将django.contrib.auth.views重新实现为基于类的视图。
django-class-auth-views的Python项目详细描述
安装
pip install django-class-auth-views
基本用法
与其将django.contrib.auth.login包含到urls.py中，不如使用此项目提供的一个。 urls.py：
from class_based_auth_views.views import LoginView, LogoutView
urlpatterns = patterns('',
url(r'^login/$', LoginView.as_view(form_class=EmailAsUsernameAuthenticationForm), name="login"),
url(r'^logout/$', LogoutView.as_view(), name="logout"),
)
请注意，logout视图需要POST才能真正注销。所以registration/logout.html模板 应该包含一个带有提交按钮的表单。
扩展loginview示例
既然loginview是基于一般的基于类的视图的，那么扩展起来就容易多了。假设您需要实现 使用一次性密码的两步登录过程：
from django.contrib.auth import login
class PhaseOneLoginView(LoginView):
def form_valid(self, form):
"""
Forces superusers to login in a 2 step process (One Time Password). Other users are logged in normally
"""
user = form.get_user()
if user.is_superuser:
self.save_user(user)
return HttpResponseRedirect(self.get_phase_two_url())
else:
login(self.request, user)
return HttpResponseRedirect(self.get_success_url())
def get_phase_two_url(self):
return reverse('phase_two_login')
def save_user(self, user):
self.request.session['otp_user'] = user
class PhaseTwoLoginView(FormView):
form_class = OTPTokenForm
def get_user(self):
return self.request.session.get('otp_user', None)
def clean_user(self):
if 'otp_user' in self.request.session:
del self.request.session['otp_user']
def form_valid(self, form):
code = form.cleaned_data.get('code')
user = self.get_user()
login(request, user)
