在Django中上传多个图像

Question

我有两个模型和两个不同的形式。拖曳形式组合在单个视图功能中。这两种形式组合在一个HTML形式中。当我提交HTML表单时，除未保存图像外，其他一切都正常。 这是拖车模型：

class Posts(models.Model):
    user = models.ForeignKey(MyUser, on_delete=models.CASCADE)
    post_category = models.ForeignKey(Post_Category, 
    on_delete=models.CASCADE)

    post_title = models.CharField(max_length=256)
    post_detail = models.TextField(max_length=65536)

    def __str__(self):
        return "%s %s %s %s " % (
            self.user, self.post_category, self.post_title, 
            self.post_detail)

    class Meta:
        verbose_name_plural = "Posts"


class Images(models.Model):
    post = models.ForeignKey(Posts, on_delete=models.CASCADE)
    images = models.ImageField(upload_to='images', blank=True, null=True )


    def __str__(self):
        return "%s %s" % (self.post, self.images)

    class Meta:
            verbose_name_plural = "images"

这些形式是：

class PostsForm(forms.ModelForm):


class Meta:
    model = Posts

    fields = [
            'post_category', 
            'post_title', 'post_detail', 

        ]

class ImagesForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        kwargs.setdefault('label_suffix', '')
        super(ImagesForm , self).__init__(*args, **kwargs)


        self.fields['car_images'].widget.attrs.update({'class' : 'image',
            'style':'display:none','id':'input-image-hidden',
            'onchange':"document.getElementById('image-preview').src = window.URL.createObjectURL(this.files[0])" ,
            'type':'file', "name":"images", 'accept':'image/*'})

    class Meta:
        model = Images

        fields = [
            'images',
        ]


        widgets = {

            'images': forms.ClearableFileInput(attrs={'multiple': True}),
        }

这是查看功能：

from django.forms import inlineformset_factory
from django.utils.translation import ugettext_lazy as _

def post(request):
    form = PostsForm()
    imagesForm = ImagesForm()

    template_name = 'path/to/template.html'

    success_url = 'user_profile.html'

    form = PostsForm(request.POST or None)
    imagesForm = ImagesForm(request.POST or None, 
    request.FILES or None)

    if form.is_valid() and imagesForm.is_valid():
        new_post = form.save(commit=False)
        new_post.user = request.user 


        new_post = form.save()


        imagesForm.save(commit=False)

        for file in request.FILES.getlist('images'):

            instance = Images(
            post= Posts.objects.get("images"),
            images=file
        )

            instance.save()
        return redirect('index')

    else:
        imagesForm = ImagesForm(request.POST or None, request.FILES or 
None)
    return render(request, template_name, {'imagesForm': imagesForm, 
'form': form})

提交HTML表单时，将保存除图像外的所有数据（不会出现错误）。将再次显示HTML表单，而不是重定向到用户个人资料页面。 您能告诉我发生了什么以及可能的错误在哪里吗？您能帮我保存多张图片吗

注意：如果必须设置额外的参数，则无法使用内联表单集工厂。我不想限制用户上传数量有限的图像。
