Question

我想上传任何文件。但是，当我提交上载时，同一帖子被上载了两次，但其中一个没有文件，只有内容，而下一个有文件。

class FileCreateView(PassRequestMixin, SuccessMessageMixin,
                 CreateView):
template_name = 'file/upload-file.html'
form_class = FileForm
success_message = 'File was uploaded successfully'
success_url = reverse_lazy('home')

def post(self, *args, **kwargs):
    """
    Handle POST requests: instantiate a form instance with the passed
    POST variables and then check if it's valid.
    """
    # form = self.get_form([self.request.FILES])
    form = self.form_class(self.request.POST, self.request.FILES)
    if self.request.method == 'POST':
        if form.is_valid():
            file = form.save(commit=False)
            file.upload = form.cleaned_data['upload']
            file.author = User.objects.get(pk=self.request.user.pk)
            file.save()
            return self.form_valid(form)
        else:
            return self.form_invalid(form)

home.html

  <div class="container mt-3">
    <div class="row">
      <div class="col-12 mb-3">
        <button class="upload-file btn btn-primary" type="button" name="button">
          <span class="fa fa-plus mr-2"></span>Upload Form</button>
      </div>
    </div>
{% block extrascripts %}
  <script type="text/javascript">
    $(function () {
     $(".upload-file").modalForm({formURL: "{% url 'file-upload' %}"});
   });
  </script>
{% endblock extrascripts %}

urls.py

 path('upload/file/', FileCreateView.as_view(), name="file-upload"),

model.py

class File(models.Model):
id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
author = models.ForeignKey(User, on_delete=models.CASCADE)
visible_to_home = models.ManyToManyField(Home, blank=True)  # when none visible to all home
visible_to_company = models.ManyToManyField(Company, blank=True)  # when none visible to all company
# To determine visibility, check if vtc is none or include company of user and if true, check same for home
created_date = models.DateTimeField(auto_now=True)
published = models.BooleanField(default=True)
upload = models.FileField(blank=True, null=True, upload_to=update_filename)
title = models.CharField(max_length=225, blank=True, null=True)
description = models.TextField(blank=True, null=True)

在上载的文件之一中，没有模型的upload字段，在下一个文件中，没有任何内容。
