Django嵌套表单-始终显示对象而不是模型详细信息

我正在做一个通过夹层生成的Django项目。我已经能够创建我的模型，但是我希望有一个表单，管理员可以从列表中选择，以分配多对多或一对多关系中的值。例如，我有一个模式模型：

class Schema(AutoCreatedUpdatedMixin, SoftDeleteMixin):
    """List of all Schemas in a given database"""

    name = models.CharField(max_length=128, null=False)
    status = models.BooleanField(max_length=128, null=False, default=True, verbose_name="Is Active")
    description = models.CharField(max_length=65535, null=True, blank=True, default=None)
    database = models.ForeignKey(Database, on_delete=models.CASCADE)
    pull_requests = models.ManyToManyField(Link)
    questions = models.ManyToManyField(Question, blank=True)
    comments = models.ManyToManyField(Comment, blank=True)
    technical_owners = models.ManyToManyField(Employee, related_name='technical_owners_schemas', blank=True)
    business_owners = models.ManyToManyField(Employee, related_name='business_owners_schemas', blank=True)
    watchers = models.ManyToManyField(Employee, related_name='watchers_schemas', blank=True)

    def __unicode__(self):
        return "{}".format(self.name)

我有一个员工模型

class Employee(AutoCreatedUpdatedMixin, SoftDeleteMixin):
    """List of people with any involvement in tables or fields: business or technical owners, developers, etc"""

    name = models.CharField(max_length=256, blank=False, null=False, default=None, unique=True)
    email = models.EmailField(blank=True, null=True, unique=True)

    def __unicode__(self):
        return "{}".format(self.employee)

一个员工可以拥有多个架构，而一个架构可以由多个员工拥有。我的数据库中有一个活动的employee，但是当我尝试创建模式时，employee显示为employee对象。相反，我希望表单显示Employee.name。我该怎么做？我的管理文件包含以下内容：

class SchemasAdmin(admin.ModelAdmin):
    list_display = ['name', 'status', 'database', 'description']
    ordering = ['status', 'database', 'name']
    actions = []
    exclude = ('created_at', 'updated_at', 'deleted_at')

首先，您使用的是Python2还是Python3？对于3，应该使用_ustr__uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu。我写这篇文章是因为Employee的_uUnicode__;方法似乎有问题，尽管它被定义为：

def __unicode__(self):
    return "{}".format(self.employee)

th Employee类没有Employee属性，除非该类从AutoCreatedUpdatedMixin、SoftDeleteMixin继承的mixin中有这样一个属性，但我认为情况并非如此

在任何情况下，问题在于，如果在Employee类上使用python 3或python 2的unicode方法，您还没有定义propery\uuuuu str\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

return self.name

您应该在django admin select字段中看到员工的姓名
