我是django noob,我有一个django项目,模型设置如下:
class community(models.Model):
DIRECTION_CHOICES = (
(u'N', u'North'),
(u'S', u'South'),
(u'E', u'East'),
(u'W', u'West'),
(u'C', u'City'),
)
name = models.CharField(max_length=100)
direction = models.CharField(max_length = 1, choices=DIRECTION_CHOICES)
def __unicode__(self):
return self.name
class Meta:
verbose_name = "Community"
verbose_name_plural = "Communities"
我想添加一个模板页面,它只显示选项链接,如下钻取类型菜单:
***Communities***
* North
* South
* East
* West
* City
当您点击其中一个时,您会看到该区域中的社区列表。
我有办法吗
{% for area in choices %}
{{ area.name }}
{% endfor %}
...

如何将其添加到表单类并显示选项,如下所示: https://docs.djangoproject.com/en/dev/ref/forms/fields/#choicefield
或者,您可以在视图中返回选项,如下所示:
def main(request):
from app.models.community import DIRECTION_CHOICES
return render_to_response('my_template.html',
{'choices':DIRECTION_CHOICES},
context_instance=RequestContext(request))
并在您的模板中:
<select name="direction">
{% for k,v in choices %}
<option value="{{ k }}"/>{{ v }}
{% endfor %}
</select>
