【问题描述】：
有一个愚蠢的问题：当我打开员工模型（在 django admin 中）时，一个字段 (employee_type) 值被自动替换，我知道为什么... 示例：我创建员工，将员工类型定义为经理，保存。在 DB 中，值是经理。之后，我打开员工并看到员工类型为下水道，如果我保存，该值将保存在数据库中。
我为此字段创建了文本选择，并且在 DB 字段中定义为枚举。 我试图研究这个问题，没有使用 DB 中的值，总是使用文本选择中的第一个值。
顺便说一句，我在其他模型中创建了相同的字段（数据库中的枚举和模型中的文本选择）。一切正常。
我该如何解决？？？
Models.py 有问题：
class Employee(models.Model):
class EmployeeType(models.TextChoices):
SEWER = 'SEWER', _('Sewer')
MANAGER = 'MANAGER', _('Manager')
UNDEFINED = 'UNDEFINED', _('Undefined')
user = models.OneToOneField(User,
models.CASCADE,
db_column='user',
verbose_name=_('User'),
primary_key=True)
employee_type = models.CharField(db_column='Employee type',
verbose_name=_('Employee type'),
max_length=9,
choices=EmployeeType.choices,
default=EmployeeType.UNDEFINED)
phone = models.CharField(db_column='Phone',
verbose_name=_('Phone'),
max_length=255)
work_xp = models.IntegerField(db_column='Work XP',
verbose_name=_('Work XP'),
blank=True,
null=True)
另一个models.py。具有相同的字段但没有问题：
class Order(models.Model):
class OrderStatus(models.TextChoices):
CREATED = 'Created', _('Created')
CANCELLED = 'Cancelled', _('Cancelled')
IN_PROGRESS = 'In progress', _('In progress')
COMPLETED = 'Completed', _('Completed')
PASSED_TO_CLIENT = 'Passed to the client', _('Passed to the client')
RETURNED_FOR_REWORK = 'Returned for rework', _('Returned for rework')
class Urgency(models.TextChoices):
LOW = 'Low', _('Low urgency')
MEDIUM = 'Medium', _('Medium urgency')
HIGH = 'High', _('High urgency')
VERY_HIGH = 'Very high', _('Very high urgency')
class LabourIntensity(models.TextChoices):
LOW = 'Low', _('1-3 days')
MEDIUM = 'Medium', _('4-6 days')
HIGH = 'High', _('7-9 days')
VERY_HIGH = 'Very high', _('10+ days')
class PaymentStatus(models.TextChoices):
PENDING = 'Pending payment', _('Pending payment')
PREPAYMENT_MADE = 'Prepayment made', _('Prepayment made')
PAID = 'Paid', _('Paid')
id_service = models.ForeignKey(Service,
models.SET_NULL,
db_column='id_Service',
verbose_name=_('Service'),
blank=True,
null=True)
status = models.CharField(db_column='Status',
verbose_name=_('Status'),
max_length=20,
choices=OrderStatus.choices,
default=OrderStatus.CREATED)
payment_status = models.CharField(db_column='Payment status',
verbose_name=_('Payment status'),
max_length=15,
choices=PaymentStatus.choices,
blank=True,
null=True)
prepayment = models.DecimalField(db_column='Prepayment',
verbose_name=_('Prepayment'),
max_digits=19,
decimal_places=2,
blank=True,
null=True)
cost = models.DecimalField(db_column='Cost',
verbose_name=_('Cost'),
max_digits=19,
decimal_places=2,
blank=True,
null=True)
start_date = models.DateTimeField(db_column='Start date',
verbose_name=_('Start date'),
blank=True,
null=True)
end_date = models.DateTimeField(db_column='End date',
verbose_name=_('End date'),
blank=True,
null=True)
id_client = models.ForeignKey(Client,
models.SET_NULL,
db_column='id_Client',
verbose_name=_('Client'),
blank=True,
null=True)
id_employee = models.ForeignKey(Employee,
models.SET_NULL,
db_column='id_Employee',
verbose_name=_('Employee'),
blank=True,
null=True)
labour_intensity = models.CharField(db_column='Labour intensity',
verbose_name=_('Labour intensity'),
max_length=9,
choices=LabourIntensity.choices,
default=LabourIntensity.LOW)
urgency = models.CharField(db_column='Urgency',
verbose_name=_('Urgency'),
max_length=9,
choices=Urgency.choices,
default=Urgency.LOW)
materials = models.ManyToManyField(Material, through='OrderMaterials')
comment = models.TextField(db_column='Comment',
verbose_name=_('Comment'),
blank=True,
null=True)
【问题讨论】：
-
为什么employee_type的选择使用LabourIntensity，而不是EmployeeType？

@TimNyborg 我尝试通过这种方式进行调试，但在发布之前忘记返回初始代码。现在已经修复了
