Question

这就是我的尝试：

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()行上，错误跟踪为：

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期待本地操作系统路径吗？我正在使用S3BotoStorage，ImageField正在使用项目其余部分的独立存储桶：

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

也许请参阅Trying to understand Django source code and cause of missing argument TypeError并更改

image = models.ImageField(storage=S3CustomStorage)

到

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

我有相同的TypeError ;-)但现在它适用于我的情况下的additional（）

Django image.save（）TypeError：get_valid_name（）缺少位置参数：'name'
