TypeError: an integer is required (got type str) when running migrations or running tests
我修改了一个现有模型如下：
原来是这样
class AppAssessment(models.Model):
contact_uuid = models.CharField(max_length=255)
step = models.IntegerField(null=True)
optionId = models.IntegerField(null=True, blank=True)
user_input = models.TextField(null=True, blank=True)
title = models.TextField(null=True, blank=True)
description = models.TextField(null=True, blank=True)
created_at = models.DateTimeField(auto_now_add=True)
def __str__(self):
return (
f"UUID: {self.contact_uuid} | Step: {self.step} | OptionID: {self.optionId} \n"
f"| User_Input: {self.user_input} | Title: {self.title} \n"
f"| Created_at: {self.created_at}"
)
但是我把contact_uuid改成了contact_id并且改了模型类型：
class AppAssessment(models.Model):
contact_id = models.UUIDField()
step = models.IntegerField(null=True)
optionId = models.IntegerField(null=True, blank=True)
user_input = models.TextField(null=True, blank=True)
title = models.TextField(null=True, blank=True)
description = models.TextField(null=True, blank=True)
created_at = models.DateTimeField(auto_now_add=True)
def __str__(self):
return (
f"UUID: {self.contact_id} | Step: {self.step} | OptionID: {self.optionId} \n"
f"| User_Input: {self.user_input} | Title: {self.title} \n"
f"| Created_at: {self.created_at}"
)
在 views.py 中，我已经将条目存储为字符串
store_url_entry = AppAssessment(contact_uuid=contact_uuid, title=title, description=description, step=step, user_input=value, optionId=optionId)
store_url_entry.save()
我删除了数据库并重新创建了它，但它仍然失败。我也重新启动了虚拟环境，但它没有帮助。
我看到的错误是这样的：

感谢您的帮助。
我认为问题出在您的迁移文件中...这一行....
field = models.UUIDField(default=django.utils.timezone.now)
因为您正在尝试使用 timezone.now() 填充 UUID 字段。
因此，如果此迁移文件对您不重要，只需将其删除（如果此记录存在，您还需要从数据库中删除它的记录，即 django_migrations table）或者如果这只是一个测试环境中，您可以简单地从数据库中删除所有内容并执行 makemigrations 并再迁移一次（删除此迁移文件后 -> app.0021_auto_20220413_0328）。
重要说明：如果你想为你的 UUID 字段提供默认值，你应该使用类似的东西（在进行 makemigrations 和迁移之前）：
from uuid import uuid4
contact_id = models.UUIDField(default=uuid4)
因为你的 table 中有一些记录，而你正试图向它们添加没有默认值的 UUID 字段...然后 Django 将要求默认值，恐怕没有任何当 Django 询问类似以下内容时，在默认值中提供 uuid4() 的其他方法：
Please select a fix:
1) Provide a one-off default now (will be set on all existing rows with a null value for this column)
2) Quit, and let me add a default in models.py
另请注意，如果旧字段 (contact_uuid) 中的记录对您很重要，并且您想将其值添加到新字段 (contact_id)，您应该编写一个自定义迁移文件这是另一个故事。
