我有一个使用“列表”和“字典”组合创建的上下文。

数据结构如下所示。

{ 
   "Mike":[ 
      { 
         "month":"2020-02",
         "consult_counts_total":2,
         "consult_counts_total_uid":2
      },
      { 
         "month":"2020-01",
         "consult_counts_total":4,
         "consult_counts_total_uid":7
      },
      { 
         "month":"2019-12",
         "consult_counts_total":6,
         "consult_counts_total_uid":1
      }
   ],
   "Jaden":[ 
      { 
         "month":"2020-02",
         "consult_counts_total":8,
         "consult_counts_total_uid":12
      },
      { 
         "month":"2020-01",
         "consult_counts_total":23,
         "consult_counts_total_uid":11
      },
      { 
         "month":"2019-12",
         "consult_counts_total":2,
         "consult_counts_total_uid":19
      }
   ],
   "Sarah":[ 
      { 
         "month":"2020-02",
         "consult_counts_total":2,
         "consult_counts_total_uid":2
      },
      { 
         "month":"2020-01",
         "consult_counts_total":4,
         "consult_counts_total_uid":7
      },
      { 
         "month":"2019-12",
         "consult_counts_total":6,
         "consult_counts_total_uid":1
      }
   ],
   "John":[ 
      { 
         "month":"2020-02",
         "consult_counts_total":1,
         "consult_counts_total_uid":0
      },
      { 
         "month":"2020-01",
         "consult_counts_total":2,
         "consult_counts_total_uid":7
      },
      { 
         "month":"2019-12",
         "consult_counts_total":5,
         "consult_counts_total_uid":1
      }
   ]
}

我正在尝试通过模板中的循环显示此数据。

首先我尝试过。它显示了很好的结果。

{% for foo in context_data %}
    <p>{{ foo }}</p>
{% endfor %}


# result

Mike
Jaden
Sarah
John

但我无法获得更多深度数据。

例如，我想获取 Mike 的所有月份(2020-02、2020-01、2019-12)

第二次尝试..

{% for foo in context_data %}
    <p class="big">This is {{ foo }}'s months.</p>
    {% for foo2 in foo %}
        <p class="small">{{ foo2.months }}</p>
    {% endfor %}
{% endfor %}

# but it's showing nothing

第三次尝试..

{% for foo in context_data %}
    <p class="big">This is {{ foo }}'s months.</p>
    {% for foo2 in foo %}
        <p class="small">{{ foo2 }}</p>
    {% endfor %}
    <br>
{% endfor %}

# result
This is Mike's months.
M
i
k
e

第三个代码循环“Mike”字符串..不是 Mike 的数据。

我希望这样显示。

This is Mike's months.
2020-02
2020-01
2019-12

This is Jaden's months.
2020-02
2020-01
2019-12

This is Sarah's months.
2020-02
2020-01
2019-12

This is John's months.
2020-02
2020-01
2019-12

我该怎么办？

您仅迭代键，应该使用 items 到字典迭代值。

{% for key, values in context_data.items %}
    <p class="big">This is {{ key }}'s months.</p>
    {% for foo2 in values %}
        <p class="small">{{ foo2.month }}</p>
    {% endfor %}
    <br>
{% endfor %}
