Question

我有以下模型：

class Article(TimestampedModel):
    title = models.CharField(max_length=255)
    slug = models.SlugField(db_index=True, max_length=255, unique=True, null=True, blank=True)
    introduction = models.TextField(null=True, blank=True)
    content = HTMLField('Content')
    image = models.ImageField(null=True, blank=True, upload_to='articles')

    parent = models.ForeignKey(
        'core.Article', on_delete=models.CASCADE, related_name='sectionparent', null=True, blank=True
    )
    authors = models.ManyToManyField(People, blank=True)
    active = models.BooleanField(default=True)
    SECTIONS = (
        ('about', 'About'),
        ('newsevents', 'News and Events'),
    )
    section = models.CharField(max_length=20, choices=SECTIONS, default='about')
    site = models.ForeignKey(Site, on_delete=models.CASCADE)
    objects = models.Manager()
    on_site = CurrentSiteManager()


class Event(models.Model):
    article = models.OneToOneField(
        Article,
        on_delete=models.CASCADE,
        related_name='event',
    ),
    EVENT_TYPE = (
        ('match', 'Match'),
        ('other', 'Other'),
    )
    start = models.DateTimeField(null=True, blank=True);
    end = models.DateTimeField(null=True, blank=True);
    type = models.CharField(max_length=20, choices=EVENT_TYPE)
    location = models.CharField(max_length=255, null=True, blank=True)
    url = models.CharField(max_length=255, null=True, blank=True)

但是，当我查看数据库中生成的事件表时，没有外键（我本来希望如此）。此外，我在文章中有记录：

article = Article.objects.find(1)

然后当我尝试访问该事件时：

event = article.event

我会收到此错误：

“文章”对象没有属性“事件”

OneToOne关系未链接
