Django登录表单未进行身份验证

尝试使用基于类的视图创建登录视图（第一次），所有内容都会被填充，但它一直说我的用户名无效。请帮我找出哪里出了问题

login.html（编辑以显示整个表单）：

forms.py

class LoginForm(forms.Form):
    username = forms.CharField(max_length=255, required=True)
    password = forms.CharField(widget=forms.PasswordInput, required=True)

    def clean(self):
        username = self.cleaned_data.get('username')
        password = self.cleaned_data.get('password')
        user = authenticate(username=username, password=password)
        if not user or not user.is_active:
            raise forms.ValidationError("Sorry, that login was invalid. Please try again.")
        return self.cleaned_data

    def login(self, request):
        username = self.cleaned_data.get('username')
        password = self.cleaned_data.get('password')
        user = authenticate(username=username, password=password)
        return user

app_name = 'dispatch'

urlpatterns = [
    url(r'^$', views.IndexView.as_view(), name='index'),
    url(r'^accounts/login/$', views.LoginView.as_view(), name='login'),
    url(r'^logout/$', views.LogoutView.as_view(), {'next_page': '/accounts/login'}, name='logout'),
    url(r'^profile/(?P<pk>\d+)/$', views.ProfileDetailView.as_view(), name='profile_detail'),
]

url.py

class LoginForm(forms.Form):
    username = forms.CharField(max_length=255, required=True)
    password = forms.CharField(widget=forms.PasswordInput, required=True)

    def clean(self):
        username = self.cleaned_data.get('username')
        password = self.cleaned_data.get('password')
        user = authenticate(username=username, password=password)
        if not user or not user.is_active:
            raise forms.ValidationError("Sorry, that login was invalid. Please try again.")
        return self.cleaned_data

    def login(self, request):
        username = self.cleaned_data.get('username')
        password = self.cleaned_data.get('password')
        user = authenticate(username=username, password=password)
        return user

app_name = 'dispatch'

urlpatterns = [
    url(r'^$', views.IndexView.as_view(), name='index'),
    url(r'^accounts/login/$', views.LoginView.as_view(), name='login'),
    url(r'^logout/$', views.LogoutView.as_view(), {'next_page': '/accounts/login'}, name='logout'),
    url(r'^profile/(?P<pk>\d+)/$', views.ProfileDetailView.as_view(), name='profile_detail'),
]

app_name='dispatch'
URL模式=[
url（r'^$'，views.IndexView.as_view（），name='index'），
url（r“^accounts/login/$”，views.LoginView.as_view（），name='login'），
url（r“^logout/$”，views.LogoutView.as_view（），{'next_page'：'/accounts/login'}，name='logout'），
url（r“^profile/（？P\d+/$”，views.ProfileDetailView.as_view（），name='profile_detail'），
]

我不知道为什么那个教程会让它变得如此复杂，但你所要做的就是扩展默认的登录视图，添加你的

get\u success\u url

函数和

模板\u name

from django.contrib.auth.views import LoginView as AuthLoginView

class LoginView(AuthLoginView):
    success_url = '/'
    template_name = 'pages/login.html'
    redirect_field_name = REDIRECT_FIELD_NAME

    def get_success_url(self):
        redirect_to = self.request.GET.get(self.redirect_field_name)
        if not is_safe_url(url=redirect_to, host=self.request.get_host()):
            redirect_to = self.success_url
        return redirect_to

编辑：您的表单缺少输入上的

名称

属性。这就是django寻找值的地方

<input type="text" name="{{ form.username.name }}" />
<input type="password" name="{{ form.password.name }}" />

登录视图是否来自django 1.11？我无法导入名称LoginView。在我的应用程序中使用Django 1.10。将Django升级到1.11以修复导入错误，现在它根本不尝试进行身份验证。只需重新加载页面是的…这是相当长的思考至少上面的整个表单编辑的答案，看看它
