path('login-in', LoginInView.as_view(), name = 'login-in'),
path('login-out', LoginOutView.as_view(), name = 'login-out'),

 

页面登录验证

由于我自定义了登录页面，所以需要覆盖默认跳转登录页面。

from django.contrib.auth.mixins import LoginRequiredMixin

class BackendLoginRequiredMinix(LoginRequiredMixin):
    login_url = '/backend/login'
    redirect_field_name = 'redirect_to'

使用

from backend.helps.BackendLoginRequiredMinix import BackendLoginRequiredMinix

class AdvPositionIndexView(BackendLoginRequiredMinix, ListView):
    model = AdvPosition # 指定模型
    context_object_name = 'grid' # 默认object_list
    paginate_by = 2 # 每页显示数量 默认Paginator实例 page_obj
    ordering = ['-id'] # 默认排序
    template_name = 'adv-position/index.html'
