＆＃39; NoneType＆＃39;对象没有属性＆＃39; __ getitem __＆＃39;

标签： python django amazon-s3 sorl-thumbnail

在尝试访问管理员面板中的用户个人资料时，我开始遇到此问题。

TypeError at /admin/users/userprofile/2/
'NoneType' object has no attribute '__getitem__'

在我的应用程序中集成Django Storages以使用Amazon S3存储服务之后，它才开始发生。我无法弄清楚这里有什么冲突。回溯似乎表明问题在于我用于我的用户图像字段的sorl thubmnails。

这是我的settings.py 

DEFAULT_FILE_STORAGE = 'storages.backends.s3boto.S3BotoStorage'
STATICFILES_STORAGE = 'storages.backends.s3boto.S3BotoStorage'

AWS_ACCESS_KEY_ID = 'my-access-key'
AWS_SECRET_ACCESS_KEY = 'my-secret-key'
AWS_STORAGE_BUCKET_NAME = 'my-bucket-name'

STATIC_URL = 'http://' + AWS_STORAGE_BUCKET_NAME + '.s3.amazonaws.com/'
ADMIN_MEDIA_PREFIX = STATIC_URL + 'admin/'

这是我的用户模型

from sorl.thumbnail import ImageField

class UserProfile(AbstractBaseUser):
    email = models.EmailField(max_length=255, unique=True)
    username = models.CharField(max_length=100, unique=True)
    name = models.CharField(max_length=255)
    location = models.CharField(max_length=255, blank=True, null=True)
    website = models.CharField(max_length=255, blank=True, null=True)
    image = ImageField(upload_to='media', blank=True, null=True)
    points = models.PositiveIntegerField(default=0)
    added_on = models.DateTimeField(auto_now_add=True)

    is_active = models.BooleanField(default=True)
    is_admin = models.BooleanField(default=False)

以下是问题的追溯

错误是由图像属性的缺失图像文件引起的。检查用户的UserProfile.image的文件路径（ID = 2）。

可能是您将代码和数据库从一个位置复制到另一个位置，但您没有复制关联的图像文件。
