Python 列表显示不'；行不通

在

models.py中有一个名为
Employees
的类

class Employees(models.Model):
    employee_id = models.CharField(verbose_name = _("Employee ID"), max_length=20, primary_key=True)
    employee_name = models.CharField(verbose_name = _("Employee Name"), max_length=20)
    department = models.CharField(verbose_name = _("Department"), max_length=100)
    post = models.CharField(verbose_name = _("Post"), max_length=100)

class EmployeesAdmin(admin.ModelAdmin):
    list_display = ('employee_id', 'employee_name', 'department', 'post')

然后我在
admin.py

class Employees(models.Model):
    employee_id = models.CharField(verbose_name = _("Employee ID"), max_length=20, primary_key=True)
    employee_name = models.CharField(verbose_name = _("Employee Name"), max_length=20)
    department = models.CharField(verbose_name = _("Department"), max_length=100)
    post = models.CharField(verbose_name = _("Post"), max_length=100)

class EmployeesAdmin(admin.ModelAdmin):
    list_display = ('employee_id', 'employee_name', 'department', 'post')

根据教程，Employee分支中应该有四个字段。但在我的情况下，只有一个字段名为
Employees
，就像我没有在
admin.py
中添加
EmployeesAdmin
类一样。怎么了？我错过什么了吗


admin.py:

from django.contrib import admin
from .models import Employees, Purchase, ProductsOut

# Register your models here.
admin.site.register(Employees)
admin.site.register(Purchase)
admin.site.register(ProductsOut)

在admin.py中声明
EmployeesAdmin
类后，请尝试以下操作：

admin.site.register(Employees, EmployeesAdmin)

在admin.site中注册您的管理员，如：-

admin.site.register(ModelName, AdminName)

你能给我们看看你的
admin.py
？@Michael，更新了，我还有两个类是用
models.py
文件编写的，但我认为这不是问题。
