Django:在模板中显示 ManyToManyField？

Question

我的 Django 项目中有这些模型:

class Area(models.Model):
    name = models.CharField(max_length=100, primary_key=True)
    def __unicode__(self):
        return self.name
class Place(models.Model):
    id = models.IntegerField(primary_key=True) 
    name = models.CharField(max_length=100, primary_key=True)
    area = models.ManyToManyField(Area,related_name='area')

如何在我的模板中显示地点的区域名称？目前我有:

{% for place in places %}
    Name: {{ place.name }}, Area: {{ place.area}}
{% endfor %}

给出:

Area: <django.db.models.fields.related.ManyRelatedManager object at 0x10435a3d0>

{{ place.area}} 只是空白。谁能帮忙？

在模板中使用place.area.all
http://docs.djangoproject.com/en/dev/topics/db/models/#extra-fields-on-many-to-many-relationships

{% for place in places %}
    Name: {{ place.name }}<br/>
    Area: <br/>{% for area in place.area.all %}{{ area }}<br/>{% endfor %}
{% endfor %}
