我尝试在Django中上传图像，但我不能。我不知道有什么问题。
错误：

django.core.exceptions.SuspiciousFileOperation:

Upload型号：

我试着将路径设置为BASE_DIR/self.path/filename，但没有任何不同。
我的settings.py：

STATIC_URL = '/static/'
STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'static')
]
if not DEBUG:
    STATIC_ROOT = os.path.join(BASE_DIR, 'static')

MEDIA_URL = '/media/'
if not DEBUG:
    MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
