python - 如何从两个具有相同型号名称的应用程序中删除对象？

Question

我有两个应用 news 和 article，它们的模型名称完全相同 Comment:

class Comment(models.Model):
    author = models.ForeignKey(User)
    created = models.DateTimeField(auto_now_add=True)
    title = models.CharField(max_length=100, default='', blank=True)
    body = models.TextField()
    post = models.ForeignKey(Photo)
    published = models.BooleanField(default=True)

现在，在一个 View 中，我想从两个应用程序中删除某些评论:

Comment.objects.filter(author=someauthor).delete()

如何在不更改模型名称的情况下实现这一目标？

Answer 1

您可以使用 import ... as ... 这样两个模型名称就不会冲突:

from news.models import Comment as NewsComment
from article.models import Comment as ArticleComment

...

NewsComment.objects.filter(author=someauthor).delete()
ArticleComment.objects.filter(author=someauthor).delete()
