I wanted to upload any file. But when I submit the upload then same post is uploaded twice but in one of it there is no file but just the content and in next there is file.

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)

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)

In one of the uploaded file there is no upload field of the model and the next of the twice there is everything.
