Django图像上传 - 图像文件不保存

Question

我正在编写一个项目，您可以从磁盘或其他网站向网站添加照片。在jquery中，我写了一本书标记，我可以在其中添加其他网站的图片。但是我从光盘上传图像时遇到问题。我写了模型，模型，视图和html文件。当我在表单中选择一个img文件时，看起来都很好。我已移至图片列表网页，但没有文件我要上传的内容。图像文件未保存。我不知道自己做错了什么。以下是我的代码：

models.py

class Image(models.Model):
user = models.ForeignKey(settings.AUTH_USER_MODEL,
                         related_name='images_created')
title = models.CharField(max_length=200)
slug = models.SlugField(max_length=200,
                        blank=True)
url = models.URLField(blank=True)
image = models.ImageField(upload_to='images/%Y/%m/%d')
description = models.TextField(blank=True)
created = models.DateField(auto_now_add=True,
                           db_index=True)
users_like = models.ManyToManyField(settings.AUTH_USER_MODEL,
                                related_name='images_liked',
                                blank=True)

total_likes = models.PositiveIntegerField(db_index=True, default=0)


def __str__(self):
    return self.title

def save(self, *args, **kwargs):
    if not self.slug:
        self.slug = slugify(self.title)
    super(Image, self).save(*args, **kwargs)

def get_absolute_url(self):
    return reverse('images:detail', args=[self.id, self.slug])

class Meta:
    ordering = ["-image"]

forms.py

class ImageCreateForm(forms.ModelForm):
class Meta:
    model = Image
    fields = ('title', 'url', 'description')
    widgets = {
        'url': forms.HiddenInput,
    }

def clean_url(self):
    url = self.cleaned_data['url']
    valid_extensions = ['jpg', 'jpeg']
    extension = url.rsplit('.', 1)[1].lower()
    if extension not in valid_extensions:
        raise forms.ValidationError('Podany adres URL nie zawiera ' \
                                    'obrazów w obsługiwanym formacie.')
    return url

def save(self, force_insert=False,
               force_update=False,
               commit=True):
    image = super(ImageCreateForm, self).save(commit=False)
    image_url = self.cleaned_data['url']
    image_name = '{}.{}'.format(slugify(image.title),
                                image_url.rsplit('.', 1)[1].lower())

    # Pobranie pliku obrazu z podanego adresu URL.
    response = request.urlopen(image_url)
    image.image.save(image_name,
                     ContentFile(response.read()),
                     save=False)
    if commit:
        image.save()
    return image

    <form action="." method="post" enctype="multipart/form-data">
        {{ upload_form.as_p }}
