AWS s3bucket“只能将str（不是“NoneType”）连接到str”

Question

我无法找出问题所在。如果它的 boto3 或 s3bucket ， DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' 似乎是问题，我不知道是什么导致了错误。至少当我删除 DEFAULT_FILE_STORAGE 模板呈现。 我要么得到'NoneType' 对象没有属性'encode' 和'ImageFieldFile' 对象是不可下标的'我的仪表板视图或 "只能将 str (不是 "NoneType") 连接到 str" 尝试上传图片。

Answer 1

我想通了，显然我应该使用 AWS_S3_SECRET_ACCESS_KEY 和 AWS_S3_ACCESS_KEY_ID。
