Django Rest Framework如何发布日期字段 [英] Django Rest Framework how to post date field
问题描述
我要发布带有字段 date
的JSON请求:
I want to post JSON request with field date
:
{
"date":"2015-02-11T00:00:00.000Z"
}
这是从 Date
对象自动转换的字符串,我不想裁剪 T00:00:00.000Z
在前端手动进行。
It's the string is automatically converted from Date
object and I don't want to crop the part T00:00:00.000Z
manually at frontend.
但是,如果我发布了这样的请求,则DateField的Django Rest Framework验证程序会说我该日期的格式无效。
But if I post such request, Django Rest Framework validator of DateField will say me, that date has invalid format.
我的模型:
class Event(models.Model):
name = models.CharField('Name', max_length=40, blank=True, null=True)
date = models.DateField('Date', blank=True, null=True)
我的序列化器:
class EventSerializer(serializers.ModelSerializer):
class Meta:
model = Event
fields = ('id', 'name', 'date')
解决此问题的正确方法是什么?
What is the right way to solve this problem?
推荐答案
您可以使用不同的格式(不同于隐式使用的默认格式)修改序列化程序中的日期字段。
You can modify your date field in your serializer with a different format (different from the default one, which you are using implicitly).
更多信息:
https://www.django-rest-framework.org/api-guide/fields/#datefield
https://docs.python.org/3/ library / datetime.html#strftime-and-strptime-behavior
from rest_framework import serializers, fields
class EventSerializer(serializers.ModelSerializer):
date = fields.DateField(input_formats=['%Y-%m-%dT%H:%M:%S.%fZ'])
class Meta:
model = Event
fields = ('id', 'name', 'date')
请注意,如果您需要解析除在UTC(时间戳末尾为Z)中,您将需要更多自定义 DateField
。
Note that if you need to parse timestamps other than in UTC (Z at the end of your timestamp), you will need to customize DateField
a bit more.
正如注释中提到的@nitrovatter一样,日期输入格式也可以在设置中配置为默认情况下影响每个序列化程序。例如:
As @nitrovatter mentioned in the comments, the date input formats can also be configured in the settings to affect every serializer by default. For example:
REST_FRAMEWORK = {
'DATE_INPUT_FORMATS': ['iso-8601', '%Y-%m-%dT%H:%M:%S.%fZ'],
}
