Question

这是我的模特：

class News(models.Model):
  title = models.CharField(max_length=250)
  text = models.TextField()
  pub_date = models.DateTimeField(default=datetime.datetime.now)
  author = models.ForeignKey(User)

  def __unicode__(self):
    return self.title

我有一个简单的表格：

class NewsForm(ModelForm):
    class Meta:
            model = News
            exclude = ('pub_date','author',)

我排除pub_date，因为默认情况下是设置，而作者因为它是当前用户。但是如何将作者设置为当前登录用户？

我建议覆盖save()方法并将用户传递给它：

class NewsForm(ModelForm):

    def save(self, author, commit=True):
        # Don't commit the results yet
        news = ModelForm.save(self, commit=False)
        news.author = author
        if commit:
            news.save()
        return news

    class Meta:
            model = News
            exclude = ('pub_date','author',)

我需要在保存模型的实例时设置作者
