我在使用这个模型的时候，经常遇到多对多的问题，一开始我做的时候没有给id值，但是好像id值没有输入，所以直接输入id值的时候，出现了和上面一样的问题，但是在下面的Post模型中，使用了同样的点赞形式，为什么呢？

from django.db import models
# from django.contrib.auth.models import User

# from server.apps.user.models import Profile

class Clothes(models.Model):
  CATEGORYS =[
    (0, '상의'), #상의
    (1, '하의'), #하의
    (2, '아우터'), #아우터
    (3, '신발'), #신발
    (4, '악세사리'), #악세사리
  ]
  category = models.IntegerField(default=0,choices=CATEGORYS)
  id = models.IntegerField(primary_key=True)
  img = models.ImageField(upload_to='main/images/clothes/%Y/%m/%d')
  save = models.ManyToManyField(settings.AUTH_USER_MODEL, related_name='Pickitems', blank=True)
  author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
  buying = models.TextField(null=True, blank=True)
  
  def __str__(self):
    return f'{self.id}: {self.category}'
    #pk가 존재하지 않는것 같음. 

# class SavePeople(models.Model):
  

class Post(models.Model):
  main_img = models.ImageField(upload_to='main/images/post/%Y/%m/%d')
  title = models.CharField(max_length=100)

  author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
  content = models.TextField()
  create_date = models.DateTimeField(auto_now_add=True)
  update_date = models.DateTimeField(auto_now_add=True)
  
  def __str__(self):
    return f'({self.author}) {self.post.title} :  {self.content}'
  
class Commu(models.Model):
  COMMU_CHOICES = [
    ('buying', 'buying'), #공동구매
    ('openrun', 'openrun'), #오픈런
    ('question', 'question'), #고민방
  ]
  category = models.CharField(max_length=20, choices=COMMU_CHOICES)
  img = models.ImageField(upload_to='main/images/commu/%Y/%m/%d', null=True, blank=True)
  title = models.CharField(max_length=100)
  content = models.TextField()
  author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
  
  def __str__(self):
    return f'{self.pk}: {self.title}'
  
  def get_absolute_url(self):
    return f'/community/commu'

我把代码saves= models.ManyToManyField(settings.AUTH_USER_MODEL, related_name='Save', blank=True)添加到衣服模型中，像Post模型一样保存衣服，但是出现了如附件图片所示的错误，搜索时，pk值似乎不存在。
