python - 登录 Django 时帐户未进行身份验证

Question

我可以注册帐户并将数据上传到MYSQL数据库，但帐户没有“身份验证”

views.py

from django.core.urlresolvers import reverse_lazy
from django.views.generic import FormView, TemplateView
from django.shortcuts import redirect, get_object_or_404, render, render_to_response
from django.contrib.auth import authenticate, login, logout
from django.contrib.auth.models import User
from django.contrib.auth.decorators import login_required
from django.template import RequestContext
from django.contrib import messages, auth
from django.http import HttpResponseRedirect, HttpResponse
from django.core.context_processors import csrf
from mongoengine.queryset import DoesNotExist

from .forms import *

class RegisterView(FormView):
    template_name = 'registration/register.html'
    form_class = UserCreationForm
    success_url = reverse_lazy('registered')

    def form_valid(self, form):
        form.save()
        return FormView.form_valid(self, form)

register = RegisterView.as_view()


class RegisteredView(TemplateView):
    template_name = 'registration/registered.html'

registered = RegisteredView.as_view()

def login(request):
    c = {}
    c.update(csrf(request))
    return render_to_response('registration/auth.html', c)

def auth_view(request):
    username = request.POST['username']
    password = request.POST['password']
    user = authenticate(username=username, password=password)
    if user is not None:
        if user.is_active:
             login(request, user)
        else:
          return HttpResponseRedirect('/inactive')
     else:
          return HttpResponseRedirect('/invalid')

def loggedin(request):
    return render_to_response('registration/hello.html', 
                          {'full_name': request.user.username})

def invalid_login(request):
    return render_to_response('registration/hello.html')

Auth_view() 负责处理登录。

基本上，无论我做什么，它总是会遇到带有未知错误标志的“异常(exception):”。我觉得它甚至没有连接 MYSQL 数据库并“验证”

编辑:更新了 Views.py/auth_view()

用户创建表单 (forms.py)

   class UserCreationForm(forms.Form):
        error_messages = {
            'duplicate_username': _("A user with that username already exists."),
            'password_mismatch': _("The two password fields didn't match."),
        }
        username = forms.RegexField(label=_("Username"), max_length=30,
            regex=r'^[\w.@+-]+$',
            help_text=_("Required. 30 characters or fewer. Letters, digits and "
                      "@/./+/-/_ only."),
        error_messages={
              'invalid': _("This value may contain only letters, numbers and "
                          "@/./+/-/_ characters.")})
    email = forms.EmailField(label=_("Email"), max_length=254,
        help_text=_("Required valid email. 254 characters or fewer."),
        error_messages={
            'invalid': _("This value may contain only valid email address.")})
    password1 = forms.CharField(label=_("Password"),
        widget=forms.PasswordInput)
    password2 = forms.CharField(label=_("Password confirmation"),
        widget=forms.PasswordInput,
        help_text=_("Enter the same password as above, for verification."))

    def clean_username(self):
        username = self.cleaned_data["username"]
        try:
             User._default_manager.get(username=username)
         except User.DoesNotExist:
             return username
        raise forms.ValidationError(
            self.error_messages['duplicate_username'],
           code='duplicate_username',
        )

    def clean_password2(self):
        password1 = self.cleaned_data.get("password1")
        password2 = self.cleaned_data.get("password2")
        if password1 and password2 and password1 != password2:
            raise forms.ValidationError(
                self.error_messages['password_mismatch'],
                code='password_mismatch',
            )
        return password2

    def save(self):
        user = User._default_manager.create_user(
             username=self.cleaned_data['username'],
             email=self.cleaned_data['email'],
             password=self.cleaned_data["password1"])
        return user

Answer 1

嗯，我认为你必须使用 django 的身份验证:

user = authenticate(username=username, password=password)

有关如何使用 django 身份验证的更多信息，请参阅此页面:

https://docs.djangoproject.com/en/dev/topics/auth/default/#auth-web-requests

顺便说一句，如果你可以注册用户，这意味着你的 django 应用程序与数据库连接良好，问题一定出在其他地方。
