Question

我正在尝试创建一个文档表单，并将文档位置写入用户当前的数据库条目中，当我尝试这样做时，它会不断创建一个新条目，就像我试图在该部分中使用pk = p一样写入数据将覆盖整个条目。

views.py

** I import everything here **

@login_required(login_url='/accounts/login/')
def list(request):
# Handle file upload
if request.method == 'POST':
    form = DocumentForm(request.POST, request.FILES)
    if form.is_valid():
        p = request.user.pk
        newdoc = CustomUser.objects.get(pk=p)
        newdoc = CustomUser(docfile = request.FILES['docfile'])
        # I also attempted the following which overwrit the entire user
        # newdoc = CustomUser(pk=p, docfile = request.FILES['docfile']))
        newdoc.save()

        # Redirect to the document list after POST
        return HttpResponseRedirect(reverse('list'))
else:
    form = DocumentForm() # A empty, unbound form

current_user = request.user

# Render list page with the documents and the form
return render(request, 'list.html', {'form': form,'pk':current_user.pk})

为用户

models.py

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

class CustomUser(AbstractUser):
 pass

 def __str__(self):
     return self.email

 docfile = models.FileField(upload_to='static/users/',)

forms.py

from django import forms

class DocumentForm(forms.Form):
    docfile = forms.FileField(
        label='Select a file',
        help_text='max. 42 megabytes'
)

写入当前条目而不是在Django中创建一个新条目
