Django表示“id可能不为NULL”但为什么呢? [英] Django says the "id may not be NULL" but why is it?
问题描述
class BlogPost(models.Model):
title = models.CharField(max_length = 100)
slug = models.SlugField(max_length = 100)
who = models.ForeignKey(User,default = 1)
when = models.DateTimeField()
介绍= models.TextField(blank = True,null = True)
content = models.TextField(blank = True,null = True)
counter = models.PositiveIntegerField(default = 0)
published = models.BooleanField(default = False)
css = models.TextField(blank = True,null = True)
class Meta:
订单=('-when','id')
模型下面有一些功能我也不会把它们全部包含在这里。他们的名字是: content_cache_key
, clear_cache
, __ unicode __
,读取
,读取
, processed_content
。
我正在通过管理员添加...我的头发不足。
我唯一可以想到的是,表模式已经从模型中脱离,因为有人从表的PK中删除了 AUTOINCREMENT
属性。
I'm going crazy today. I just tried to insert a new record and it threw back a "post_blogpost.id may not be NULL" error. Here's my model:
class BlogPost(models.Model):
title = models.CharField(max_length=100)
slug = models.SlugField(max_length=100)
who = models.ForeignKey(User, default=1)
when = models.DateTimeField()
intro = models.TextField(blank=True, null=True)
content = models.TextField(blank=True, null=True)
counter = models.PositiveIntegerField(default=0)
published = models.BooleanField(default=False)
css = models.TextField(blank=True, null=True)
class Meta:
ordering = ('-when', 'id')
There are a number of functions beneath the model too but I won't include them in full here. Their names are: content_cache_key
, clear_cache
, __unicode__
, reads
, read
, processed_content
.
I'm adding through the admin... And I'm running out of hair.
The only thing I can think of is that the table schema has become desynchronized from the model in that someone removed the AUTOINCREMENT
attribute from the PK of the table.
