我有Blog模型,Post模型和Comment模型:

class Blog(models.Model):

    title = models.CharField(_('name'), max_length=80)        
    creator = models.ForeignKey(User, related_name="created_pages")
    created = models.DateTimeField(_('created'), default=datetime.now)
    description = models.TextField(_('description'), null=True, blank=True)

class Post(models.Model):

    title = models.CharField(_('title'), max_length=60, blank=True, null=True)
    body = models.TextField(_('body'))
    blog = models.ForeignKey(Blog, related_name="posts")
    user = models.ForeignKey(User)     
    comments = generic.GenericRelation(Comment)


class Comment(models.Model):

    content_type = models.ForeignKey(ContentType)
    object_id = models.PositiveIntegerField(_('object ID'))
    content_object = generic.GenericForeignKey()
    user = models.ForeignKey(User)  
    body = models.TextField(_('body'))

在视图中,我使用此结构检索所有帖子:

    posts = blog.posts.all()

所以我的问题是:

如何检索模板中所有帖子的所有评论?

我试过了,但没有显示评论:

{% for post in posts %}

  {{ post.title }} 
  {{ post.body }} 

      {% for comment in post.comments.all %}

         {{ comment.body }} 

      {% endfor %} 

{% endfor %}

2 个答案:

你错过了all

{% for comment in post.comments.all %}

答案 1 :(得分:1)

试试这个

{% for comment in post.comments_set.all %}
