我一直在尝试显示与ManyToMany关系的模型的确切值,但我做不到,我所得到的全部就是接收QuerySet
<QuerySet [<Stack: PHP>, <Stack: js>]>
通过添加到模板标签
{{ brand.technologies.all }}
但是我想接收并显示2个字段,名称和图标。我已经尝试过像
这样的循环 {% for brand in brands %}
{% for technologies in brand.technologies.all %} {{ technologies.name }} {{ technologies.icon }} {% endfor %}
{% endfor %}
,但没有任何结果。语法没有问题,因为页面正在显示并且看起来像这样
models.py
STACK = (
('PHP', 'PHP'),
('js', 'JavaScript'),
...
)
STACK_ICONS = (
('/static/icons/stack/php.png', 'PHP'),
('/static/icons/stack/javascript.png', 'JavaScript'),
...
)

答案 0 :(得分:1)
我不明白您为什么突然通过brands
添加了一个外循环。您没有任何名为brands
的东西,并且已经通过brand
成功访问了所有其他数据。只需继续这样做,并删除外部循环即可。
<div class="technologies-wrapper">
{% for technologies in brand.technologies.all %} {{ technologies.name }} {% endfor %}
</div>
