django // отображаем данные с изменяемой переменной контекстного ключа

Question

Я пытаюсь отобразить rawqueryset данные в шаблоне. Однако эти rawqueryset столбцы не являются фиксированными, их можно изменить. Поскольку столбцы изменяются в диапазоне дат, опубликованных пользователем (запрос).

Например,

{% for foo in monthly_consult_by_dr %}
    <p>{{ foo.cnt_???? }}</p>
    <p>{{ foo.cnt_???? }}</p>
    <p>{{ foo.cnt_???? }}</p>
    <p>{{ foo.cnt_???? }}</p>
    <p>{{ foo.cnt_???? }}</p>
    <p>{{ foo.cnt_???? }}</p>
{% endfor %}

Но я могу выяснить, какой столбец включен в приведенный ниже код.

{% for key in monthly_consult_by_dr.colunms %}
    <p>{{ key }}</p>
{% endfor %}

## result
cnt_201812
cnt_201901
cnt_201902
cnt_201903
cnt_201904
cnt_201905
....

это мой views.py
