我需要列出每个员工的工作时间,但我得到:

模型“”具有空属性“work\u Travely”,不允许空值。

关于:

/rest/tastype/employee/?format=json

models.py

class Employee():
    registration = models.CharField(u'Registration', max_length=20, unique=True)
    work_journey = models.ForeignKey(WorkJourney, null=True, blank=True)
hr.models.py

class WorkJourney(ModelPlus):
    code = models.CharField(max_length=10, null=True, unique=True)
    workinghours = models.CharField(max_length=40)
    excluded = models.BooleanField()

    class Meta:
        db_table='work_journey'
        verbose_name = u'Work Journey'

    def __unicode__(self):
        return self.workinghours
资源.py

from suap.models import Employee
from hr.models import WorkJourney


class WorkJourneyResource(ModelResource):
    class Meta:
        queryset = WorkJourney.objects.all()
        resource_name = 'work_journey'
        authentication = BasicAuthentication()

class EmployeeResource(ModelResource):
    journey = fields.ForeignKey(WorkJourney, 'work_journey')
    class Meta:
        queryset = Employee.objects.all()
        resource_name = 'employee'
        authentication = BasicAuthentication()

1/当您在ressoure.py中定义关系时,您需要一个
工作行程资源
而不是
工作行程

2/要允许空值,只需添加
null=True,blank=True

以下是修复代码:

class EmployeeResource(ModelResource):
    journey = fields.ForeignKey(WorkJourneyResource, 'work_journey', null=True, blank=True)
    ....

我的WorkJourneyResource不好,我的代码还可以。在添加null=True、blank=True时,它可以工作。但是它只是从工作之旅返回资源uri。这是一种正常的行为。在您的字段中添加
full=True
