因此，我能夠弄清楚如何將字典鍵和值解包到 HTML 模板上，但是如果字典值是 QuerySet，我對如何解包感到有些困惑。例如，我將給定用戶的所有時間段傳遞到字典中。如何解包每個時間段的TimeSlot QuerySet的開始時間和結束時間等屬性？
這是我的 HTML 模板：
<table>
{% for key, value in user_info.items %}
{% for key2,value2 in value.items %}
<tr>
<td>{{key2}}</td>
<td>{{value2}}<td>
</tr>
{% endfor %}
<br>
{% endfor %}
</table>
我在 views.py 中的功能
def check_food_availibility(request):
food = FoodAvail.objects.all()
timeslots = TimeSlot.objects.all()
users_dict = {}
for i in range(len(user_info)):
user = {
"author": None,
"food_available": None,
"description": None,
"timeslot": None
}
user["author"] = user_info[i].author.username
user["food_available"] = user_info[i].food_available
user["description"] = user_info[i].description
if TimeSlot.objects.filter(time_slot_owner=user_info[i].author):
user["timeslot"] = TimeSlot.objects.filter(time_slot_owner=user_info[i].author)
users_dict[user_info[i].author.username] = user
return render(request, "food_avail/view_food_avail.html", {"user_info": users_dict})
這是它目前的顯示方式：
uj5u.com熱心網友回復：
嘗試這個
<table>
{% for key, value in user_info.items %}
{% for key2,value2 in value.items %}
<tr>
<td>{{key2}}</td>
{% if key2 == 'timeslot' %}
<td>
{% for i in value2 %}
i.start_time <-> i.end_time // just an example put your field here
{% endfor %}
</td>
{% else %}
<td>{{value2}}<td>
{% endif %}
</tr>
{% endfor %}
<br>
{% endfor %}
</table>
