python - 遍历 django 模板中的 defaultdict(list) 结构

Question

我有一个像这样的结构my_dict:

defaultdict(<class 'list'>, {
   <MyClass: myobject1>: [<ThingClass: mything1>, <ThingClass: mything2>, ...],
   <MyClass: myobject2>: [<ThingClass: mything6>, <ThingClass: mything7>, ...], 
   <MyClass: myobject3>: [<ThingClass: mything45>, <ThingClass: mything46>, ...],
   ...
})

我想像这样遍历对象:

{% for object in my_dict %}
    {{object.somefield}}    
      {% for thing in object %}
          {{thing.somefield}}
      {% endfor %}
  {% endfor %}

如何循环遍历这个嵌套循环中的内容？ myobject1 不可迭代，那么如何获得可迭代对象？

Answer 1

您应该遍历字典的 .items() 以在每次迭代时同时获取对象和列表:

{% for obj, things in my_dict.items %}
    {{obj.somefield}}

    {% for thing in things %}
        {{thing.somefield}}
    {% endfor %}

{% endfor %}
