Django Rest框架的关键错误
我正在用DjangoRestFrameowork构建一个RESTful API，在我的模型中尝试使用Django Rest框架的关键错误,django,django-rest-framework,serialization,Django,Django Rest Framework,Serialization,我正在用DjangoRestFrameowork构建一个RESTful API，在我的模型中尝试使用选项时遇到了一个错误。当访问api端点时，我在/jobs/u'job\u type'处得到错误KeyError。我的模特有 JOB_CHOICES = ( ('p', 'Paint'), ('pw', 'Pressure Wash'), ('h', 'Hourly'), ) class Job(models.Model): created = models.Dat
选项时遇到了一个错误。当访问api端点时，我在/jobs/u'job\u type'KeyError。我的模特有
JOB_CHOICES = (
('p', 'Paint'),
('pw', 'Pressure Wash'),
('h', 'Hourly'),
)
class Job(models.Model):
created = models.DateTimeField(auto_now_add=True)
budget = models.IntegerField()
job_type = models.CharField(choices=JOB_CHOICES,
default='p',
max_length=100)
我的序列化程序如下所示：
class JobSerializer(serializers.ModelSerializer):
class Meta:
model = Job
fields = ('pk',
'budget',
'created',
'job_type',)
我不知道这是怎么回事。他们在Django Rest框架教程中做了类似的事情，我不知道我的有什么不同。任何帮助都将不胜感激

元类应该是序列化程序的内部类，而不是单独的类。试试这个：
class JobSerializer(serializers.ModelSerializer):
class Meta:
model = Job
fields = ('pk',
'budget',
'created',
'job_type',
)
什么时候发生？当你发布或获取时？当我获取时，我没有尝试发布Yet。看起来你的一个对象有一个job\u type
值为“job\u type”，这不是一个有效的选择。还有一张关于它的DRF票还在开着。你是说这可能是一个bug？有解决方法吗？@bencunningham你可以通过在你的工作选择中添加另一个元素来测试Kevin的理论，
（“工作类型”，“坏数据”），
