Django, How to filter context output from HTML template?-CodePudding

I have a ListView that sends context as news in the HTML template.

The below code is supposed to slice the context array from the 4th element to until its end

{% for post in news[4:0] %}
............
{% endfor %}

But following error occurs

Could not parse the remainder: '[4:]' from 'news[4:]'

CodePudding user response：

You can use the slice template tag:

{% for post in news|slice:"4:" %}
............
{% endfor %}

You can do this inside your ListView by overriding the context data like this:

def get_context_data(self, **kwargs):
    context = super().get_context_data(**kwargs)
    context['last_4_news_items'] = News.objects.all().order_by('-date')[:4]
    return context

template:

{% for news in last_4_news_items %}
    {{ news }}
{% endfor %}
