Question

我是Django的新手，我想创建一个应用程序，使选定的用户能够登录，然后上传文件，然后再对其进行处理。

models.py

class Profile(models.Model):
    username = models.OneToOneField(User, on_delete=models.CASCADE)
    password = models.TextField(max_length=80,blank=True)
    company = models.TextField(max_length=80, blank=True)

    @receiver(post_save, sender=User)
    def create_user_profile(sender, instance, created, **kwargs):
        if created:
            Profile.objects.create(user=instance)


    @receiver(post_save, sender=User)
    def save_user_profile(sender, instance, **kwargs):
        instance.profile.save()

class Document(models.Model):
    uploaded_by = models.ForeignKey(Profile,on_delete=models.CASCADE)
    date_uploaded = models.DateTimeField(auto_now_add=True)

forms.py

class LoginForm(forms.Form):
    username = forms.CharField()
    password = forms.CharField(widget=forms.PasswordInput)
    company = forms.CharField()

class DocumentForm(forms.Form):
    docfile = forms.FileField(label='Select a file')

malex.urls（应用程序网址）

from malex.views import list
from malex.views import login 

urlpatterns = [
    url(r'^list/$', list, name='list'),
    url(r'^login/$', login, name='login'),
]

项目/网址

urlpatterns = [
    path('admin/', admin.site.urls),
    url(r'^newp/', include('malex.urls')),
]

views.py

def login(request):
    if request.method == 'POST':
        form = LoginForm(request.POST)
        if form.is_valid():
            cd = form.cleaned_data
            user = authenticate(user=cd['user'],password=cd['password'],company=cd['company'])
            if user is not None:
                if user is active:
                    login(request,user)
                    return HttpResponse('Authenticated successfully')
                else:
                    return HttpResponse('Disabled account')
            else:
                return HttpResponse('Invalid login')
    else:
        form=LoginForm()

    return render(request,'account/login.html',{'form': form})



def list(request):
    # Handle file upload
    if request.method == 'POST':
        form = DocumentForm(request.POST, request.FILES)
        if form.is_valid():
            newdoc = Document(docfile=request.FILES['docfile'])
            newdoc.save()

            # Redirect to the document list after POST
            return HttpResponseRedirect(reverse('list'))

现在，登录和上传操作已分开。如何更改我的视图和网址以先登录然后再上传？我需要在装饰器中使用基于类的视图吗？

创建自定义登录表单并查看。
使用您的localhost：8000地址作为登录模板

(app) urlpatterns = [path('',views.loginview,name = 'login')]

(project) urlpatterns = [path('', include('malex.urls')),)]
使用{% block content %}{% endblock %}
在模板或视图中使用通过限制{% if request.user.is_authenticated %}，让他们访问upload section。

如何重组我的Django代码？
