Django用户模型文件字段更新错误

Question

所以我有一个用户模型一对一的字段有两个文件字段，我上传这两个文件没有问题，但是当我尝试更改文件时，我得到了这个：

model.py ：

from django.db import models
from django.contrib.auth.models import User


class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    demand_file = models.FileField(upload_to='archivos', blank=True, validators=[validate_file_extension])
    order_file = models.FileField(upload_to='archivos', blank=True, validators=[validate_file_extension])

view.py

@login_required
def upload_files(request):

    if request.method == 'POST':
        form = UserFileUploadForm(request.POST, request.FILES)
        if form.is_valid():
            profile = form.save(commit=False)
            profile.user = request.user
            profile.save()
            return HttpResponseRedirect(reverse('index'))
        else:
            messages.info(request, 'Archivo no valido, por favor ingrese un archivo CSV')
            return render(request, 'project_app/file_upload.html', {'uploads': form})
    else:

        form = UserFileUploadForm()
        return render(request, 'project_app/file_upload.html', {'uploads': form})

forms.py

class UserForm(forms.ModelForm):
    password = forms.CharField(widget=forms.PasswordInput())

    class Meta:
        model = User
        fields = ('username', 'password')


class UserFileUploadForm(forms.ModelForm):

    class Meta:
        model = Profile
        fields = ('demand_file', 'order_file')

在控制台中我得到了

  

django.db.utils.IntegrityError：NOT NULL约束失败：project_app_profile.user_id

所以我做错了什么，只是看不出来。 无论如何，感谢您提供的任何帮助。
