Django：如何在不删除数据库的情况下将 cat_id 更改为 cat_slug？

如何解决Django：如何在不删除数据库的情况下将 cat_id 更改为 cat_slug？

sqlite 中的 Cat_id 现在是 int。有没有办法在不删除整个数据库的情况下将其更改为slug？我已经在将 men_id 更改为 slug 时删除了它，而且操作时间很长。

from django.db import models
from django.urls import reverse


class Men(models.Model):
    title = models.CharField(max_length=50,verbose_name='Заголовок')
    slug = models.SlugField(max_length=100,unique=True,db_index=True,verbose_name='URL')
    content = models.TextField(blank=True,verbose_name='Текст Статьи')
    photo = models.ImageField(upload_to="photos/%Y/%m/%d",verbose_name='Фото')
    time_create = models.DateTimeField(auto_Now_add=True,verbose_name='Время публикаци')
    time_update = models.DateTimeField(auto_Now=True,verbose_name='Время изменения')
    is_published = models.BooleanField(default=True,verbose_name='Видимость на сайте')
    cat = models.ForeignKey('Category',on_delete=models.PROTECT,verbose_name='Категория')

    def __str__(self):
        return self.title

    def get_absolute_url(self):
        return reverse('post',kwargs={'post_slug': self.slug})

    class Meta:
        verbose_name = 'Известного мужчину'
        verbose_name_plural = 'Известные мужчины'
        ordering = ['title']


class Category(models.Model):
    name = models.CharField(max_length=100,verbose_name='Название каатегории')
    slug = models.SlugField(max_length=100,verbose_name='URL')

    def __str__(self):
        return self.name

    def get_absolute_url(self):
        return reverse('category',kwargs={'cat_slug': self.slug})

    class Meta:
        verbose_name = 'Категорию'
        verbose_name_plural = 'Категории'
