[英]Django rest api expected string or buffer on PATCH
I'm making a Django application, where I am sending requests through rest API. 我正在制作Django应用程序,在这里我通过rest API发送请求。 I am using POST and GET and all works pretty well, but when I am trying to use PATCH (as I must firstly upload field "start_time", and then add field "time"), I'm getting following error:
我正在使用POST和GET,并且一切正常,但是当我尝试使用PATCH时(因为我必须首先上载字段“ start_time”,然后添加字段“ time”),出现以下错误:
match = time_re.match(value) TypeError: expected string or buffer match = time_re.match(value)TypeError:预期的字符串或缓冲区
Surely it is about views.py, but I cannot find clear recipe how to do that, thus I don't know where I am wrong. 当然,这是关于views.py的问题,但是我找不到明确的方法来做到这一点,因此我不知道我哪里做错了。
Thank you. 谢谢。
Views.py Views.py
...
elif request.method = 'PATCH':
serializer = TABLESerializer(data=request.data, partial=True)
if serializer.is_valid():
obj = TABLE.objects.get(start_time=request.data['start_time'])
obj.time = serializer['time']
obj.save()
return Response(serializer.data, status=status.HTTP_201_CREATED)
return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
Serializers.py Serializers.py
class TABLESerilizer(serializers.serializer):
start_time = serializers.DateTimeField(format = None, allow_null=True)
time = serializers.TimeField(format=None, required=False)
models.py models.py
class TABLE(models.Model):
start_time=models.DateTimeField(primary_key=True)
time = models.TimeField(null= True, blank= True, default = '00:00:00')
format - A string representing the output format.
format-代表输出格式的字符串。 If not specified, this defaults to the same value as the TIME_FORMAT settings key, which will be 'iso-8601' unless set.
如果未指定,则默认为与TIME_FORMAT设置键相同的值,除非设置,否则为'iso-8601'。
But in your case you set it to None
. 但是根据您的情况,将其设置为
None
。 we get error when python try to parse the data into time object with format None
format must me like HH:MM:SS
, etc. 当python尝试将数据解析为格式为
None
时间对象时,我们会收到错误消息,格式必须为HH:MM:SS
,等等。
update your serializer like below 如下更新您的序列化器
from rest_framework.settings import api_settings
class TABLESerilizer(serializers.serializer):
start_time = serializers.DateTimeField(format=api_settings.TIME_FORMAT)
time = serializers.TimeField(format=api_settings.TIME_FORMAT)
