Comment other comments in Django

Question

I have a model for comments which uses GenericForeignKey and a model for posts.

class Comment(models.Model):
    content_type = models.ForeignKey(ContentType)
    object_id = models.PositiveIntegerField()
    content_object = generic.GenericForeignKey()
    text = models.TextField()
    comments = generic.GenericRelation('self')

class Post(models.Model):
    title = models.CharField(max_length=50)
    text = models.TextField()
    comments = generic.GenericRelation(Comment)

I can get all comments belonging to a post in templates with

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

but I need to comment other comments.

I can get 'next level' of comments with

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

    {% for sub_comment in comment.comments.all %}
        {{ sub_comment }}
    {% endfor %}
{% endfor %}

This way I can only get a specified number of levels.

How can I traverse all comments belonging to the post or belonging to other comments which are belonging to the post?

I smell Tree structure here.
For this in Django you can use: django-mptt

It adds several columns to your table and a lot usefull stuff to work with your model as a tree structure.

And it claims to be very efficient
