Django DataError位于/ admin / posts / post / add /超出范围的整数

问题描述

在Django Admin中创建新帖子时出现整数超出范围错误。这是DRF项目，具有Post模型，该模型使用UUIDField作为主键作为id。似乎ID字段引起了问题，但我不明白UUIDField怎么可能超出范围。其余所有字段（如“标题”或“ URL”）都不能超出范围。

当我在管理控制台中创建新帖子时，单击“保存”按钮后出现以下错误消息：

DataError at /admin/posts/post/add/
integer out of range
Request Method: POST
Request URL:    http://localhost:8000/admin/posts/post/add/
Django Version: 3.0.7
Exception Type: DataError
Exception Value:    
integer out of range
Exception Location: /Users/username/Desktop/Workspace/project-api/venv/lib/python3.7/site-packages/django/db/backends/utils.py in _execute,line 86
Python Executable:  /Users/username/Desktop/Workspace/project-api/venv/bin/python
Python Version: 3.7.3

这是模型：

class UUIDModel(models.Model):
    id = models.UUIDField(primary_key=True,editable=False,default=uuid.uuid4)
    class Meta:
        abstract = True


class TimeStampedUUIDModel(UUIDModel):
    created_at = models.DateTimeField(auto_now_add=True,editable=False)
    modified_at = models.DateTimeField(auto_now=True,editable=False)
    class Meta:
        abstract = True

class Post(TimeStampedUUIDModel):
    creator = models.ForeignKey(User,on_delete=models.CASCADE,related_name="posts")
    title = models.CharField(
        _("Title"),max_length=255,blank=False,null=False)
    description = models.TextField(
        _("Description"),max_length=1500,null=False)
    url = models.URLField(_("URL"),unique=True,max_length=155,null=False)
    country = models.CharField(
        _("Country"),max_length=120,null=False)

    post_image = VersatileImageField(
        "Post image",null=False,upload_to=post_image_directory,ppoi_field="post_image_ppoi"
    )
    post_image_ppoi = PPOIField()

    STATUS_DRAFT = "D"
    STATUS_PUBLISHED = "P"
    STATUSES = (
        (STATUS_DRAFT,"Draft"),(STATUS_PUBLISHED,"Published"),)
    status = models.CharField(blank=False,choices=STATUSES,default=STATUS_DRAFT,max_length=2)
... ...

我查看了各种答案，但找不到整数超出范围问题的答案。跟踪显示以下消息：
