问题描述

我在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 = model.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Place的区域名称?目前我有:

  {%在地点%} 
名称:{{place.name}},区域:{{place.area}}
{%endfor%}

其中:

 区域:< django.db.models.fields.related.ManyRelatedManager对象在0x10435a3d0> 

{{place.area}} 只是空白任何人都可以帮忙?

解决方案

在模板中使用 place.area.all

  {%在地点%} 
名称:{{place.name}}< br />
区域:< br /> {%for places.area.all%} {{area}}< br /> {%endfor%}
{%endfor%}


I've got these models in my Django project:

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')

How can I show the Place's area name(s) in my template? Currently I have:

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

which gives:

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

And {{ place.area}} is just blank. Can anyone help?

解决方案

Use place.area.all in the template
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 places.area.all %}{{ area }}<br/>{% endfor %}
{% endfor %}
