在Django模板中访问查询集对象 [英] Accessing query set object in django template

问题描述

我有两个模型，分别是 Human 和 Animal 。人的主键是动物模型中的外键。两者都有3列。人体模型具有c，e，r列。动物模型具有l，i，p列。我正在像这样的人类模型上运行一个Django查询。

I have two models, named as Human and Animal. The primary key of Human is foreign key in the Animal model. Both has 3 columns each. Human model has c, e, r columns. Animal model has l, i, p columns. I am running a django query on Human model, like this.

result = Human.objects.filter().order_by('r')

结果是一个查询集对象。该对象从我的视图文件发送到django模板页面。在模板页面内部，我遍历 result 并显示列值。

result is an queryset object. This object is sent from my view file to a django template page. Inside template page I am looping through result and displaying the column values.

现在我要做的是，我还想在同一django模板内的同一循环内获取 p 列（在Animal模型中存在）的值。

Now what i want to do is, I want to also fetch value of p column(which is present in the Animal model) inside the same loop, inside that django template. How can we do it in the django template page.

在python文件中，我可以这样做

In the python file I can do like this

for i in result:
    print i.animal_set.values()[0]['p']

但我想在模板页面中完成。

But I want to do it in the template page.

推荐答案

{% for record in result %}
    {{record.c}}, {{record.e}}, 
    {% for animal in record.animal_set|slice:":1" %}
        {{animal.p}}
    {% endfor %}
{% endfor %}
