“bytes”对象没有属性“_comfilled”

Question

我将创建多图像添加页面。但出现以下错误。你能帮我吗？我认为views.py中有错误。我不确定。

注意：Stackoverflow 要求提供很长的解释，这令人沮丧。

错误：

AttributeError at /en/projects/multiimageadd/10/

'bytes' object has no attribute '_committed'

@login_required
@permission_required('is_superuser')
def MultiImageAdd(request, id):
    blog = BlogModel.objects.filter(id=id).first()
    if request.method == 'POST':
        images = request.FILES['images']
        for image in images:
            Images.objects.create(project=project, image=image)
        return redirect("home")
    return render(request,"multiImage.html")

                </div>
            </div>
        </div>
    </div>

模型.py

class Images(models.Model):
    blog = models.ForeignKey(BlogModel, related_name='blogmodel', on_delete=models.CASCADE, blank=True,null=True)
    image = models.ImageField(blank=False, null=True)

Answer 1

您应该枚举文件处理程序，因此使用

.getlist(…)

 ^[Django-doc]:

获取处理程序

images = request.FILES.getlist('images')
for image in images:
    Images.objects.create(project=project, image=image)
