Question

输出看起来像这样（项目名为parkingtickets）：

usr/local/webapps/parkingtickets/django_project$ python manage.py syncdb
Creating tables ...
Creating table parkingtickets_correction

然后永远挂起。如果我暂停这个过程并杀死它，它就不会死;我必须使用kill -9。我以前从未遇到过这种情况 - 截至今天早上我的应用程序运行顺利。我上次成功运行了syncdb 3天前。那时我已经定义了修正，并且工作正常。我修改了模型以包含一个新字段 - 一个允许为空的不可编辑外键 - 删除表，然后点击syncdb。现在这个。我很乐意发布人们认为必要的任何信息。相关的settings.py（CRUD是我们开发的一个内部框架，主要为我们加载通用模板）：

编辑：好的，所以我添加的新外键会导致问题。任何其他表的外键工作正常，对外键的修改不会改变任何东西（例如，上下移动它以便在不同时间解析它，使其可编辑，使其不接受空值）。这是我想要外键进入的表的定义，Ticket：

class Ticket(CrudModel):
    _amount_due = models.DecimalField(decimal_places=2,max_digits=32,default=Decimal('0.00'),editable=False)
    _amount_paid = models.DecimalField(decimal_places=2,max_digits=32,default=Decimal('0.00'),editable=False)
    number = models.CharField(max_length=128,unique=True)
    ticket_date = models.DateField()
    time = models.TimeField()
    plate_number = models.CharField(max_length=128)
    plate_state = USStateField(default='CT')
    make = models.ForeignKey(Make)
    model = models.CharField(max_length=128)
    color = models.ForeignKey(Color)
    location = models.CharField(max_length=128)
    officer = models.ForeignKey(Officer)
    _class = models.ForeignKey(Class,null=True,blank=True,verbose_name='Class')
    vin = models.CharField(max_length=128,blank=True)
    towed_to = models.CharField(max_length=128,blank=True)
    remarks = models.TextField(blank=True)
    owner = models.ForeignKey(Owner,null=True,blank=True)
    delinquency_letter = models.DateField(null=True,blank=True)

Django：python manage.py syncdb永远挂起
