模板循環，如果當前迭代是從以前的迭代

Question

我想有

{% for user_id, x, y in information %} 
    {% if it is the first time that user_id is different from the previous iteration %} 
     do something 
    {% elseif user_id is different from the user_id in the previous iteration %} 
     do something 
    {% endif %} 

誰能幫助不同。謝謝！！！

您正在尋找{% ifchanged %}。看看這裏：https://docs.djangoproject.com/en/dev/ref/templates/builtins/#ifchanged
