Question

在models.py中为雇主提供的我的雇主代码：

class Employee(Person):

    """
    Employee details and their rights to portal.
    """
    name = models.CharField(max_length=50, db_index=True, blank=True)
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    e_id = models.CharField(max_length=20, db_index=True, unique=True)
    student_permit = models.BooleanField(default=False)
    company_permit = models.BooleanField(default=False)
    placement_permit = models.BooleanField(default=False)

    def __str__(self):
        return str(self.e_id + '-' + self.name)

    def __unicode__(self):
        return unicode(self.e_id + '-' + self.name)

我在context_py函数中的雇主代码：

def get_emp_info(Employee):        
    blood_groups = blood_group_helper()
    genders = gender_helper()
    info = {
        'ename': Employee.name,
        'dob': Employee.dob,
        'gender': [i for i in genders if Employee.gender in i],
        'phone': Employee.phone,
        'address': Employee.curr_address,
        'emp_id': Employee.e_id,
        'bgroup': [i for i in blood_groups if Employee.blood_group in i],
        'photo': os.path.join(settings.MEDIA_URL, employee.photo.name) if Employee.photo else None,
    }
    return info

错误提示：

文件 “ C：\ Users \ Administrator \ placement \ placement \ helpers \ context_helper.py”，第109行，位于get_emp_info中 'ename'：Employee.name，AttributeError：'NoneType'对象没有属性'name'

这是什么错误？这个错误的解决方案是什么？

AttributeError：'NoneType'对象在Employee中没有属性'name'
