在my views.py文件中使用

the client.

valid_ser = ValidateNewCoopSerializer(data=request.data)
if valid_ser.is_valid():

...
return Response(post_data, status=status.HTTP_201_CREATED)
else:
return Response(valid_ser.errors, status=status.HTTP_400_BAD_REQUEST)
不过,我注意到,当我提交请求时,字段被标记为非必需,但返回时会出现错误

导致

如何配置序列化程序,使这些字段实际上不是必需的?您已在序列化程序字段上设置了
required=False
。这意味着,如果您在请求中没有为他们提供密钥,它将起作用,,但是如果您提供了密钥,那么他们将被验证。查看您的请求,您传递了“desc_english”:“
,即,您确实为密钥提供了一个空字符串,因此该错误是正确的。如果要允许空字符串,可以在字段上设置:
desc_english=serializers.CharField(required=False, allow_blank=True)
如果希望将空值(None
在python中)传递给字段,也可以设置为True
:
desc_english=serializers.CharField(required=False, allow_blank=True, allow_null=True)
谢谢我觉得“required=false”应该表示根本没有验证检查,但我猜“required”对不同的人意味着不同的东西。
