Question

当我在我的formset中输入信息时，图像会被删除，我无法前进到下一页。页面上没有错误。基本上，表单数据没有通过＆＃34; is_valid＆＃34;。我非常肯定我的view.py中有错误。

Models.py

class Testimonial(models.Model):
    author = models.ForeignKey(User, on_delete=models.CASCADE, default=None)
    image = VersatileImageField('image_testimonial', upload_to=upload_location, validators=[file_size], null=True, blank=True)
    message = models.CharField(max_length=300, default='', null=True, blank=True)
    name = models.CharField(max_length=100, default='', null=True, blank=True)
    city = models.CharField(max_length=100, default='', null=True, blank=True)
    state = models.CharField(max_length=100, default='', null=True, blank=True)

    def __str__(self):
        return self.author.username

forms.py

class TestimonialForm (forms.ModelForm):

    class Meta:
        model = Testimonial
        fields = ('image', 'message', 'name', 'city', 'state',)

views.py

@login_required(login_url="/accounts/login/") 
def testimonials(request):

TestimonialFormSet = modelformset_factory(Testimonial, form=TestimonialForm, extra=3)

if request.method == 'POST':

    formset = TestimonialFormSet(request.POST or None, request.FILES or None)

    if formset.is_valid():
        instances = formset.save(commit=False)
        for instance in instances:             #for instance in instances.cleaned_data:
            instance.author = request.user
            fix_orientation(instance.image)
            instance.save()

        return redirect('/accounts/profile/')

    else:                        
        args = {'formset': formset}
        return render(request, 'accounts/page6.html', args)
else:

    formset = TestimonialFormSet(queryset=Testimonial.objects.filter(author=request.user))

return render(request, 'accounts/page6.html', {'formset': formset})

Answer 1

我必须这样做 a）在我的模板中包含{{formset.errors}}以呈现阻止提交的错误

b）在模板中包含{{form.id}}，即使id不是我模型的一部分。这似乎是一个奇怪的形式怪癖，但唉，我现在可以提交表格了。
