Django 1.8 key 错误 : 'manager' on relationship

Question

我的模型设置如下:

class Post(models.Model):
    name = models.CharField(max_length=10)

class Comment(models.Model):
    post = models.ForeignKey(Post,related_name='comments')
    name = models.CharField(max_length=10)

当我想从帖子 somepost.comments() 获取所有评论时，我收到以下错误:

>> somepost.comments()
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "a_path/django/db/models/fields/related.py", line 693, in __call__
    manager = getattr(self.model, kwargs.pop('manager'))
KeyError: 'manager'

Answer 1

应该是somepost.comments.all()。

somepost.comments 返回一个查询集。 all 访问其中的对象。
