我不知道是什么问题而且我已经被困在这里好几个小时了。可能有重复的问题,但没有一个可以让我脱离这个。
我在内部循环中使用if条件来检查inner的属性是否等于外部循环但是如果条件永远不为真,即使数据是相同的。
我已单独打印数据,这两个属性打印数据均值数据是否正确。但是,当我使用if条件时,它会转到其他地方
以下是我正在使用的数据:
activityy.activity_name = [Table Tennis,Swimming Pool, Football ]
slot.activity = [Table Tennis,Table Tennis,Table Tennis,Table Tennis,Swimming Pool, Football]
{% for activityy in all_activities%}
<div style="margin-left: 450px; padding: 15px; border-radius: 5px; background-color: #dfdfdf;height: 150px; width: 800px; margin-top: 20px; text-align: center">
{% for slot in all_slots %}
{% if slot.activity == activityy.activity_name %}
<div style="background-color: #3a589a; padding: 15px; width: 120px; height: 120px; float: left; border-radius: 5px;">
<span style="color: #f1f1f1; font-size: 20px;"> {{ activityy.activity_name}}</span><br>
</div>
{% else %}
<div style="background-color: #589a; padding: 15px; width: 120px; height: 120px; float: left; border-radius: 5px;">
<span style="color: #f1f1f1; font-size: 20px;"> {{ slot.activity}}</span><br>
</div>
{% endif %}
{% endfor %}
</div>
{% endfor %}
def activities(request):

template = loader.get_template('sklc/activities.html')

答案 0 :(得分:1)
我使用
解决了这个问题{% if slot.activity == activityy %}
Butt仍然不知道为什么它不能与 activityy.activity_name 一起使用,因为 activityy 和 activityy_activity_name 正在打印相同的东西。< / p>
