循环在树枝上并在三次迭代后休息

Question

我有以下树枝代码:

{% for likeditem in user.getItemLikes() %}
    //iterate over each liked items here
{% endfor %}

但是我想只迭代前三项 user.getItemLikes()

我该怎么办？

Answer 1

看起来你可以使用切片过滤器来做你想做的事情:

{% for likeditem in user.getItemLikes()|slice(0,3) %}
    //iterate over each liked items here
{% endfor %}
