django - 如何正确定义 Django 管理站点的入口模型？

Question

from django.db import models

class Topic(models.Model):
    """A topic the user is learning about."""
    text = models.CharField(max_length=200)
    date_added = models.DateTimeField(auto_now_add=True) 

    def __str__(self):
        """Return a string representation of the model."""
        return self.text

class Entry(models.Model):
    """Something specific learned about a topic."""
    topic = models.ForeignKey(Topic, on_delete=models.CASCADE)
    text = models.TextField()
    date_added = models.DateTimeField(auto_now_add=True)
    
    class Meta:
        verbose_name_plural = 'entries'
 
    def __str__(self):
        """Return a string representation of the model."""
        return self.text[:50] + "..."

当我更新 models.py 时，makemigrations 命令返回了一个回溯。我还更新了添加 admin.site.register(Entry) 的 admin.py 文件。显示了相同的回溯，我一直被困在这个问题上。请帮助找到解决方案。
