问题描述
这是代码:
{% for o in page_obj.object_list %}
<tr style="color:#4A3C8C;background-color:{% cycle '#E7E7FF' '#F7F7F7' %};">
<td align="center"> {{o.terminal_id}}</td>
<td align="center"> {{o.time_stamp}}</td>
<td align="center" class="lat"> {{o.latitude|floatformat:"6"}}</td>
<td align="center" class="lng"> {{o.longitude|floatformat:"6"}}</td>
<td align="center"> {{o.speed}}</td>
<td align="center">
<script>
$("script").last().parent().parent()
</script>
</td>
<td align="center"> {{o.speed}}</td>
<td align="center"> {{o.adress_reality}}</td>
</tr>
{%endfor%}
我想在<$ c后得到下一个objcet $ c>'o'对象,
所以如何从'o'
object,
so how to get the next from the 'o'
object ,
或
如何获取python文件中的下一个对象,我可以在html中显示:
how to get the next object in the python file that i can show this in the html :
{{o.next_obj}}
{{ o.next_obj }}
谢谢
推荐答案
你尝试使用get_next_by_FOO吗?
did you try to use get_next_by_FOO ?https://docs.djangoproject.com/en/1.2/ref/models/instances/#django.db.models.Model.get_next_by_FOO
如果字段不是生成的,你可以添加到你的模型(天真):
If the field is not generated on the fly, you could add to your model (naively):
class MyObj(models.Model):
lat = ...
lon = ...
def get_next_by_id(self):
return self.objects.get(id=self.id+1)
并使用 {{o.get_next_by_id.lat}}
否则它对于,请参阅标签部分,但需要更多代码。
如果你给我一个更详细的例子,你可以尝试给你一个通用的模板,这可以在你的情况下工作。
Otherwise it is a good use for the templatetags, see the tag section but require more code.If you provide me a more detailed example of what you are doing i could try to give you a generic templatetag which might work in your case.
祝你好运。
