How do you limit list objects template side, rather than view side

One of the ways to limit objects is to add a limitation to a function like this

def ten_objects():
    obj = Model.objects.all()[0:10]  # limit to 10
    return {'objects': obj}

However how do you achieve this inside a template rather than inside a view?

I know you can filter through objects within a template and limit characters but how do you actually limit the amount of objects displayed in a loop. Via the template. for example the following code will loop through all objects....

    <ul>
     {% for new in news %}
      <li>
       <p>{{ news.title }}</p>
       <p>{{ news.body }}</p>
      </li>
     {% endfor %}
    </ul>

How do I break the loop, say after the firs 3 objects/items? And how do I do it inside the template?

There is a slice filter that you can use in templates. This works exactly the same as slicing within the view.

{% for new in news|slice:":10" %}

You want to use the slice template filter

Here's your example altered to use it:

<ul>
{% for new in news|slice:":3" %}
<li>
<p>{{ new.title }}</p>
<p>{{ new.body }}</p>
</li>
{% endfor %}
</ul>
