Django models 如何在django中通过uuid4获取正确的UUID格式而不获取连字符？,django-models,django-forms,uuid,Django Models,Django Forms,Uuid,我是新手，我正在尝试将uuid保存到我的模型中 正如所研究的，uuid的正确格式是- UUID表示为32个十六进制（以16为基数）数字，以8-4-4-4-12的形式分五组显示，共36个字符（32个十六进制字符和4个连字符）。例如：123e4567-e89b-12d3-a456-426614174000 但当我保存表单时，它会将我的UUID呈现为字符串 0262d1dae7334d44b97b96f2915719ec 我的模特是- class registertable(models.Model)

我是新手，我正在尝试将uuid保存到我的模型中

正如所研究的，uuid的正确格式是- UUID表示为32个十六进制（以16为基数）数字，以8-4-4-4-12的形式分五组显示，共36个字符（32个十六进制字符和4个连字符）。例如：123e4567-e89b-12d3-a456-426614174000

但当我保存表单时，它会将我的UUID呈现为字符串
0262d1dae7334d44b97b96f2915719ec

我的模特是-

class registertable(models.Model):
    registeri=models.UUIDField(primary_key=True, default=uuid.uuid4,editable=False,unique=True)
    date_of_collection=models.DateField()
请帮忙，因为当我用它来保存和更新表单时，它会给我以下错误- ['“”不是有效的UUID。“]

它表示空字符串不是有效的uuid，因此问题可能是表单无法工作。您可以共享引发此错误的视图和模板吗？@WillemVanOnsem hey请检查edits0262d1dae7334d44b97b96f2915719ec此id已从数据库复制，因此我们可以说这正在生成uuid
