Django image.save() TypeError: get_valid_name() missing positional argument: 'name'

Question

这是我试过的：

r = requests.get(img_url)
temp = NamedTemporaryFile(delete=True)
temp.write(r.content)
temp.flush()
image = Image()
image.image.save('testimagefilename', File(temp), save=True)
image.save()

在image.image.save()行，错误轨迹是：

Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/usr/local/lib64/python3.4/site-packages/django/db/models/fields/files.py", line 90, in save
    name = self.field.generate_filename(self.instance, name)
  File "/usr/local/lib64/python3.4/site-packages/django/db/models/fields/files.py", line 332, in generate_filename
    return os.path.join(self.get_directory_name(), self.get_filename(filename))
  File "/usr/local/lib64/python3.4/site-packages/django/db/models/fields/files.py", line 322, in get_filename
    return os.path.normpath(self.storage.get_valid_name(os.path.basename(filename)))
TypeError: get_valid_name() missing 1 required positional argument: 'name'

问题是因为 Django 需要本地 OS 路径吗？我正在使用 S3BotoStorage，ImageField 正在使用与项目其余部分不同的存储桶：

image = models.ImageField(storage=S3CustomStorage)

class S3CustomStorage(S3BotoStorage):
    def __init__(self, *args, **kwargs):
        kwargs['bucket'] = getattr(settings, 'AWS_BUCKET_CUSTOM')
        super(S3CustomStorage, self).__init__(*args, **kwargs)

Answer 1

也许会看到并更改

image = models.ImageField(storage=S3CustomStorage)

到

image = models.ImageField(storage=S3CustomStorage())

我遇到了相同的 TypeError ;-) 但现在它与我的情况下的附加 () 一起使用

Django image.save() TypeError: get_valid_name() missing positional argument: 'name'

Django image.save() TypeError: get_valid_name() missing positional argument: 'name'
