Python API端点返回TypeError:'；类型'；对象是不可编辑的,python,django,Python,Django,我正在编写一个createuserapi，通过使用AbstractBaseUser类扩展类users。对于常规的模型字段，比如EmailField，CharField，BooleanField，API运行良好。但后来我决定也存储用户的profile\u图片。因此，我创建了一个新字段profile\u picture作为ImageField，将用户的配置文件图片的路径存储在相同的扩展users模型中型号.py class Users(AbstractBaseUser, PermissionsMi

现在，当我尝试在http://127.0.0.1:8000/user/create/
它返回-
TypeError at /user/create/
'type' object is not iterable

parser\u classes=（FileUploadParser）

应该是
parser\u classes=（FileUploadParser，）

或者使用list[]
而不是tuple
如果不添加逗号，Python将以与x=something
相同的方式解释x=（something）
。
我只需要添加解析器类来解析请求。数据
parser_classes = (FormParser, MultiPartParser)

现在它返回{“detail”：“缺少文件名。请求应该包含一个带有文件名参数的内容处置头。”}
这是另一个错误。你问的那个问题已经解决了！请检查您能告诉我如何将请求传递到URLhttp://127.0.0.1:8000/user/create/
。我以前从未创建过图像上传API。我不知道如何发送JSON请求来上传文件。我是否必须提到图像文件的路径作为我的JSON对象中键
profile\u picture`的值？您可以使用表单通过request.FILES
获取内容。见：
