Question

What I already can do is this:

{% for _item in objects %}
    {{ _item.id }}
{% endfor %}

or this:

{% for i in 0..objects|length-1 %}
    {{ objects[i].id }}
{% endfor %}

To loop though the whole array.

What I want to do is:

• loop through a part of an array
• if the end of the array is reached: stop (instead of throwing an exception)

Kinda like this – depending on which is smaller (imagine there are only 5 items):

{% for i in 0.. (10 OR objects|length-1) %}
    {{ objects[i].id }}
{% endfor %}

What’s the easiest/shortest way of writing this?

EDIT

Of course, I could test it in my controller and than pass the result as a variable to the template, but isn’t there an easier way?

Answer 1

You’re looking for the slice filter.
