python - 字典中的类 - Django 模板

Question

可能是一个简单的问题，但我已经搜索了一段时间，但无法找到如何循环遍历字典中的所有项目并调用模板内的类项目的答案

我尝试过使用自定义模板标签，但语法似乎与我想要的不符。

这是我的代码:

data = [[OrderedDict([('token', 'XXXXXXXXXXXXXXX'), ('devices', [['Christmas Lights', 'XXXXXXXXXX'], ['Gold Beedrom Lamp', 'XXXXXXXX']])])], [[['5', 'off', 124], ['6', 'off', 124], ['7', 'off', 100], ['8', 'off', 124]]]]

#Dictionary and Class assignment

class LightStatus:
      def __init__(self,id):
          self.id = id
          self.state = None
          self.bri = None
      def add_data(self,id,state,bri):
          self.id = id
          self.state = state
          self.bri = bri

AllLights = dict()
for i in data[1]:
    for light in i:
        id = light[0]
        state = light[1]
        bri = light[2]
        AllLights[id] = LightStatus(id)
        AllLights[id].add_data(id,state,bri)

我想在模板中包含什么:

#What I want to do in the template      
for i in AllLights:
    print(AllLights[i].id)
    print(AllLights[i].state)
    print(AllLights[i].bri)
return render(request, 'file.html', 'lights': AllLights)

#What I've tried
{% for light in lights %}
    {% for i in light %}
       {{lights.light.id}} #light being the variable from above.                
    {% endfor %}
{% endfor %}

我还尝试过使用自定义模板标签:

from django import template
register = template.Library()

@register.filter
def lights(LightDict, i):
    return LightDict[int(i)]
#template 
{{ AllLights|lights.forloop.counter0 }} 

总结一下我想做的事情。我想将 AllLights 字典传递到我的模板，然后循环遍历所有键并调用 id、state 和 bri 每个键。

更新:

有人问我在渲染之前打印(AllLights)时会发生什么:

{'5': <dashboard.views.LightStatus object at 0x106f016a0>, '6': <dashboard.views.LightStatus object at 0x106f01320>, '7': <dashboard.views.LightStatus object at 0x106f01ac8>, '8': <dashboard.views.LightStatus object at 0x106f014e0>}

您(正确地)使用有序字典来维持顺序，因此假设该字典中的顺序是所需的顺序，您应该能够在模板中迭代有序字典的值 :

{% for light in all_lights.values %}
  {{ light.id }}
  {{ light.state }}
  {{ light.bri }}
{% endfor %}
